High Reliability 33dBm YEDFA Fiber Amplifier Module

Description

This line of high power fiber amplifier combiners features a dual stage amplification configuration, pre-amplifier and power amplifier and the use of select multi-channel splitters with extremely low IL and high reliability.

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. Standard user-friendly RS-232 interface enables reliable connectivity with customer’s control system.

Features
