1,Overview
OS-EDFA04(W) is Ytterbium and Erbium Doped Fiber Amplifiers (YEDFA) that designed for using in CATV,FTTX and HFC application. It is optimized for 1550nm wavelength and is packaged in a 1U 19 inch rack housing. The product is flexible enough to perform all the requirements of CATV,FTTX and HFC applications. The device chooses a high performance PUMP laser and circuit (include ACC and APC) and optical output power is adjustable and flexible for network link loss budget. It with WDM products also provide monitors and associated aplay &Web or remotely via Ethernet based-SNMP NMS. The device also support multiple optical output by build-in PLC splitter, which minimizes the investment cost.
