In such cases, some attenuation is required to prevent this problem. This attenuation is usually covered by:
❑A moderate link length
❑The fiber optic connectors
Splicing
Many fiber optic installations employ the use of patch panels to manage expansion and topological changes. A typical patch panel consists of a set of
If a fiber optic cable breaks, the breakis usually fixed by splicing the broken ends together. Use one of the following types of splicing:
❑Fusion - A fusion splice usually offers lower power loss, but the fusion equipment is often bulky and costly.
❑Mechanical - A mechanical splice can be conveniently used in the field when a fusion splice is not available. If a repair is made, make sure that the fiber cable still meets the power loss guidelines.
