Termination and splicing are used in certain applications and
need to be explained in the context of those applications. For most installers, installing
connectors is only a concern for multimode fiber in premises applications, while splicing is primarily used with singlemode
fibers in outside plant applications, due to the longer length of most singlemode outside plant networks and the
common practice of splicing terminated pigtails onto singlemode fibers instead of directly
connectorizing the fibers.
training should include understanding where and why connectors are
used, how they are constructed, factors that influence loss, what styles are available and which
are most popular. Comprehensive coverage of the various methods used to terminate them (epoxy
polish, hot melt, crimp/polish, stub fiber, etc.) is very important.
Likewise splices types, cost tradeoffs as a function of volume,
and equipment necessary should be explained. Besides the differences in
mechanical and fusion splicing, the difference between single fiber and
ribbon splicing is important for students to know.
Hands-on training in the following lab session should allow
each student to install several connectors, preferably of various
types, so the classroom should include information on these types.
Splicing techniques should be covered in detail whether or not all
types are included in the lab.
Advanced courses which allow hands-on termination of a larger number of
connectors and/or splices are recommended for all serious installers, especially for advanced FOA certifications.
