CAN Bus (Controller Area Network) is commonly used in various vehicles, automobiles, and industrial automation applications. CAN Bus allows microcontrollers and attached devices to communicate with each other in applications without use of a host computer.

Use of fiber optic repeaters allows electrical isolation between nodes of a network and attached devices, protecting them from electrical surges and providing EMI/RFI immunity. Use of fiber also allows for longer distances between nodes when required. (Observe network turn around timing restrictions)

Electrical isolation provides the benefits of EMI/RFI immunity, electrical surge immunity, less impedance problems and elimination of crosstalk.

UL Listed. Meets FCC requirements of Class A, Part 15 Computing Devices Standard.
