Introduction
Unit Functional Schematic
The
AMG3608BERN-DR-SF
transmits and receives optical
signals from both a primary and a
secondary optical channel.
The two optical channels are
transmitted on the same optical fibre
in opposite directions, operating at
different wavelengths. The primary
channel operates on 1550nm and
the secondary channel on 1310nm.
The
AMG3608BERN-DR-SF
receives and drops off data, contact closure & Ethernet signals
transmitted from up to eight
AMG3603B5E-DR-SF
transmit units. It then inserts data, contact closure
& Ethernet signals onto the outgoing optical signal
As each unit regenerates the optical signal, the optical dynamic range between each optically
connected node is 17dB.
Data Channel Configuration
At the
AMG3603B5E-DR-SF
or rackmount
AMG3603B5ER-DR-SF
insert unit, "B" channel data can
be inserted on one to eight "B" data channels transmitted on the optical fibre. The "B" data channel
number of each insert unit is set by the rotary switch on the front panel of the unit.
It is normal to set each insert unit to a different channel number. If the same number is used twice, an
insert unit connected 'down stream' on the primary optical route will 'over-write' any coincident data
channel coming from the previous insert unit and those data signals will be lost.
The switch channel numbers 1 to 8, correspond to data channels 1-8. Unused switch channel
numbers 0 & 9 duplicate data channel selections 1 & 8 respectively. i.e. setting switch to position 0 or
1 selects data channel 1 and setting switch to position 8 or 9 selects channel 8.
