8-output YEDFA optical amplifier with WDM and double power supply
1550 nm, Po 20dBm
This device consists of an amplifier, a WDM, and a double power supply. Designed to mix the RF Overlay service with GPON and simultaneously power the OLT.
The optical amplifier amplifies a 1550 nm optical signal, with an output power of 20 dBm. Based on YEDFA (Erbium and ytterbium doped fiber) technology, it provides a high gain, a higher optical power, and a low noise factor.
Equipped with WDM, it provides eight 1310 nm/1490 nm-inputs that multiplex the amplified 1550 nm-signal, providing eight 1310 nm /1490 nm /1550 nm-outputs to be used in a GPON headend (usually OLT512).
Finally, the hot-swappable double power supply feeds an OLT.
