DVD-65C Fiber Optic Cable Assembly - IPC Training Home Page

DVD-65C Scriptpressure was applied when polishing with the coarse film – or that the connector was overpolished with the fine film.Fine polishing lines are typically acceptable. Small chips at the outer rim of the fiber are alsoacceptable. However, large chips in the center of the fiber are not acceptable and the fiber mustbe re-terminated.Another way of checking the fiber optic cable assembly is to perform a functional test. This isdone by plugging the connector into a mating connector that has a light source. The light source iscalibrated for the specific cable being tested and the cable is checked for acceptable signal lossmeasured in decibels. This test may be done on all the cables or just on the first few cables in aproduction run.Some fiber optic customers ask for a more extensive visual test using an interferometer. Theinterferometer graphically characterizes the quality of the polishing.This program has presented an overview of fiber optic cable assembly. First, you were introducedto the cables, the connectors and the tools used in fiber optic cable assembly, along withimportant safety considerations.Then we took a look at the assembly process – including preparing the fiber, injecting epoxy intothe connector and making the termination.The program concluded with a description of both machine and hand polishing, and the criteriafor inspecting and testing the finished cable.The quality of a single termination can effect the operation of an entire computer network, or anyother fiber optic cable application. Careful attention to every detail of the cable assembly processwill help to ensure that fiber optic connections work properly and reliably.6
