The AMG4782R-1550-C is a standalone eight channel video receive unit designed to receive eight
video signals from an AMG4781-1550-C, or AMG4781R-1550-CR, 8 channel video transmitters. The
units require one single mode optical fibre for the transmission of the video. It incorporates a
1550nm/1310nm wavelength division multiplexer. This allows the user to combine a signal from a unit
transmitting at 1310nm wavelength onto the same fibre. The 1310nm signal can be in the same or in a
different direction to the 1550nm signal.
The AMG4781R-1550-C is designed to plug into an AMG2000 or an AMG2005 Subrack which in turn
fits into a 19” rack system.

Mounting Details
The unit is designed to be mounted within an AMG2005 Subrack on standard card guides. Note the
AMG2005 Subrack is supplied with guide rails every 14HP. In order to fit this unit in the Subrack it
may be necessary to move some card guides by pulling gently on the card guides.
Safety
The 4700 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 AMG4700 products.
