EDFA Card – DWDM Amplifier, 8-33 dB Gain, 20 dBm
The EDFA Card is a dual-amplifier erbium-doped fibre amplifier module with AGC and APC operation, 1528 to 1565 nm range and only 1/2 standard slot occupancy.
Description
Overview
The EDFA Card is the optical amplifier module of a DWDM system. It delivers a versatile, low-noise solution for erbium-doped fibre amplification in a highly integrated, compact module.
It operates with constant gain (Automatic Gain Control, AGC) and constant output power (Automatic Power Control, APC). The large-format module supports dual amplifiers with two independent gain units and occupies only 1/2 standard slot capacity.
