Optical fiber amplifier (EDFA) is an important optical transmission device in 1550nm optical fiber communication system. This module uses imported high-performance erbium-doped fiber, low-noise pump laser and well-designed embedded automatic monitoring system to ensure the excellent index. Each EDFA module contains optical power detection components on input and output ports to automatically adjust the laser pump and keep the output power stable. The internal control circuit accurately maintains the output power and temperature of the laser; the parameters can be set and displayed through CMM management unit.
● Support hot swap.
● Optional CWDM.
● Optical power input and output status indicator.
● Adjustable attenuator for output from 0~4dB, 0.1dB stepping.
● Pump temperature, bias current, and cooling current are detected in real time.
● Wide input optical power range: -5 ~ +10 dBm.
