Product Summary   

WR1002RJL

 is our latest high-end two-way output CATV network optical receiver. The pre-amp 

adopts  full  GaAs  MMIC  amplify  module  and  the  post-amp  adopts  GaAs  amplify  module. 
Optimization  circuit  designs,  coupled  with  the  company  10  years  professional  design  experience, 
make  the  equipment  achieve  high  performance  index.  The  parameters  will  be  displayed  by 
singlechip to make the engineering debug more convenient. It is the best choice for CATV network.
