SDH EDFA is specially designed for transmission system.High stable Pump Laser and unique ATC(automatic temperature control) and APC(automatic power control) circuit are employed to ensure high stability and reliability of output power.Rack-Mounted erbium-doped SDH EDFA fiber amplifier series have the characteristics of low noise figure,wide input power,tunable output power and high reliability,compatible with 1.55 um digital signal optical fiber cable transmission system.It also includes RS-232 computer interface.
SDH EDFA rack-mounted for transmission system is erbium-doped fiber amplified.Rack in the built-in microprocessor for real-time monitor for pump working status and input/output optical power.When the optical fiber amplifier work disorder,it outputs the corresponding alarm.A serious warning will automatically shut off in order to protect the pump laser amplifier.The input light will automatically turn off the pump when inputting matt.This function can also be shielded through software.The unique optical design for optical fiber cable ensures the excellent optical performance.The high stable and high precision MPU system ensure the control,adjustment and display are intelligent and easy.
