Televes YEDFA Optical Amplifier with WDM – 769611
Description
1550 nm, Po 20dBm
This device consists of an amplifier and a WDM. Designed to mix the RF Overlay service with GPON.
The optical amplifier amplifies a 1550nm optical signal, with an output power of 20dBm. 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 32 x 1310 nm/1490 nm-inputs that multiplex the amplified 1550 nm-signal, providing 32 x 1310 nm /1490 nm /1550 nm-outputs to be used in a GPON headend (usually OLT).
Highlights
- 20 dBm high-optical output power amplifier
- Equipped with WDM for the multiplexing of RF Overlay with GPON signals
- -10 dBm to +10 dBm input range
- Status LED indicators
