Optical data coupler LS682-DA-EN

The LS682-DA-EN is a device for serial transfer in Ethernet systems. One F1 and one F2 device is needed for each data transfer link. The physical transfer takes place protocol-free with 100 MBit/s full duplex. The data rate remains constant, irrespective of distance. Telegrams are not saved, which enables immediate transfer. The devices are optimized for conditions in factory automation.

Data is transferred in both directions by means of modulated light. The information at the input interface is modulated on the carrier signal. The information is then demodulated and issued to the output interface within the receiver.

Key series features:

  • Fast Ethernet optical data coupler
