Fiber optic network maintenance -

Nothing can be more frustrating than having to wait for components necessary for repairs. When building a network, order extra cables and hardware for installation as insurance.

Leftover components should be stored in a box along with a restoration plan that includes documentation such as cable route diagrams, test results — especially OTDR traces — and any other information that could help locate and fix a problem in the cable plant.

The design should also include burying marker tape that can be found with cable-location equipment about a foot underground above the cable. That provides two layers of protection. Restoration planning should be part of the design. If it was not done originally, now is the time to do it before something happens.

Quickly find the problem and mobilize the personnel to fix it. Start with some quick checks. Do not jump to the conclusion that the problem is the cable plant.

First, determine that the communications equipment on both ends of the link work properly. Start with a simple check of system power.

If multiple links operate over the same cable plant, diagnosis is easier. A cleaning kit will quickly remove dirt and contamination, and a video microscope can inspect connectors for dirt or damage.

If the electronics are the problem or are suspected, swap modules for spares. If that solves the problem, make sure to send that bad module out for repair ASAP.

They can be tested with an inexpensive visual fault locator VFL to confirm they have not been broken or connected wrong. A connector inspection microscope and cleaning kit are a good investment too, since the majority of fiber optic problems are due to dirty connectors.

Diagnosing cable problems is a matter of shooting several spare fibers in the cable with an optical time-domain reflectometer OTDR and analyzing the traces. Is the cable the expected length?

Test a few and see what they all look like. If they are all the same, you may have a cable break. If only some fibers show the problem, you may have cable damage in only a few fibers, indicating a problem with a kinked but not totally broken cable or problems at a splice point. An OTDR with long launch and receive cables will help diagnose problems in the cable plant.

Compare the length on the OTDR with data from installation testing and correlate with splice points to reduce location uncertainty. Alternatively, shoot from both ends to locate a break and average distances.

Make certain you are testing the correct cable. Using OTDR testing, one crew thought they had a break in a 6 km underground cable at 4 km. But physical inspection, including digging at the location indicated by the OTDR, showed no problem. In fact, they were testing the wrong cable.

They were testing a cable 4km long running in the opposite direction from the patch panel, not the cable they thought they were testing. This is where documentation helps. Having information on the length of the cable and the location of splice points — especially geographic information system GIS data — makes pinpointing problems easier.

Comparing traces of problem fibers allows correlation of the problem location to the location of a splice closure or a service loop in a vault. Splice closures can be the problem. Fibers can get cracked or broken in splice trays, yet not fail for a long time, perhaps after seasons of temperature changes.

Splice closures can be improperly sealed, and moisture — or ice in winter — will cause damage. There are even tales of animals such as squirrels or woodpeckers attacking splice closures or cables and causing damage.

Finding a fiber break in a splice tray can be difficult. If you are close enough to use a visual fault locator VFL , it will pinpoint the break.

If the distance to the nearest fiber end is more than km, a gadget called a fiber identifier may be used. A visual fault locator VLF is extremely useful at finding breaks in splice trays, couplers, etc. Sometimes a visual inspection of a cable route will find the cause of the break faster than testing fibers.

One tech remembers that a construction team was installing road signs nearby when their network went down, so he hopped in his truck and drove to the job site. There he found the construction crew stuffing the broken fiber optic cable back into the hole they had dug with an auger.

Another network went down when a helicopter flew into an optical power ground wire OPGW on a tower. That one was easy to find, but hard to fix, but one of our FOA instructors spliced it from a precarious perch in a bucket truck.

And always remember to ask around the offices to see if someone has been working on the network. Restoration can be in a muddy field along a rural road or in the middle of a busy street in downtown Los Angeles.

Okay, there is a break. How do you fix it? You should have a restoration plan and a restoration kit complete with up-to-date documentation, a list of test and repair equipment — including where to find them — and components set aside for repair. A contact list of knowledgeable people on staff or a contractor on call is also necessary.

Many companies use contractors to install fiber optic cabling because they do not have qualified employees to do the work, or at least not enough with the experience and equipment to do the job.

Attending to issues before they become issues like fibre that has lost its tension over time can be attended to before it is reported.

Reactive maintenance could be any issue the team would need to respond to. This could be a call for a huge break and would need a team to rectify. MTD has an in-house civil team equipped to rectify an aerial network issue including planting poles, stringing fibre, trenching and reinstating any surface including tar.

Reactive maintenance requires the reaction team to be ready for any situation this includes holding the material required to rectify the issue. MTD will have every core fibre, every size dome joint, dead-end hooks and poles in stock at all times.

We aim to ensure that the environment is not damaged nor does the network get damaged by the environment. Environmental maintenance is very important to ensure that the network and the environmental impact is managed on a regular basis.

Regular environmental maintenance means overgrown trees surrounding cables are trimmed back, and slack bins are checked as birds commonly try nesting here. We aim to have the nest relocated before it is completed.

Beehives have to be spotted and removed before they are formed, if not professionals need to be called in to relocate the bees. By having a permanent team on-site monitoring our networks the best maintenance service possible can be offered to our clients. Skip to content. Fibre Network Maintenance.

The Basics - What Does A Manager Need To Know? Fiber optic communications is quite simple. Instead of sending signals as pulses of electricity maintenabce radio waves, maintenancw optics uses pulses of light transmitted down a hair-thin ultra-pure strand of glass.

Cables holding tens, hundreds or even thousands of Fiiber can be run underground, aerially on poles or even under water. Construction of a fiber optic cable plant is similar to that of any other cable and there are thousands of trained and FOA-certified techs available to build fiber optic networks.

Managers need to know the basics, the jargon, and how to communicate with suppliers, contractors and installers. Forget the physics and optics - not even installers need to know the technology that makes fiber optic communications possible. Managers do need to learn about fiber optic components like the types of fibers singlemode or multimode used in various networks to ensure the proper ones have been chosen for the installation.

We prevented a manager recently from ordering tens of miles of outside plant cable with the wrong fiber - multimode not singlemode. Hopefully a sales person, distributor or manufacturer would have questioned his choice but if not, he would be stuck with a large amount of virtually worthless cable.

They should also learn about cables and their applications. We've seen specs for direct burial armored cables that were to be pulled through conduit and non-armored cable designed into a project for direct burial. We've seen indoor cable specified for outdoor installation and outdoor cable specified for premises installation.

You must know what is the proper cable choice for the installation. Fiber optic connector compatibility is another important issue.

Twice recently I have been asked by managers about the difference between PC physical contact and APC angled physical contact connectors and whether they are compatible. They certainly are not and may be damaged by mating to the wrong type. But try to find that advice on a manufacturer's or distributor's website - they expect everyone to know that already.

Those can be expensive mistakes! A few minutes learning the basics from books or online at Fiber U or the FOA website can answer those questions and prevent some big problems. Or just call us at the FOA – that's what many people do.

Don't believe the classic "myths of fiber optics. The pure glass in optical fiber is many times stronger than steel and fiber optic cable is much more flexible than coax or twisted pair copper cable.

Even 30 years ago, fiber had the bandwidth and distance advantages that made communications over fiber optics cost only s few percent as much as over copper or microwave radio.

Today we can put almost one million times more communications over fiber than back then. And finally, there are more thanskilled installers who have installed millions of miles of fiber and will attest to the fact that it's just another skill to learn.

To learn about the basics of fiber optics, start with Fiber Optic Jargon-Illustrated - learn to speak the language of fiber optics.

Consider getting a copy of our basic fiber optics or outside plant fiber optics textbooks as a reference for your bookshelf. The Design It is at the design stage that the manager has the most important role in the success of a fiber optic project. This is not a time to delegate without oversight.

The manager must be able to evaluate options presented and make decisions based on the input of many others. If someone who works for you is designing a fiber optic network, they need to know whether it provides the communications capacity you need for today and over its projected lifetime.

Are there enough fibers for spares and future expansion? Can the network support drops to new user locations? Has the network been designed optimally for both performance and cost? Are all the components chosen appropriate for the network. Is the network secure and are you prepared to restore outages?

One good test is to create a scope of work SOW and send out a request for proposal RFP to some experienced contractors for comments. FOA has a complete textbook on fiber optic network design but the basics are summarized on this page in our FOA Guide online.

Construction And Installation Fiber optic cable plants can be installed outside called "OSP" for outside plant or indoors called "premises". The OSP cable plant can be installed underground, aerial or under water.

All have various techniques that can be chosen depending on the geography of the route or local requirements, for instance that all cables must be placed underground. Premises cabling is often a mix of fiber optics and copper cabling.

It will be covered by codes like the NEC to ensure safety for those inside the building. The FOA Guide has a section on Construction and another on Installation.

The Contractor How do you evaluate contractors? The top of the list of requirements is experience in similar jobs backed by great references. Are their designers, managers and installers properly trained and certified? How much personnel turnover do they have?

What's their plan for on-the-job training OJT for new recruits? Are they fully equipped for the job? What other jobs are they qualified for? Electrical construction and fiber optics are often done by the same contractor - although by different divisions of the same company - and may yield more efficient construction when electrical services are required in communications facilities.

If the contractor is chosen in a bid process, don't blindly choose the lowest bidder. Include in the RFQ request for quotation requirements for the bidders to include lots of information about the company that will allow evaluation of their ability to complete the job properly, including company history, personnel, structur e, financial historyworker credentials, experience and of course references.

We've seen jobs go to the lowest bidder where the contractor installed thousands of splices and connectors improperly, submitted erroneous test data, got paid and disappeared, leaving the network owner holding the bag. In another case of improper installation, the contractor went bankrupt when forced to redo the job correctly.

Choosing a fiber optic contractor. Evaluating The Quality Of An Installation If the contract covers both electronic equipment and fiber optic cable plant, the number one concern is if the communications system works as planned.

Under any circumstances, the quality of the fiber optic cable plant needs to be evaluated independently. Every step of the way should be documented and inspected to ensure that the network was installed in a "neat and workmanlike manner.

Fiber optic testing is a complex process that requires a trained and experienced tech to perform properly. Here is a summary of fiber optic testing procedures from the FOA Guide. Documentation Too many networks have inadequate documentation, insufficient to evaluate the installation, allow moves, adds and changes MACs or restoration in an emergency.

Many managers and installers think the documentation is created after the network is built, but that's completely wrong. Network documentation starts when the idea of the network is conceived, evolves through the design, creation of the scope of work SOWRFP and RFQ request for quoteinstallation and testing.

Documentation should be one of the legal requirements of the contract for network installation. The installer should get the final payment only after they submit all the documentation required, not before. Documentation must include the route of the cable plant and the type of installation aerial, underground, etc.

The documentation must include the path of every cable, every fiber in the cable with color codes and the test results from testing each fiber. If that sounds like a lot of work and a lot of data, it is, but that's what's necessary to determine what has been installed and if it was installed according to the plans.

In conclusion, maintaining fiber optic cables involves addressing common issues such as cable damage, connector contamination, cable tension, environmental factors, and the lack of documentation and testing.

By proactively addressing these challenges and following industry best practices, network administrators can ensure optimal performance, reliability, and longevity of their fiber optic cable infrastructure.

How to Identify and Resolve Fiber Optic Cable Problems However, like any other technology, fiber optic cables are not immune to problems.

In this article, we will explore how to identify and resolve common fiber optic cable issues, ensuring optimal performance and reliability for your network.

Signal Loss One of the most common problems associated with fiber optic cables is signal loss. Signal loss occurs when the strength of the transmitted data diminishes as it travels through the fiber. Various factors can contribute to signal loss: Macro bends: Excessive bending of fiber optic cables can cause signal loss.

Avoid sharp bends and kinks during installation. Dirty connectors: Dust, dirt, or contaminants on the connectors can obstruct the transmission of light, resulting in signal loss.

Regularly clean and inspect connectors. Fiber splicing issues: Improper splicing techniques can introduce losses. Ensure that splices are done correctly and efficiently. To resolve signal loss issues: Inspect and clean connectors regularly to remove any contaminants.

Ensure proper cable management to avoid excessive bending or stressing of the fibers. In case of severe signal loss, consider optical amplification techniques like erbium-doped fiber amplifiers EDFAs to boost the signal.

Fiber Breaks Fiber breaks refer to complete fractures in the fiber optic cable, resulting in a complete loss of signal transmission. Fiber breaks can occur due to: Physical damage: Accidental bending, crushing, or cutting of cables can lead to fiber breaks.

Avoid excessive force or pressure on the cables. Environmental factors: Harsh environmental conditions like temperature fluctuations, moisture, or rodents can damage fiber optic cables.

Properly protect and route cables to prevent exposure. To identify and resolve fiber breaks: Perform regular visual inspections of the cables to identify any visible signs of damage or breaks. Use an optical time-domain reflectometer OTDR to locate the exact position of the break in the cable.

Replace the damaged section of the cable or consider splicing the fibers back together for a temporary fix. Attenuation Attenuation is the gradual decrease in signal strength over the length of the fiber optic cable. Excessive attenuation can result in data errors and reduced performance.

Factors contributing to attenuation include: Fiber type: Different types of fiber optic cables have varying attenuation characteristics. Choose the appropriate fiber type for your specific application.

Distance: The longer the transmission distance, the higher the attenuation. Use appropriate amplification techniques for long-haul transmissions.

To mitigate attenuation: Choose fiber optic cables with lower attenuation values for long-distance applications. Consider using dispersion compensating modules to decrease dispersion-related attenuation.

Optimize the overall design and configuration of the network to minimize signal loss. Key Takeaways Regularly inspect and clean connectors to prevent signal loss caused by contaminants.

Avoid excessive bending or stressing of fiber optic cables to minimize signal loss. Properly protect cables from physical damage and harsh environmental conditions. Managers do need to learn about fiber optic components like the types of fibers singlemode or multimode used in various networks to ensure the proper ones have been chosen for the installation.

We prevented a manager recently from ordering tens of miles of outside plant cable with the wrong fiber - multimode not singlemode. Hopefully a sales person, distributor or manufacturer would have questioned his choice but if not, he would be stuck with a large amount of virtually worthless cable.

They should also learn about cables and their applications. We've seen specs for direct burial armored cables that were to be pulled through conduit and non-armored cable designed into a project for direct burial.

We've seen indoor cable specified for outdoor installation and outdoor cable specified for premises installation. You must know what is the proper cable choice for the installation.

Fiber optic connector compatibility is another important issue. Twice recently I have been asked by managers about the difference between PC physical contact and APC angled physical contact connectors and whether they are compatible.

They certainly are not and may be damaged by mating to the wrong type. But try to find that advice on a manufacturer's or distributor's website - they expect everyone to know that already.

Those can be expensive mistakes! A few minutes learning the basics from books or online at Fiber U or the FOA website can answer those questions and prevent some big problems.

Or just call us at the FOA – that's what many people do. Don't believe the classic "myths of fiber optics.

The pure glass in optical fiber is many times stronger than steel and fiber optic cable is much more flexible than coax or twisted pair copper cable. Even 30 years ago, fiber had the bandwidth and distance advantages that made communications over fiber optics cost only s few percent as much as over copper or microwave radio.

Today we can put almost one million times more communications over fiber than back then. And finally, there are more than , skilled installers who have installed millions of miles of fiber and will attest to the fact that it's just another skill to learn.

To learn about the basics of fiber optics, start with Fiber Optic Jargon-Illustrated - learn to speak the language of fiber optics. Consider getting a copy of our basic fiber optics or outside plant fiber optics textbooks as a reference for your bookshelf.

The Design It is at the design stage that the manager has the most important role in the success of a fiber optic project. This is not a time to delegate without oversight. The manager must be able to evaluate options presented and make decisions based on the input of many others.

If someone who works for you is designing a fiber optic network, they need to know whether it provides the communications capacity you need for today and over its projected lifetime.

Are there enough fibers for spares and future expansion? Can the network support drops to new user locations? Has the network been designed optimally for both performance and cost? Are all the components chosen appropriate for the network.

Is the network secure and are you prepared to restore outages? One good test is to create a scope of work SOW and send out a request for proposal RFP to some experienced contractors for comments.

FOA has a complete textbook on fiber optic network design but the basics are summarized on this page in our FOA Guide online. Construction And Installation Fiber optic cable plants can be installed outside called "OSP" for outside plant or indoors called "premises".

The OSP cable plant can be installed underground, aerial or under water. All have various techniques that can be chosen depending on the geography of the route or local requirements, for instance that all cables must be placed underground.

Premises cabling is often a mix of fiber optics and copper cabling. It will be covered by codes like the NEC to ensure safety for those inside the building. The FOA Guide has a section on Construction and another on Installation. The Contractor How do you evaluate contractors?

The top of the list of requirements is experience in similar jobs backed by great references. Are their designers, managers and installers properly trained and certified? How much personnel turnover do they have? What's their plan for on-the-job training OJT for new recruits? Are they fully equipped for the job?

What other jobs are they qualified for? Electrical construction and fiber optics are often done by the same contractor - although by different divisions of the same company - and may yield more efficient construction when electrical services are required in communications facilities.

If the contractor is chosen in a bid process, don't blindly choose the lowest bidder. Include in the RFQ request for quotation requirements for the bidders to include lots of information about the company that will allow evaluation of their ability to complete the job properly, including company history, personnel, structur e, financial history , worker credentials, experience and of course references.

We've seen jobs go to the lowest bidder where the contractor installed thousands of splices and connectors improperly, submitted erroneous test data, got paid and disappeared, leaving the network owner holding the bag.

In another case of improper installation, the contractor went bankrupt when forced to redo the job correctly. Choosing a fiber optic contractor.

Evaluating The Quality Of An Installation If the contract covers both electronic equipment and fiber optic cable plant, the number one concern is if the communications system works as planned.

Under any circumstances, the quality of the fiber optic cable plant needs to be evaluated independently. Every step of the way should be documented and inspected to ensure that the network was installed in a "neat and workmanlike manner.

Fiber optic testing is a complex process that requires a trained and experienced tech to perform properly. Here is a summary of fiber optic testing procedures from the FOA Guide. Documentation Too many networks have inadequate documentation, insufficient to evaluate the installation, allow moves, adds and changes MACs or restoration in an emergency.

Many managers and installers think the documentation is created after the network is built, but that's completely wrong. Network documentation starts when the idea of the network is conceived, evolves through the design, creation of the scope of work SOW , RFP and RFQ request for quote , installation and testing.

Documentation should be one of the legal requirements of the contract for network installation. The installer should get the final payment only after they submit all the documentation required, not before.
