The cable network in the outdoor environment is subject to a variety of environmental challenges, including extreme weather, vehicle damage, and more. Similarly, accidentally touching a fiber end-face and dirty environments are well-known causes of contamination.

Regular fiber cleaning, inspection, and maintenance will help to eliminate these issues and prevent any disruption to the service. Fiber maintenance and cleaning are not just important; it is critical to the long-term reliability of any network. In fact, it sits at the heart of successful fiber deployment.

The Internet is crucial for us to weather unexpected events. We need it for communication, news, provisioning, entertainment, work, health, education, and other activities. A recent study from the Fiber Broadband Association shows dramatic shifts in the use of advanced applications that require both strong upload and download capacity.

For instance, there is a significant rise in the use of video conferencing, online gaming, and video streaming — all of which require high levels of reliable bandwidth. This is where fiber maintenance comes into play. In order to continuously provide reliable service, network operators must actively monitor the integrity of the optical fiber infrastructure.

Increasingly, fiber has become the go-to option for data center architecture due to its numerous benefits, including greater bandwidth, smaller size and weight, and error-free transmission over longer distances. As more data center fiber is deployed to meet demands, effective fiber maintenance and management become vital to ensure data center uptime and efficient operations.

A routine fiber inspection and maintenance will protect the cables from external interference — such as bent or crushed cables, thus preventing any performance issues during day-to-day operations. High-density solutions that can provide scalability i.

the ability to support more fiber connections in the future are also critical to maintaining data center reliability and operations. Learn more about fiber inspection and fiber testing on our website.

Fiber Optics and a Preventative Maintenance Schedule - Ring and Ping First, determine that the communications equipment on both ends of the link work properly. Avoid getting them damaged by handling them with extreme care. Those can be expensive mistakes! Of course not. So what periodic maintenance should be done on fiber optic networks? 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. Key Takeaway: Establish comprehensive documentation, including cable records, test results, and maintenance logs, and regularly update them.

Safety can also be an issue. Links operating at gigabit and higher speeds generally use nm VCSELs, which are relatively high power lasers at a wavelength near the high end of human eye sensitivity, still visible to some people.

Using a high power microscope, like a X, concentrates the light into the eye, increasing the risk of eye damage, especially if you are not able to see this wavelength.

The fiber link loss may be different when a link is reassembled after inspection, especially with connectors that have spring loaded ferrules like STs.

Inspecting a connection could lead to higher loss than initially measured and potentially affecting data transfer on systems like Gigabit Ethernet and 10G Ethernet where loss margins are very low.

As for testing with an OTDR for maintenance inspection, some telcos do that automatically on spare fibers in outside plant cables that run tens or hundreds of kilometers through desolate regions. An OTDR, unless it is very high resolution, is inappropriate for most premises systems under any circumstances and often causes more problems that it solves.

Finally, if you have a problem with dust in a telecom closet, room or data center, you have a poorly designed facility that should be fixed with proper sealing, filtration and air conditioning.

You should not try to fix it with a feather duster. So what periodic maintenance should be done on fiber optic networks?

Let's take a different viewpoint - how do you design a system that is going to be reliable and not need maintenance or repair?

That makes a lot more sense. Let's look at some things you can do to ensure reliability. Design the cable plant to be protected.

Bury it deep enough to prevent most dig-ups 1. Put it in conduit or innerduct where it is exposed. Use racks and patch panels with locking doors. Ensure the cable was installed properly and is stress-free. Follow guides for pulling tension and bend radius. Do not let long cables hang on connectors causing stress on the connector.

Do not bundle patchcords tightly enough to cause stress. Check fibers in splice closures to ensure they are stress free. In addition, the IEC has created a set of standards called the Basic Test and Measurement Procedures Standard for Fiber Optic Interconnecting Devices and Passive Components.

It is extremely important that during the maintenance every end-face be cleaned, not only the ones that are easy to access. Contaminants can easily migrate from one port to another. In a systematic process, each end face should be inspected, if it fails the inspection under the microscope, it should then be cleaned and inspected again.

If after cleaning it still does not meet the necessary standards, it should be replaced. While this may seem costly, it is much less expensive to maintain than have your entire network fail due to neglect.

Only two cleaning tools are necessary, wipes and solvent. FTTB Environmental Maintenance Preventative Maintenance. Maintenance Break-fix Maintenance Reactive Maintenance Fault Investigation.

Community Impact. Preventative Maintenance. We stay on top of the Network. As part of our maintenance recommendations we suggest having a full-time team in the area assessing and working on the following to prevent any major network issues: Regular quality audits, checking that all slack is managed on cables, all dome joints are up and all slack boxes are closed.

Updating as-built as needed. Attending to issues before they are logged. Recording network health every time the team can. Sending monthly reports on the status of the network. Reactive Service. Environmental Maintenance.

All about the environment.

Fiber Optic Network Install

Fiber optic network maintenance -

Cables holding tens, hundreds or even thousands of fibers 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 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. Just one tiny spec of dust can wreck havoc on your network and cause you costly downtime. Many people install their fiber optic cabling with the recommended dust covers and caps, thinking it means no cleaning or maintenance will be required but that is absolutely incorrect.

Even with preventative dust covers, it is still possible for contamination to occur. In fact, the plastic in the dust caps tend to deteriorate over time and ends up leaving a residue on the end-faces they cover.

Any time an end-face is exposed to the environment, it is subject to contamination, especially in the presence of static electricity. There is a three-step process for cleaning fiber: inspect, clean, and inspect again. Inspection should be done not only visually, but also with a video microscope specifically designed to inspect fiber.

In the early days of fiber optics, some network owners tried building automatic monitoring systems to keep tabs on the loss of the cable plant. That idea faded when fiber proved to be much more reliable than copper cabling and the network communications manufacturers built monitors for data transmission into their equipment, a more reliable indicator of problems.

Let me give you some reasons why you do not want to try to do maintenance on any fiber optic network: Most inspection procedures require bringing the network down, unacceptable in almost every instance.

Telcos have backup links running alongside operational links and the equipment will switch over to the backup if it senses high errors on the main link. Do you know any premises networks set up like that? Want to bring down an OC telco link or gigabit LAN backbone fast?

Unplug a fiber optic connector to inspect it with a microscope. See how long it takes the network manager to find you.

Most harm to installed fiber optic systems and copper also is done during handling by unskilled or clumsy personnel. We heard of one network that crashed when a executive of a company disconnected a fiber connector to show it to a visitor they were escorting around the facility. We know of workers accidentally backing into patch panels and breaking cables at the junction to the connector.

It's easy to get dirt into mating adapters or on connectors whenever they are exposed to the air. Fiber technicians are taught to keep connections clean after termination, cover connector ferrules and mating adapters with dust caps and clean the ferrule end whenever it is opened to the air.

If dirt is such a big problem and airborne dirt is the size of the core of singlemode fiber , why risk contaminating operating connectors by exposing them to the air to see if they are dirty? Systems should be designed to protect components from dust in the environment - that's what cable plant hardware is for.

Mating and unmating may wear the connector interfaces, affecting optical performance. Ferrule endfaces rubbing against the mating connector and the outside of the ferrule scraping materials off the alignment sleeve in the mating adapter, especially with adapters using cheap plastic alignment bushings which are good for only a few mating cycles, can cause higher loss.

Safety can also be an issue. Links operating at gigabit and higher speeds generally use nm VCSELs, which are relatively high power lasers at a wavelength near the high end of human eye sensitivity, still visible to some people.

Using a high power microscope, like a X, concentrates the light into the eye, increasing the risk of eye damage, especially if you are not able to see this wavelength. The fiber link loss may be different when a link is reassembled after inspection, especially with connectors that have spring loaded ferrules like STs.

Inspecting a connection could lead to higher loss than initially measured and potentially affecting data transfer on systems like Gigabit Ethernet and 10G Ethernet where loss margins are very low.

However, many things could potentially slow down the transmission of data, such as contaminated connectors and congested networks.
