Optical coupler for CAN data transmission

The PCAN-LWL package enables any CAN section to be replaced by an optical waveguide. The optical waveguide consists of a 62,5 / 125 μm duplex fiber optical cable with ST connectors. Conversion can be to high speed CAN or low speed CAN.

Areas of application include EMC measurements on CAN modules, CAN sub-sections with high electromagnetic irradiation and lines through areas protected against the risk of explosion.

The package supplied contains two modules complete with five meters of fiber optical cable including connectors. The modules require an external power supply and have a built-in power pack. They can also be powered by batteries.

A suitable battery is available as an option.
