Description

CAN fiber optic router SBR FL, fitted in a compact housing with integrated connector, transmits data between CAN subnets via optical fiber.

It allows the realization of high CAN data rates on the copper based segments while high system extension and short latency times are achieved at the same time.

The underlying technology offers the possibility to run the subnets on both ends with 1000 kbit/s, earning the benefits of short reaction times and high data throughput.

SBR FL has safety related control with SafetyBUS p with automatic baud rate detection and baud rate switching capability compliant with the SafetyBUS p standard.

Technical Data

Layout and Connection

SBR FL has a male and a female D-Sub-9 connector to attach both CAN and power supply. The optical fiber is connected by a pair of ST plugs. 62.5/125 µm or 50/125 µm 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
Voltage on CAN bus connections	-30	+30	V

Any (also temporary) stress in excess of the limiting values may cause permanent damage on CG FL and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.
