Introduction
Unit Functional Schematic
The
AMG4707A
-
DR
-
SF
transmits
and receives optical signals from
both a primary and a secondary
optical channel.
The two optical channels are
transmitted on the same optical
fibre i
n opposite directions,
operating at different
wavelengths. The primary
channel operates on 1550nm and
the secondary channel on
1310nm.
The
AMG4707A
-
DR
-
SF
receives
data signals and drops off data
signals transmitted from an
AMG4708A
-
DR
-
SF
receiver. It
then
inserts data signals onto the
outgoing optical signal.
Optical Connection
The
AMG4707A
-
DR
-
SF
is connected as illustrated below when used with an
AMG4708AG
-

Data and Audio Channel Configuration
The data expansion board slots are accessed by removing the AMG unit
from its case. A data channel
is active when a daughter board is installed in the required data channel slot. Each data interface
board enables one bi
-
directional channel.
Daughter Board Layout
The channel slots are as follows:
Data and Audio Daug
hter Board Fitting Instruction
The data and audio daughter boards pushed on to the pin headers mounted on the data expansion
boards. Ensure that the connectors are lined up correctly and not offset before pushing firmly in place.
Note that the data and aud
io channel numbers are associated with each slot. This allocates the pin
numbers on the rear panel connector together with the front panel LED indicators.

Mounting Details
The AMG unit is supplied with a clip
-
on mounting bracket which should be attached to a panel or wall
using 2 off 4.0mm screws, see diagram on page 1 for dimensions. The unit is clipped into the
mounting bracket, and is
then held firmly in position.
Removal / replacement from / to the Case
Note:
-
The AMG unit PCB's are static sensitive. Handle with proper care and use normal electrostatic
discharge (ESD) procedures. Use properly grounded protection (for example, wrist
straps) when
handling the PCB.
To remove units from the case to access the data expansion boards and the daughter boards, remove
the 2 or 4 fixing screws on the rear panel and slide the PCB's out of the case.
Ensure that the fibres do not snag or get t
rapped.
To replace the PCB's into the case, slide the PCB's gently into the case aligning the boards with the
appropriate slots. Ensure that the fibre do not snag or get trapped.
Safety
AMG Optical Fibre Products use Class 1 laser systems in accordanc
e 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 optical fibre systems, please see
EN 60825
-
2:2000 or your local safety officer.
Maintenance and Repair
There are n
o user serviceable parts within AMG products. See unit data sheet for full specification.
In case of problem or failure, please call your local support centre or contact:
