Simplification is Our Innovation


Radiall's D-Lightsys brand offers a new family of products that support very short reach Free Space Optical communications (FSO). This unique solution is perfectly suitable for board-to-board, box to box or portable equipment communication. The F-Light design is compatible with misalignment tolerances above what electrical connectors typically offer.

The F-Light family of Free Space Optical transceivers (FSO) are specially designed for Board-to-Board, box-to-box applications where large misalignment and/or vibrations are critical. F-Light transmitters and receivers allow operating misalignment between two boards or boxes and are around +/-1mm and +/-1°. The devices feature a small footprint (8x8 mm) and are compatible with a bit rate from 100 Mbps up to 5 Gbps (a 10 Gbps version coming soon). Devices operate in the extended [-40;+90 °C] temperature range and consume less than 100 mW each.

Note: the design is compatible with automatic solder reflow and pick&place.

Main Free Space Optical applications:

  • Board-to-Board, box-to-box communication
  • Rotary Joint
  • Ruggedized portable/station contact-less communication
  • Displays
