Description:

SR812B optical receiver is our new development products that especially used in CATV network. The pre-amp adopts GaAs MMIC amplify module and the post-amp adopts GaAs power doubler amplify module .Support specifical attenuation and equalization inserts if you want.Or as per customer, adopts other module.With optimization design and plentiful technical experience that made this equipment with high performance specification. It is a ideal model for CATV network.
●PHILIPS, PHOTON or E-O PIN optical detector with high sensitivity are used as the part of photoelectric conversion; Import PHILIPS or MOTOROLA push-Pull amplifier module etc. with low noise are used as the forestage of RF amplifier; import PHILIPS or MOTOROLA RF multiplier amplifier module etc. are used as output stage. GaAs amplifier module will be used if you need.
●High responsible, with PIN photoelectric converter.
●High precision, with 10 cascade LED display the optical power.
●EOC head-end signal input interface is useful for Ethernet access.
●Optimization and typical circuit design, the pre adopts SMT process and the post adopts module amplify that made the photoelectronic signal transmission fluency.
●Power doubler output, high gain and low distortion.
●With AGC, when the input optical power range is -7~+2dBm, the output lever, CTB and CSO are keep constantly.Configure Chinese standard network management responder, easy access to the network management system.
