FOSCO Connect (Fiber Optics For Sale Co. - fiberoptics4sale.com) was founded in by fiber-optic networking expert Colin Yao. Since then, the company has grown to be one of the nation's largest stocking distributors of fiber-optic datacom and telecom networking products, with multi-million dollar annual sales.

On its website, FOSCO Connect recently published its informative 101 Guidelines for Fiber Optic Cable Installation. The technical article's top guidelines for fiber-optic cabling cabling installation are shared below with the company's permisson.
Per experts at FOSCO Connect, the top 10 guidelines for fiber-optic cabling installation are as follows:
3. Never exceed the cable bend radius. Fiber is stronger than steel when you pull it straight, but it breaks easily when bent too tightly. This will harm the fibers, maybe immediately, maybe not for a few years - but you will harm them and the cable must then be removed and thrown away.
4. Always roll the cable off the spool instead of spinning it off the spool end. This will put a twist in the cable for every turn on the spool! Never twist the fiber cable. Putting a twist in the cable can stress the fibers too.
5. Make sure your fiber cable is long enough for the run. Fiber splicing make things complicated and expensive. And it needs special protection. Try to make it in one pull.
6. Indoor cables can be installed directly, but you might consider putting them inside innerduct. Innerduct provides a good way to identify fiber optic cable and protect it from damage, generally a result of someone cutting it by mistake! You can get the innerduct with pulling tape already installed.
7. Plan the Installation. Create a detailed, written plan of installation. You can eliminate 95% of the problems installers can encounter by simply creating this plan. The plan should include equipment and supplies, fiber cable specification, location of equipment, testing requirements, data forms for testing, personnel experience level and assignment, installation methods, identification of potential problem areas, safety issues, etc.
8. Pull, do not push cables. Pushing can result in violation of the bend radius.
9. Monitor the supply reel. Monitoring the supply reel during installation is necessary to prevent violation of minimum bend radius.
10. Communicate along the path of installation. When installing long runs, communicate and monitor along the path of the installation. Fiber cables can and do jump from unmonitored pulleys. The minimum crew should have one person monitoring the pulling equipment, one monitoring the supply reel, and one coordinating all involved in the installation.

1. Entrance Facilities (EF). Telecom facilities entering a building or residence from the outside -- from a local service carrier or private network -- pass through an opening in the exterior wall via a conduit. This cabling enters a room where other devices are deployed, including network connection points, patch panels, equipment racks, hardware connectors, power supplies and protection devices for grounding, shielding and lightning protection.
2. Equipment Room (ER). The area where entrance cabling connects to the internal building wiring infrastructure is the equipment room. It houses patch panels that provide connections for backbone cabling, horizontal cabling and intermediate cabling. As this room may also house network switches, PBXs, servers and other devices, it should be environmentally controlled to ensure that temperature and relative humidity levels are maintained according to equipment vendor specifications.
3. Backbone Cabling. Also called riser cabling -- as it typically is installed in vertical channels, or risers, that connect to each floor -- backbone cabling links EF, telecommunications and other ERs, and carrier spaces. Two subsystems have been defined for backbone cabling:
The cable types used in backbone cabling include the following:
Note: Entrance cables are usually determined by the carrier and are not the user's responsibility.
4. Telecommunications Room (TR) and Telecommunications Enclosure (TE). This environmentally controlled area can be a dedicated room (TE) or part of another larger room (TR), such as a general utility room. Hardware in these spaces terminate horizontal and backbone cables. It's also where local cables, called jumpers or patch cords, are used on patch panels to cross-connect different cables. ICs or MCs may be installed here as well to provide additional connection resources.
5. Horizontal Cabling (Cabling Subsystem 1). Getting telecom resources to users at their work areas or other rooms on a floor is the job of horizontal cabling. A typical cable run goes from the user's device to the nearest TR on the same floor. The maximum allowed cable length between the TR and user device is 295 feet, regardless of cable type.
Horizontal cabling includes the cable, connectors, patch panels, jumpers and patch cords in the TR/TE. They may also include multiuser telecommunications outlet assemblies and consolidation points to connect multiple devices or cables in a single connector.
The cable types used in horizontal cabling include the following:
6. Work Area (WA). The area from a connector, or jack, in a wall outlet to a user device using a cable is considered the WA. It's the final destination of a structured cable system.
Structured cabling has greatly simplified the process of installing voice and data communications equipment. Its continued use means new equipment, such as IoT systems, will be easily supported.
