AMG2684 Instruction
Sheet D15700-00
Introduction
Unit Functional Schematic
The
AMG2684
receives a 1310nm optical signal and
drops of video and data transmitted from an
AMG2683
transmitter. It transmits the data signals onto the
outgoing 1310nm optical signal. The video signals are
received from the 8 channels available on the optical
fibre.
Optical System Connection
The
AMG2684
is connected as illustrated below when used with an
AMG2683
8 channel transmitter.
Note that where necessary repeaters can be added at nodes to increase the average distance
between nodes.
