Raman Fiber Amplifier

Model: RFA1550
RFA1550 series Raman fiber amplifier adopts high performancepassive device and 14XXnm pumping laser. Gain medium uses the fiber opticaltransmission cable, so tHFA1550t the signal light in fiber transmission at thesame time can be larger, then to improve the line's optical signal to noiserate(OSNR).

Features :       
◇Low noise figure, flatgain.
◇Adopts famous Japan brand"Fitel" raman pumping laser.
◇Perfect laser APC, AGC and ATC controlto ensure the laser's long working life.
◇The variety of raman switch gains canbe chosen, it can adapt to different network.
