The following specification is the fiber testers and specification for a cable before delivery. 1. Optical Time-Domain Reflectometer (OTDR) — sends a laser pulse through the fiber and detects the return signal strength as well as the transmitting time. This test shows the overall character of the fiber strand including splice loss, splice numbers, connectors, […]

ITU T G 652 Fiber Link Design consideration
A concatenated link usually includes a number of spliced factory lengths of optical fibre cable. The requirements for factory lengths are given in clauses 5 and 6. The transmission parameters for concatenated links must take into account not only the performance of the individual cable lengths but also the statistics of concatenation. The transmission characteristics […]
