Optical transmission Unit For Can FD and Flexray™
The CW-131FD Optical Transmission Unit provides bidirectional optical transmission of automotive network data over distances - up to 500 m. Overall, it is possible to connect 4 CAN FD/HS (flexible datarate/highspeed), 2 CAN LS (lowspeed) and 4 FlexRay™ (channel A and B) buses.
Hereby, CW-131FD operates as an active CAN node to guarantee proper transmission, even when used outside specified cable length restrictions. CAN-bus settings can be configured by a webbased configuration software, accessed easily via ethernet connection. FlexRay™ transmission starts up instantly and ensures deterministic timing - plug-n-play.
All bus data is transmitted via a fiber optic cable (FOC), comprising 4 fibers. Due optical transmission best galvanic isolation and noise immunity is provided for connected devices.
CW-131FD system runs stand-alone and consists of two identical TX/RX units interconnected via fiber optic cable. It is primarily designed to exchange data between two distant located test bench systems - e.g. hardware-in-the-loop simulator systems. Therefore, CW-131FD features a 19” rack housing ideal for most test bench applications. Moreover, it is well suited for testing purposes in an EMC chamber, too.
