Fibre Optics Connectivity
Fibre Optic is the fastest, most reliable network data transfer solution available to business and is ideal for connecting branch offices or businesses that have high bandwidth requirements, such as voice, data and video. Even though fiber optic cables may look like traditional copper cables, we should always keep in mind that inside fiber cables are fragile glass fibers which can be broken easily if not properly handled.
During any Fibre optic cable installation project, we must keep two very important things in mind: First, never over-bend the fiber cable over its minimum bend radius. Second, never pull over the cable manufacturer’s cable pulling tension specification. Fiber cables all have a minimum bend radius specification by the manufacturers. This the minimum curve radius while bending the fiber cable in either installation process or after the installation in its final resting position. You can make larger curves but never smaller than specified.
It is the fiber cable bend radius specification during a cable pull as in the installation process. The cable must not bend tighter than its loaded MBR at any time during the installation process. Loaded MBR is larger than unloaded MBR as explained below. It is the fiber bending radius specification in the cable’s final resting position after installation. That is when the cable is not under any tension. Often, this spec is determined by a simple multiplication such as 15~25 X OD (fiber cable outside diameter).
Fiber optic cables are composed of individual fibers (strands). Individual fibers also have a minimum bend radius specification, which is usually 2~3 cm and is much smaller than jacket cables. Bending a fiber cable over its MBR is one of biggest factors in fiber damaging in fiber cable installation projects.
This practice can either break the inside fibers or increase fiber attenuation (fiber power loss) over the manufacturer’s specification. Even if the inside fibers are already broken, you may not see any physical damage to the outside jacket at all. The consequence is, you have to replace the whole section or even the entire length of cable. As a good practice, all fibers need to be thoroughly tested after cable installation.
Pulling tension is the force placed on per square unit of fiber cable cross section. Maximum pulling tensions during fiber cable installation are specified by cable manufacturers and should not be exceeded at any time. Most tensile load on a cable will occur in a vertical installation and is caused by the cable’s own weight.
Fiber optic networks are put into service by many different types of telecom providers, for example cable businesses, telephone service providers
and companies providing connection to the Internet, and are employed in the central networks of these companies.
