Optical Links

Modular 40 GHz Optical Link 

The Modular Link is a highly customisable wideband microwave optical link. The links utilise 1RU 19-inch rack enclosures, each housing up to four transmitter or receiver modules. The modules are configured to suit customer requirements and transmit/receive pairs feature flat gain response over frequency.


  • Frequency range up to 40 GHz
  • Flat frequency response
  • Up to 4 transmit/receive modules in each 1RU 19-inch rack enclosure

Four Channel Optical Link 

The Four Channel Optical Link is a wideband microwave optical link with a 40GHz bandwidth, suitable for antenna remoting and other applications. It caters for up to four RF inputs to the transmitter, each modulated onto an optical carrier across four separate channels. The receiver demodulates the four optical carriers to generate four separate RF outputs. This link uses external modulation for maximum dynamic range across the full 40 GHz bandwidth. Each channel of the link is fully isolated with separate laser, modulator and photodetector. The receiver module can be battery operated to allow for use in remote locations.


  • Frequency range 0.5-40 GHz (2-20 GHz option also available)
  • Flat frequency response
  • Low spurious output
  • Independent channel control and monitoring
  • 1U 19-inch rack mount transmitter module
  • Compact receiver module, only 271 mm x 257.4 mm x 102.6 mm
