OPR-2108GK FTTB AGC RFoG Optical Receiver
   Content
OPR-2108GK optical receiver is the latest 1GHz Bidirectional FTTB optical receiver. Integrated with RFoG burst mode transmitter module in return path, it is featured with wide range receiving optical power, high output level and low power consumption. It is the ideal equipment to build the high-performance NGB network.
 
 
Features
1) Excellent optical AGC control technique, when the input optical power range is -9~+2dBm, the output level, CTB and CSO basically unchanged;
3) Built-in high reliability low power consumption power supply, and selectable external power supply(DC12V)

Note 1: Configure 59 PAL-D analog channel signals at the 550MHz frequency range. Transmit digital signal at the frequency range of 550~862/1003MHz.
The digital signal level (in 8MHz bandwidth) is 10dB lower than analog signal carrier level. When the input optical power of the optical receiver is -1dBm,
the output level: 108dBμV, EQ: 8dB.
