flexopto - Best-in-class flexray, can and lin to fibre-optics converter for emc, isolation and range extension applications

DRIVING T H E MOBILITY OF TOMORRO W


FlexOpto is a bidirectional media converter which transmits electrical FlexRay, CAN or LIN signals via optical fibre. For an independent use, a high capacity lithium ion battery allows an operation up to 40 h without charging. The PCB design is optimized for EMC tests, emits very little noise and is unsusceptible against high levels of electromagnetic noise.

emC testing

FlexOpto

FlexOpto has a PCB that is optimized for EMC testing. Operating on internal, a rechargeable lithium ion battery, it can transmit the
