DW-OROA Series outdoor optical receiver is a high-grade type four output CATV network optical receiver, the various working parameters are controlled by a microprocessor, the optical power, intuitive display, fixed attenuation insert. Optimized circuit design, professional RF chip RF attenuation, attenuation and balance of good linearity, high precision. Imported PHILIPS or NEC high gain amplification of light module, AGC control characteristic, output settings, optical power input ( – 7 ~ + 2 dBm ), CTB / CSO basically unchanged, single-chip microcomputer to control the machine work, machine reserved for data communication interface, convenient and network management responder connection, access network management system, the digital display parameter, make engineering debugging more convenient, is the mainstream model of constructing CATV network. The cast aluminum shell, high reliability of switch power supply, strict anti-lightning system, to ensure that the equipment can work stably for a long time in the wild environment.
