CAN Bus Fiberoptic Router

CG FL

The CG FL CAN Bus fiberoptic router, fitted in a compact housing with integrated connector, transmits data between CAN subnets via optical fiber. It allows the realization of the high CAN data rates on the copper based segments while high system extension and short latency times are achieved at the same time.

CAN Bus Fiberoptic Router - CG-FL

The underlying technology offers the possibility to run the subnets on both ends at 1Mbit/s, earning the benefits of short reaction times and high data throughput.

Safety related control with SafetyBUS p is supported by the model SBR FL. This model has automatic baud rate detection and baud rate switching capability compliant with the SafetyBUS p standard.

Technical Data

Layout and Connection

CG FL has a male and a female D-Sub-9 connector to attach both CAN and power supply. The optical fibre is connected by a pair of ST plugs. 62.5/125µm or 50/125µm multi mode glass fibers can be used.

Limiting Values

Parameter Minimal Maximal Unit
Storage temperature -20 +80 °C
Operating temperature 0 +60 °C
Operating voltage (CG FL) -100 +30 V
Operating voltage (SBR FL) 0 7 V
