Performance Characteristics

  • Operation Frequency Range: 40-860MHz. Single Directional network transmission, dedicated for the indoor CATV using.
  • Adopt Philips, Photon and E-O Pin Optical Receiving IC, import Philips or Motorola power double amplify module (or depends
         on customers, adopt GaAs )
  • Plug-in insert return reverse transmit parts, could develop the return access conveniently.
  • Insert Dual-Filter, insert Fix-Equalizer, Fix Attenuator insert output splitter, eighth-order optical power indication, reasonable
          testing connector, make more convenient.
  • Aluminum waterproof housing, high-capability power switch, anti-thunder system, make sure work properly outdoor.
  • Work properly under low-optical power 9dBm. High performance to price ratio, be suitable for medium and small size CATV
          network.
