8 Channel Video Receive Unit with 1 Bi-directional Data
Channel and integral WDM coupler for a Singlemode Fibre
The AMG4784R-SF-CWDMn-C is a rackmount eight channel video receive unit designed to receive 8
video signals and transmit and receive 1 data signal over one Singlemode fibre. The AMG4784R-SF-
CWDMn-C transmits on a CWDM wavelength defined by the 'n' in the CWDMn partno. as detailed in
the following table, but can receive from any 1310nm or 1550nm band wavelength. It incorporates a
CWDM "drop and insert" optical multiplexer. This allows the user to combine a signal from a unit
transmitting at an alternative CWDM wavelength onto the same optical fibre.
The AMG4784R-SF-CWDMn-C is designed to plug into an AMG2009 or AMG2015 subrack, which in
turn fits into a 19" rack system.
The AMG4784R-SF-CWDMn-C is designed to operate with AMG4783-SF-CWDMn-C or rackmount
equivalent AMG4783R-SF-CWDMn-C eight channel video transmit unit in a point to point
configuration.
