Indoor optischen Knoten

Indoor optical nodeis bidirectional design, HFC transmitting products. Modulization plug-in design, collocate according to customers requirements. Add return path can update as bidirectional Optical Workstation. Use two way RF-signal amplify, GaAs amplifier module(front-positioned) give superlow noise and low Optic power receiving. Two output or four output. The maximum Output level is 112dBμV(0dBm input optical power). Every outputp point can be used as return path signal input point. Features:(1) Use optical receiving module.(2) Receiving Optical Wavelength 1290 1600nm.(3) 1000MHz design, (750/862MHz).(4) Plug-in bidirectional filter:30/47MHz 42/54MHz 65/87MHz optional.(5) GaAs amplifiermodule(front-positioned) give superlownoise and low Optic power receiving.(6) Two-way individual amplify .(7) With Automatic temperature compensation .(8) 5-200MHz return path, enlarge network function.(9) Input signal level can adjust individual.(10) Ruturn path can use at any time and updateNetwork.(optionVRT-200X/P Return transmitter)(11) With optical power monitor(LED).(12) Power supply: 60V/AC and 220V/AC optional.(13) SMPS and with wide range of voltage.Electonic Parameter:Frequency range 45 750/862MHzFlatness in band± 0.75dBReturn loss≥ 16dB(45 750MHz)≥ 14dB(750 862MHz)Nominal output level112dBμVMax.
