27-33dBm HP PM Fiber Amplifier Rack


YEDFA-PM-SO series of high power polarization maintaining fiber amplifiers are designed to output optimal optical performance with high reliability and stability. These amplifiers are especially developed for PM transmission, sensors and LIDAR applications.

This line of PM high power fiber amplifiers features a dual stage amplification configuration, pre-amplifier and power amplifier, the use of selected components with extremely high PER and low EL values, and the careful management of splice joints to preserve polarization.

Both input and output signals are sampled and monitored with a feedback circuit to protect the amplification system. APC (automatic power control), AGC (automatic gain control) and ACC (automatic current control) circuits are designed into the amplifier to ensure high stability and reliability of output power. Standard user-friendly Ethernet or RS-232 network interface enables reliable connectivity with customer's network management system.
