    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.
    Termination classroom 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.
