IXXAT CAN-CR210 - CAN Fiber Optic Repeater with Backbone bus: F-SMA Connector

The Ixxat CAN-CR210/FO repeater with 2 CAN interfaces, one of which is a Fiber Optic interface, enables the conversion of CAN signals from copper wire to fiber optics. This conversion enhances connectivity in high-electromagnetic interference zones and provides the flexibility to optimize network structures. It has an integrated CAN backbone interface. 

Designed for industrial environments, it meets high demands for robustness, temperature ranges, and safety and has minimal impact on real-time behavior, equivalent to a short line length (ca. 60 m/300 ns delay). With transparent transmission, the device is compatible with all higher layer protocols.

Fiber Optic Interface

Fiber optic ensures uninterrupted data transmission in high-electromagnetic disturbance zones, enabling enhanced connectivity for critical applications and high performance. There are 2 options for the Fiber Optic Interface connection: F-SMA or ST .

System Reliability

System reliability is ensured by electrically isolating CAN segments and power, auto-separating network faults, and keeping the network operational. In case of disturbances in the CAN lines, the repeater automatically disconnects the affected segment and restores it after the fault is resolved, ensuring uninterrupted network operation. Integrated bus termination resistors (120 Ohm, switchable via DIP switch) prevent reflections on the line ends and ensure optimum communication.

System Protection

Using the CAN-CR210/FO, network components can be galvanically isolated up to 1 kV. This reliably enhances the protection of the device against damage to electronics caused by voltage peaks. The 2 CAN channels can be used to establish a physical coupling and galvanic isolation of two segments of both CAN bus systems.

Network Design

The CAN-CR210 helps to optimize CAN network structures by enabling extended layouts (stub lines, star and tree topologies).  These optimized topologies enable simpler wiring, resulting in less cables and cost savings at installation and maintenance. To achieve tree or star topologies, multiple repeaters can be easily connected in series through the integrated backbone bus.
