Using the Ethernet Optical Transceiver
An Ethernet connection is made to each Transceiver at the respective D-connector on the rear of the
ViaLite
19” rack chassis, via the RJ45 to D-connector adapter cable together with the RJ45 coupler.
Two fibre optic cables are necessary for the operation of the Ethernet Optical Link. Connect the optical
fibre connector marked
T
on one module to
R
on the other module, and vice-versa.
Note:
It is not possible to establish a link by connecting a 100Mb/s Ethernet Optical Transceiver to a
10/100/1000Mb/s auto switching Ethernet Optical Transceiver as the fibre interfaces are incompatible.
To establish a successful working link, two modules with the same speed specifications must be used.

Front Panel Indicators
The Transceiver has a number of front panel LEDs for indication of essential status information of the
module. The following table shows the operation of the front panel LEDs :
