Instruction Manual
Eight Channel Video TX Unit with integral WDM coupler for
addition of 1310nm signals also providing a dual path output
for a dual redundant point to point system
AMG2781R-1550-DR-WDM is an eight channel video only transmit unit designed to transmit eight
video signals down two separate Singlemode fibres for dual routed redundant systems. It also
includes a 1310/1550nm optical coupler so that either an additional 4 or 8 video channels can be
transmitted down both fibre optic paths operating at 1310nm. These further 4 or 8 channels require the
use of an AMG2781R or AMG2741R unit. See below for connection and operation. The AMG2781R-
1550-DR-WDM is designed to plug into an AMG2000 or an AMG2005 Subrack which in turn fits into a
19” rack system.
The AMG2781R-1550-DR-WDM is designed to operate with AMG2782R-1550-DR-WDM eight
channel video only receive unit which combined with either a AMG2782R-DR or AMG2742R can
receive a total of either 12 or 16 video channels respectively via two routes. The system will operate in
a way such that if either route should fail there will be no loss of video channels.

Introduction
Unit Functional Schematic
The unit combines the signals from eight video inputs and
transmits them in a digital format optically at a wavelength
of 1550nm. This optical signal is combined within the unit
with an optical signal operating at 1310nm which can be
inserted from another AMG2700 unit, allowing for either 12
or 16 video signals to be transmitted on the output fibre.
The 1310nm and 1550nm signals although on the same
optical fibre do not interfere with each other and can be
separated at the receiver. The combined 1310nm and
1550nm signal is then split equally and transmitted out of
the unit on two optical fibres with the same signal
transmitted along each fibre. One route is regarded as the
primary route and one the secondary route. It is optional to
connect the up stream 1310nm signal in so much as the
unit will operate independently transmitting only the 1550nm signal.
Optical System Connection
The units are designed to be connected a point to point system as shown below.
The schematic above shows 16 channel operations. For 12 channel operation a 2741R should be
used instead of the 2781R and a 2742R-DR should be used instead of a 2782R-DR.
For 8 channel operation the 2781R and 2782R-DR need not be used. However the same functionality
can be done using the 2781R-DR and the 2782R-DR as these units do not include the WDM couplers
and operate at 1310nm.
Dual Redundant Operation
The optical signal is transmitted simultaneously along both the primary optical route and the
secondary optical route. In the event of a break in either the primary optical route or the secondary
optical route the transmission of the 16 video channels will not be affected and no video signals will be
lost at the receiver. See below.

Safety
The 2700 series of products uses a Class 1 laser system in accordance with EN 60825-2:2000.
It is always advisable to follow good practice when working with optical fibre systems. This includes:
Do not stare with unprotected eyes or with any unapproved collimating device at fibre ends or
connector faces, or point them at other people.
Use only approved filtered or attenuating viewing aids
For other safety issues and advice on good practice associated with the optical fibres systems see EN
60825-2:2000 or your local safety officer.
Maintenance and Repair
There are no user serviceable parts within the AMG2700 products.
In case of problem or failure contact your local support centre or AMG Systems Ltd, Technical Support
