CU1561 | EtherCAT media converter plastic optical fibre

The EtherCAT-capable CU1561 for Industrial Fast Ethernet/100 Mbaud serves as media converter from POF (plastic optical fibre) to copper and vice versa. The CU1561 is suitable for POF cables, which are particularly easy to install in the field.

The CU1561 always operates bidirectionally and collision-free with constant delay. It can be diagnosed as a separate EtherCAT device. In this way, unlike standard media converters, the CU1561 enables fast link control and the safe closing of the EtherCAT strand even in the event of a fault. Since the transfer direction (copper to optical fibre | optical fibre to copper) is relevant for the bus, the device can be configured via a switch. Via this switch “Link Loss Forwarding“ for normal Ethernet operation can also be selected.

The CU1561 is useful in applications where higher EMC loads on the bus line are to be expected or where simple assembly is required.
