FLY 1000R Series Optical Transform Unit is a high performance, low-power optical transmission system unit, mainly for optical regeneration, re-amplifying, re-shaping the signals in the transmission process. It can save optical fiber resources and networking cost effectively, and solves the problem that the transmission distance is too long to transmit. With advantages of small volume optical signal, economy and safety, convenient construction and etc., it is widely used in various optical transmission fields and long-distance trunk transmission.
