Connections
Video Output Connections
No. of channels....................................4
Connectors ..........................................75 ohm BNC Socket.
Output Impedance ...............................75 ohm terminated.
Output Level ........................................1 Volt p-p nominal
Frequency Response...........................10Hz to 7MHz.
Optical Connections
PRIMARY OPTO OUT
Connector ............................................LC/PC
Primary Optical Launch Power ............-5dBm
Wavelength..........................................1310nm
Optical Fibre ........................................Multimode 50/125 or 62.5/125**
PRIMARY OPTO IN
Connector ............................................LC/PC
Primary Optical Sensitivity...................-22dBm
Wavelength..........................................1310nm
Optical Fibre ........................................Multimode 50/125 or 62.5/125**
**Note: the transmission distance is limited by the bandwidth of the Multimode optical fibre. The optical
data rate is 1.25Gbits/s. The maximum bandwidth specification at this data rate for Multimode fibre is
2km. although in most cases the units will operate successfully over longer fibre lengths. It is
advisable however for distances greater than 2km, to have the optical fibre tested.

Supply Voltage.....................................13.5 to 18.0 Volts DC.
Maximum Power .................................10 Watts
Ethernet Connection
Ethernet Data Connector ....................RJ45
Interface...............................................Auto-negotiation up to 100BASE-TX full duplex
Ethernet Data Rate ..............................Maximum 100Mb/s total Ethernet traffic on fibre
Ethernet Operation
In order for the AMG system to transmit Ethernet signals, an onboard RJ45 Ethernet interface or
X16003 Ethernet interface adaptor should be fitted to both the Transmit unit and the Receive unit.
The Ethernet interface can operate at either 10Mbits/s half duplex, or 100Mbit/s full duplex, and data is
transmitted from one port the other port with the minimum of delay or buffering.
The 100BaseT port does not implement MDI/MDIX; it should be connected with a straight though
cable to an external switch port and with a cross over cable when connected directly to a PC or DTE.
