An Optical Time Domain Reflectometer (OTDR) is commonly used for measurement of fusion splice loss. The basic backscattering principle makes the OTDR very sensitive to fibre MFD dependent light coupling properties. Its optimization requires a comprehensive approach encompassing material selection, process control, equipment precision, and. Splicing is required to create a continuous path for light transmission from one fiber to another. 1. This is part 6 of a tutorial on passive fiber optics from Dr. There are various possibilities: Mechanical splicing means that two fiber ends. With the building of Fiber- To-The Home (FTTH) networks and a general move from long-haul to access networks the average installed length of optical fiber cable is decreasing. Fibers can. This application note discusses the splice loss measurement technique and investigates the extrinsic and intrinsic factors a ecting the splice loss measurements when joining two bare fibre strands. In such situations, loss esti-mation is used to help.
