17dBm Erbium-doped Fiber Amplifier Rack


EDFA-PM-SO series of Polarization Maintaining Fiber Amplifiers are designed to output optimal optical performance with high reliability and stability. These amplifiers are especially developed fro PM transmission, sensors and LIDAR applications.

This line of PM fiber amplifiers features a single stage amplification configuration. The use of the selected components with extremely high PER and low EL values, and careful management of splice joints preserve polarization. Both input and output signals are sampled and monitored with 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 stability and reliability of output power. Standard user-friendly Ethernet ot RS-232 network interface enables reliable connectivity with customer's network management system.
