The module amplifies the 1550 nm optical signal, producing an optical output power of 19dBm. Equipped with WDM, it has one 1310 nm/1490 nm-input that multiplex the amplified 1550 nm-signal, providing one 1310 nm/1490 nm/1550 nm-output to be used in a GPON headend.
Based on YEDFA (Erbium and ytterbium doped fiber) technology, it provides a high gain, a higher optical power, and a low noise factor.
