The product is a high output power C-Band Er-Yb co-doped double cladding optical fiber amplifier. A proprietary ATC (Automatic Temperature Control) and an APC (Automatic Power Control) circuit ensure the high stability and reliability output power, and the unique optical circuit design ensures the excellent optical performance. The high stability and high precision MPU system ensure the control, adjustment and display are intelligent and user-friendly. The product can realize different service wavelength (GPON/XGPON1/OTDR and CATV) multiplexing in FTTX network to maximize the value of optical distribution network (ODN). To suit multiple application scenarios, the GPON ports are compatible with the XGPON1 and OTDR wavelength.
