1,Overview
OS-EDFA04 which is Ytterbium and Erbium Doped Fiber Amplifiers (YEDFA) 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. The EDFA-04 also provides monitors and associated alarms for all vital characteristics. The status and management of the device can be monitored and managed either from the LCD front panel display &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.
