DWDM EDFA Module
1. Description:
DWDM EDFA modules are designed for long distance DWDM communication systems. With gain flattening filter (GFF), EDFA offers constant flat gain for multi-channel DWDM systems, The EDFA works at C-band(1528 to 1603nm) or L-band (1570 to 1604nm), integrates electric driver, remote control, temperature control, and alarm circuits all together in a small package. The EDFA has assembled up to three pump lasers to meet the different output power levels required by DWDM systems and protect the pump failure.
2. Features:
* High reliability
* Flat and broadband gain
* Pump failure protection
* Automatic gain and output power control
* RS232 remote control connector
* Customer friendly software
* Single 5 volt power supply
* Compact package
3. Applications:
* DWDM communication system power amplifier, in line amplifier and pre-amplifier( C-band or L-band)
