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).
Model: HFA1550
As the all opticalnetwork's spread, especially FTTH construction high-tide's coming, ultra-highpower fiber amplifier will play an increasingly important role in all opticalnetwork process continuously to extend and expand. HFA1550 series fiberamplifier adopts multi-mode pumping laser and double-clad Erbium/ Ytterbiumco-doped technology, which makes fiber amplifier output power up
