LOSSLESS OPTICAL COMPONENT

摘要

A lossless optical component (2) includes having an input and at least one output. The optical component (2) comprises an operational portion (2b) and an amplifier portion (2a) upstream of the operational portion. The amplifier portion (2a) includes an optical amplifier (6) for amplifying optical signals received by the input. The optical amplifier (6) is provided with input optical wave guiding means (8) via which the optical amplifier is optically pumpable by a remote pump laser (8). The output of the optical amplifier (6) is proportional to the loss of the operating portion (2b) of the optical component (2).
