The product is a high output power C-Band Er-Yb co-doped double cladding optical fiber amplifier. The individual optical design ensures the perfect performance: adopt high stable and high precision CPU system to ensure that 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). And the GPON ports are compatible with the XGPON1 and OTDR wavelength to suit multiple application scenarios.
