NY048 Series Multifunctional Optical Transceiver

  • Fiber and cable are used as carriers to achieve RF signal transmission, status signal and control signal transmission, Ethernet communication, etc. between the central computer room and outdoor radar terminal equipment in the satellite system.
  • Consists of an indoor unit and an outdoor unit, completing the uplink and downlink full duplex transmission of L-band RF signals. The uplink is for controllable transmission of a 10 MHz clock signal, which can realize the real-time display of work status and recording and reporting of fault status. The downlink is used as an adaptive bidirectional Ethernet communication interface of 100M/1000M.
  • NY048 Series adopts a modular design. Each functional module adopts independent chambers to reduce interference between modules. The overall closed design of metal materials effectively prevents external signal interference and insulates signal leakage from interfering with other devices.
  • Waterproof functions on the installation surface.

Attachment


Feature

  • Transmitting Analogue and Digital Signal
  • WDM (Wavelength Division Multiplexing)
  • High Reliabilit
  • Strong Anti-interference Ability

Application

  • Ground receive station of satellite system
  • Radar system
  • Mobile communication terminal

NY048 Series Multifunctional Optical Transceiver uses optical cables as the long-distance transmission medium for signals. Compared to traditional cable transmission, optical cable transmission has advantages such as wider bandwidth, stronger anti-interference, better confidentiality, lower system power consumption, and lighter weight. Not only can it be used for communication between radars and base stations in traditional radar ground stations, but also for communication between radars and signal processing centers in mobile or vehicular stations. After a portable upgrade, it can also be used in mobile radar communication systems.
