2644R
AMG2644R is a rackmount four channel video receive unit. It also provides a single RS485/RS422 or
RS232 bi-directional data channel. The AMG2644R is designed to plug into an AMG2000 or an
AMG2005 subrack which in turn fits into a 19" rack system.
The AMG2644R is designed to operate, with either an AMG2643R or AMG2643 4 channel video and
bi-directional data rackmount or standalone transmit unit respectively, over two Singlemode optical
fibres in a point to point system.

Connections

Video Output Connections

Connector ........................................... 75 ohm BNC Socket.
Output Impedance ............................... 75 ohm terminated.
Output Level ........................................1 volt p-p nominal
Frequency Response .......................... 10Hz to 5.75MHz min.
No of output channels.......................... 4

Optical Connections

OPTO OUT
Connector ............................................FC/PC
Optical Launch Power ......................... -5dBm
Wavelength .......................................... 1310nm
OPTO IN
Connector ............................................FC/PC
Optical Sensitivity ................................ -22dBm
Wavelength .......................................... 1310nm
Note: - The transmission distance on multimode fibre will tend to be limited by the bandwidth of the
fibre rather than the optical dynamic range. It is recommended that 50/125 optical fibre is used as this
will have a higher bandwidth than 62.5/125 fibre. The AMG2643R and AMG2644R will transmit and
receive over a minimum of 1km of 50/125 fibre and will typically transmit and receive over 2km of
50/125.

Power Connection

Power supply ....................................... from plug in connection on the 2000 or 2005 subrack
Power consumption .............................10 Watts max.
