2 Channel Video Transmit Unit with Bi-directional Data
The AMG4723-CWDMn-MP is a standalone two channel video transmit unit designed to transmit 2
video signals and transmit and receive 1 data signal over two singlemode fibres.
The AMG4723-CWDMn-MP transmits on a CWDM wavelength defined by the 'n' in the CWDMn
partno. as detailed in the table overleaf, but can receive from any 1310nm or 1550nm band
wavelength.
The AMG4723-CWDMn-MP is designed to be powered using an AMG2003 standalone power supply.
The AMG4723-CWDMn-MP is designed to operate with AMG4724-CWDMn-MP or rackmount
equivalent AMG4724-CWDMn-R two channel video receive unit in a point to point configuration.
