30~33dBm High Power Fiber Amplifier Module


YEDFA-CA-EM-B-XX series of high power fiber amplifier are especially designed for FTTx, CATV, FDC and HFC analog amplification applications that require high reliability. Compared to conventional amplifiers, these modules are more compact, powerful, stable and reliable.

Both input and output signals are sampled and monitored with a feedback circuit. ACC (automatic current control) and APC (automatic power control) circuits are designed into the amplifier to ensure high stability and reliability of output power. Based on integrated power monitoring circuit, this amplifier features RS-232 interface enabling connectivity with customer's control system.
