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

– 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
