AMG3782ERN 

Instruction Manual  

8 Channel Video Receive Unit with Ethernet for a 

Singlemode Fibre Ring - includes AMG NMS Network 

Management Interface 

 

 

 

 
 

 

 
The 

AMG3782ERN

 is a rackmount eight channel video receive unit designed to receive 8 video 

signals from a singlemode optical fibre ring. It also provides full duplex 100BaseT Ethernet 
connectivity around the ring.  
 
The 

AMG3782ERN

 is designed to plug into an 

AMG2005

 or 

AMG2009

 subrack, which in turn fits into 

a 19" rack system. It also includes an AMG Management Interface to allow management of the system 
using the AMG SNMP enabled Management software. 
 
The 

AMG3782ERN

 is designed to operate with 

AMG3741E

 or rackmount equivalent 

AMG3741ER

 

four channel video and data insert units. It may also be used with other combinations of single, dual 
and four channel video, data and Ethernet insert units. 
 
An 

AMG3782ERN 

receive unit will 'drop off' up to eight video channels which are being transmitted 

around the fibre ring from up to eight single channel insert units, or from an equivalent combination of 
multi-channel insert units.
