27dBm High Power Fiber Amplifier Module

The YEDFA-CA-EM-A-27 fiber amplifier series are specially designed as highly reliable amplifiers for FTTx, CATV, FDC and HFC analog applications. Compared with conventional amplifiers, these modules are more compact, powerful and have higher reliability and stability.

Both input and output signals are monitored with a feedback circuit. ACC (automatic current control), APC (automatic power control) and AGC(automatic gain control) circuit are employed in the amplifiers to ensure the high stability and reliability of output power. An EVOA is built in to extend output power to -3dBm. Integrated power monitors inside enable ease of operation via the featured RS-232 interface linked to customer’s control system. Key Feature: Gain fiber is encased inside a hermetic sealed package.
