1550 nm EDFA Module

Part Number:



The LB-1000-EDFA series is a family of high performance EDFA modules. This EDFA module is an integral part of the high density LB-1000 headend platform. The LB-1000-EDFA module uses a high quality 980 nm and 1480 nm pump laser, high amplification gain with low noise figure, and a wide range of optical output powers (15 dBm to 23 dBm). The LB-1000-EDFA module is an ideal solution for both analog and digital signal transmission. The built-in microprocessor can detect and monitor the pump laser status and the input/output optical power in real time. When the operating status of the EDFA is abnormal, a corresponding alarm will be triggered. In the case of a critical alarm, the pump laser will be shut down automatically to protect the EDFA. If there is no optical signal in the input, the module will turn to standby mode automatically. Module parameters can be monitored and configured through the LB-1000-CM system management control module using the touch screen or by using the PC (web GUI or SNMP agent).


  • Wide range of optical output from 15 dBm to 23 dBm
  • Hot-swappable capability
  • -6 dBm to +10 dBm optical input range
  • Low noise figure & high optical output stability
  • Optical output can be adjusted
  • Automatic power/current control mode (APC/ACC)
  • Dual pump laser design
  • Built-in microprocessor monitors performance of the EDFA
  • Local or remote monitoring using the LB-1000-CM system management control module touch screen, web GUI or SNMP
