4.1
Use and Application
The optical data coupler serves as an optical link between two Ethernet devices;
ideally, one of these devices is mobile. The opening angle is optimized for
operations in high-rack storage.
Devices in industrial Ethernet networks (e.g., with PROFINET, EtherNet/IP, and
other Ethernet protocol designs) can be connected to the optical data coupler.
The physical transfer takes place with 100 MBit/s full duplex. The connection to
multiple devices must be implemented using switches that have been certified for
use with the bus system in question. All layer 2 telegrams (IEEE 802.3 Clause 25)
are physically transported. There is no saving of telegrams, so the transfer is not
delayed at all.
Devices with a transfer rate of 10 MBit/s can be connected via a switch.
The optical data coupler uses a semiconductor laser as an optical emitter. The
dilation of the light beam and the use of return map blocks guarantee that the
devices are harmless in accordance with laser class 1M. The emitted beam must
not be viewed with telescopes or binoculars from distances of less than 20 m. At
longer distances, the limit values for laser class 1 are not exceeded, even when
viewed through a telescope with a 50 mm aperture.
