Lesson 7: Splices And Terminations

How are fiber optic cables spliced or terminated?
Objectives: From this lesson you should learn:
The difference between terminations with connectors and joints with splices
Should you use connectors or splices?
Requirements for splices and connectors
Splice types
Splicing procedures
Connector styles
Termination types of connectors

In this lesson, a long and very important one, you will learn about fiber splicing and termination. Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear. Either termination method must have two primary characteristics: good optical performance indicated by low loss minimal reflectance and high mechanical strength.  Terminations must also be of the right style to be compatible to the equipment involved and be protected against the environment in which they are installed.

Generally, OSP focuses on splicing, either for joining cables or attaching pigtails for termination. The termination processes described in the materials are rarely used in OSP applications but should be understood by all techs.
