🗗 EDFA Buyers Guide
Lightwaves2020 has released one compact variable gain EDFA module with low noise figure. With Lightwaves2020’s proprietary Liquid Crystal Variable Optical Attenuator and Thin-film based Gain Flattening Filter, the variable gain ranges from 15dB to 25dB within a wide input power range. This makes the module suitable for pre-amplifier, inline and booster applications. Our products achieve gain deviation < ±2dB & noise figure <7dB over all operating conditions. This compact full-function EDFA module covers all automatic control modes for constant gain, power and current. Monitoring of input, output and reflected signal levels as well as temperature and signal levels alarms are provided. Custom products are also available.
