20dBm Mini Size EDFA Module


Compact Mini Size EDFA Module is designed for optical communication and CATV systems. It can be used as a power amplifier, in-line amplifier or pre-amplifier based on system architecture. It features stable output power, low noise and power consumption. Compact footprint makes it easy to be installed where it is needed, adding to flexibility in network design. To achieve high performance, world brand pump lasers and erbium-doped fibers are used; optical isolators are added at both input and output.

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