Linear Erbium Doped Amplifier (EDFA)
Amonics’ specialist products, Erbium-doped Fiber Amplifiers(EDFA), are made with high power pump laser and high stability pump combiners, robust in high power boosting. The result are EDFAs that possess high output power, linear gain with very low noise, and are ideal for high power EDFA applications. The turnkey microprocessor controlled benchtop EDFAs manage alarms and status indicators. An integrated RS232 computer interface enables easy control, diagnostic functions and data acquisition. The benchtop EDFA series consist of different type of EDFAs for various applications such as general purpose, pre-amplifier, booster, in-line, polarization maintaining, C+L band amplification.
