27-30dBm High Power Fiber Amplifier Module


The YEDFA-CA-EM-C-XX fiber amplifier series are highly reliable amplifiers especially designed for FTTx, CATV, FDC and HFC analog applications. Compared with conventional amplifiers, these modules are more compact, powerful, and have higher reliability and stability.

The high power fiber amplifiers are based on two stage amplification configuration, pre-amplifier and power amplifier. Both input and output signals are monitored with feedback circuit. ACC (automatic current control), APC (automatic power control) and AGC (automatic gain control) circuits are employed to ensure high stability and reliability of output power. Integrated power monitors inside enables ease of operation via the featured RS-232 interface linked to customer’s control system.
