      Description:

      Based on plenty of experience about CATV HFC network optical fiber transmission equipment, we developed SR802, SR802B, SR804, SR804B series field optical receiver which is two-way optical receiver; They are mainly used in long-distance optical fiber transmission of TV image signal, digital TV signal, telephone voice signal and data (or compressed data) signal. We are innovating the product technology, rebuilding the line structure and Improving the process quality since we developed the first CATV optical receiver successfully in 1995; The current WR series optical receiver are not only of the lead position in domestic level regarding line technique, but also the same as imported product regarding technological quality; We have developed a variety of different models for users to choose models.

      ●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.
      ●Built-in add-in (reservation) reverse return optical transmitter component are useful for open reverse return channel.
      ●There are plug-in duplex filter, plug-in fixed equalizer, fixed attenuator, plug-in output splitter, eighth order optical power indication, scientific and rational line detection port in it to make it more convenient to debug.
      ●There are cast aluminum waterproof housing, switching power supply with high reliability, strict anti-lightning system to ensure it can work steadily in the field.
      ●Configure Chinese standard network management responder, easy access to the network management system.
