FTTH Optical Receivers

Introduction:

-          Features

 

1. High receiving sensitivity Pin=-21dBm, MER>=26dB

2 .Optical input range: PIN=-21dBm- 0dBm

3. Saving Optical power and lower down network costs

      4. Good flatness in 47-862MHz(FL<= +/-0.75dB)

      5. Metal housing for better protection purpose of optical components

      6. Low power consumption, good reliability

 

-          Application

 

       1. FTTH network

       2. FTTH PON
