Name:Raman Fiber Amplifier       Model: RFA1550

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.
Description:
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).
RFA1550 Raman fiberamplifier adapts to G652, G655 and can be used in DWDM, CATV system.
