50ErAxx ytterbium fiber amplifier is designed based on telecommunication standard.enable realize catv 1550nm single-wavelength transmission, DWDM multi-wavelength transmission, gain flattened , low noise series (PA), the noise series (LA), amplifier series (BA ) to be choosen,focus on product design cost. it is the first choice transmission equipment to build large and medium-sized of 1550nmCATV economical fiber optic transmission network.
1550nm Erbium-doped fiber amplifier
15EAxx CATV erbium-doped fiber amplifier is mainly used for television image signals, digital TV, telephone voice signal and the signal of the data (or compressed data) optical fiber transmission over a long distance.It is the design according to the communication level standard, in terms of power, precision and high reliability.it is the first choice of transmission equipment to build a large and medium-sized 1550nm catv optical fiber transmission network.
1550nm Roman optical amplifier
Raman optical amplifier is a newly designed fiber amplifier based on stimulated Raman scattering (SRS) effect,Raman optical amplifier is considered as the core technology of new generation DWDM. WS-15RFxx series mainly used in fiber CATV system,extra-long trunk that is inconvenient for building relay station.relay station＞60KM,single span distance ＞80KM,DWDM extra-long trunk optical transmission system,submarine optical transmission system.
