Standard EDFA

Erbium-doped Fiber Amplifiers (EDFAs) are our core products. With years of experience on design and products, our EDFAs excel in stability, reliability and robustness. They have excellent track records with happy users around the world and enjoy huge success in various applications. The EDFAs feature high output power, high gain with very low noise, and they can be customized to accommodate a wide range of input signal levels.

The turnkey microprocessor-controlled EDFAs provide illustrative alarms and status indicators. An integrated RS232 computer interface enables easy control, diagnostic functions and data acquisition. All EDFAs are available in both benchtop and rackmount casings.
