The Summary of Different Finished Fiber Optic Cables Installation

Posted on by FS.COM

Fiber optic cable installation is a very special task, because fiber optical cables can be easily damaged if they are improperly installed. It is imperative that certain procedures be followed in the handling of these fiber cables to avoid damage and/or limiting their usefulness. Only a trained professional can achieve rapid and accurate.

Finished fiber optic cables can be categorized as outdoor cables, indoor fiber cables, or indoor/outdoor cables (shown as the following figure). However, most of the technology of optical fiber cable installation has been borrowed from those used in copper cable. And at present most of the fiber cable contractors from copper network background.

Most independent fiber cable installation contractors install indoor cables most of the time. Indoor fiber cables are mostly used as the backbone for campus networks, enterprise LAN systems and etc. And there is the submarine cable category. They are laid from ships built for that purpose. They are only used by the big global network backbone builders. But actually there are many small divisions within each group. When installing optical cable, what you don’t know could really hurt you or damage your cable. there are many different types of finished fiber cables installations knowledge we need to know, let’s examine them one by one.

1. Submarine cables. Laying of submarine cables are the purpose of shipbuilding. They were buried at the bottom of the ocean trench depth of less than 200 meters. Areas in the deeper level, submarine cables laid directly at the bottom of the sea.

2. Direct-buried fiber cables. Direct-buried cables are also called armored cables. They have aluminum foil wrapped around for mechanical protection from rodent bite and outside forces. They are laid in a deep trench dug with a cable plow and then covered with dirt.

3. Outdoor cable does not include the buried cable, cable duct is necessary. Cable ducts are plastic tubes which provides a path and protection for outdoor cables. They are buried in the trenches, and then covered with dust. Cable ducts have various size and flexibility, they can be from 1 inch to 6-10 inches. Some of them are flexible and others are very strict.

4. Cable ducts are buried first without any fiber cables inside. They can be routed directly between two endpoints or through a series of access points at manholes.

5. Outdoor cable through the cable duct and traction on the rope. Pull on the rope attached to the strength of the member, and then pull out the cable of the destination. You should not put the fiber directly because it will break easily and result in a broken cable is useless to you.

6. And then there are aerial cable. One type of aerial cable with a messenger line to provide mechanical support and they can hanged on poles without any lashing. This type of aerial cable is called figure 8 or self-supporting cable. Other types of aerial cables have to be lashed with a special lashing wire running around both the cable and the separate messenger wire.

7. Indoor cables can be installed within walls, through cable risers, or elsewhere in buildings. Note: only special under carpet fiber cable should be used for laying on the floor where people walk.

8. A special type of indoor cable is called plenum cable. They have special formulated out jacket material for fire rating. Only plenum cables can be used in air return spaces for the VAC system.
