The FOA Reference For Fiber Optics - Outside Plant Fiber Optics. The purpose of this website is to provide a reference guide to those involved with outside plant fiber optic networks, either in design, installation, use, maintenance or troubleshooting, or those teaching the personnel who will work with it. Outside Plant Fiber Optic Cables. HCA's outside plant (OSP) fiber optic cables are designed to withstand the installation and stresses inherent in cables exposed to the external environment. Tough polyethylene jackets with carbon black protect the fibers from the harsh sun and water conditions. In telecommunication, the term outside plant has the following meanings: In civilian Outside plant cabling, whether copper or fiber, is generally installed as aerial They can be used to house and protect copper, coaxial, and optical fiber  ‎Context · ‎Protecting equipment in · ‎Handholes and other · ‎Corrosion resistance.

Many courses are criticized because they are too specific or prejudiced to one application, technology or manufacturer.

We will explore the spectrum with you and tell you where to go to find out more. This program has been developed as a cooperative effort of many volunteers from the FOA.


If you have comments or suggestions on how to improve it, please contact us at info foa. This Fiber U self-study program will divide the basics of fiber outside plant fiber optics into a number of smaller topics.

With the companion printed books, we address the needs for those who prefer printed books or who must have them to meet academic requirements. Hopefully the drawings are available as CAD files so you outside plant fiber optics have a copy to do the network cabling design in your computer, which makes tweaking and documenting the design so much easier.

If the building is still in the design stage, you may have the opportunity to provide inputs on the needs of the cable plant. Ideally, that means you can influence the location of equipment rooms, routing of cable trays and conduits, availability of adequate conditioned power and separate data grounds, sufficient air-conditioning and other needs of the network.

Outside plant OSP cabling installations have enormous variety depending on the route the cable must take. The route may cross long lengths of open fields, run along paved rural or urban roads, cross roads, ravines, rivers or lakes, or, more likely, some combination of all of these.

It could require buried cables, aerial cables or underwater cables. Cable may be in conduit, innerduct or direct buried, aerial cables may be self-supporting or lashed to outside plant fiber optics messenger.

Longer runs often include crossing water, so the cable may be underwater or be lashed across a bridge with other cables. GIS Geographic Information Systems Outside plant installations depend heavily on maps and data about the cable plant route.

This can include basic data on the local geology, locations of road, buildings, underground and aerial utilities, and much more.

It is beyond the scope of this book to examine GISs in detail but the designer should learn how to utilize a GIS to create the design to facilitate not only the design of the cable plant but also create documentation for the network.

It is important to understand the limitation of GIS. For example the type of ground along the route can determine the methods of underground installation, with deep soil permitting direct burial, other soils requiring trenching and conduit outside plant fiber optics rocky areas precluding underground installation of any type.

Aerial installations must be based on knowledge of the owners of the poles and the processes necessary to gain permission to use the poles and make ready for new cable installations.

Do not outside plant fiber optics GIS alone.

It is just one tool that can assist the designer but is not a replacement for traditional processes including site visits to evaluate the route.

Site Visits And as soon as outside plant fiber optics, you must visit the site or route where the network will be installed. Outside plant routes need to be driven or walked every foot of the way to determine the best options for cable placement, obstacles outside plant fiber optics be avoided or overcome, and to determine what local entities may have input into the routing.

Often cities or other governments will know of available conduits or rules on using utility poles that can save design time and effort.

For installations inside current buildings, you should inspect every area to be absolutely certain you know what the building really looks like and then mark up drawings to reflect reality, especially all obstacles to running cabling and hardware and walls requiring firestopping that are not on the current drawings.

Take pictures if you can. For buildings under construction, a site visit outside plant fiber optics still a good idea, just to get a feeling of what the final structure will be like and to get to know the construction managers you will be working with.


They may be the best source of information on who the outside plant fiber optics authorities are who will be inspecting your work and what they expect. With a good map. Creating a route map is the first step, noting other utilities along the route on that map, and checking with groups that document the current utilities to prevent contractors from damaging currently installed pipes and cables.

OSP installs are subject to approval by local, state and federal authorities who will influence heavily how your project is designed.
