AMG2648R Instruction
Sheet D15534-01
Optical Connections
OPTO OUT
Connector ............................................FC/PC
Optical Launch Power ......................... -5dBm
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
AMG2647
and
AMG2648R
will transmit and
receive over a minimum of 1km of 62.5/125 fibre and will typically transmit and receive over 2km of
50/125. The transmission distance will typically be longer than this but will depend of the performance
of the optical fibre.
OPTO IN
Connector ............................................FC/PC
Optical Sensitivity ................................ -22dBm
Wavelength.......................................... 1310nm
Power Connection
Power supply ....................................... from plug in connection on the 2000 or 2005 subrack
Power consumption ............................. 12 Watts max.
Indicators
Power................................................... Green
– unit powered
Off
– no power applied to unit
Opto Sync RX ...................................... Green
– optical channel receiving
Off
– optical channel not receiving
Opto Sync TX ...................................... Green
– optical channel transmitting
Off
– optical channel not transmitting
Video Present ...................................... Green
– video signal present on video the channel
indicated.
Red/Green – video channel available on the fibre but no
video signal being transmitted
Off
– no video channel available on the fibre.
(when data slot contains a data daughter board)
Data Present TX .................................. Green
– logic one present on the data input
Red
– logic zero present on the data input
Off
– tri-state off or no connection on the data input
This represents the data signals being transmitted on the optical fibre
Data Present RX .................................. Green
– logic one present on the corresponding data
output
Red
– logic zero present on the data output
Off
– tri-state off on the data output
This represents the data signals being received on the optical fibre
(when audio slot contains an audio daughter board)
Audio Present TX ................................ Green
– when an audio level between –40dBm and
+0dBm is on the audio input (600ohm).
..................................................... Red
– when an audio level above 0dBm is on the
audio input. (600ohm).
..................................................... Red/Green – when an audio level peaking above 0dBm is on
the audio input. (Note audio daughter board will
accept up to +6dBm (600ohm)).
..................................................... Off
– when an audio level is below –40dBm on the
audio input. (600ohm).
This represents the audio signals being transmitted on the optical fibre
