NG3 12-Position Value Added Module Panel

The NG3 12-Position Value Added Module (VAM) Panel is a rack-mount panel designed for
mounting on the NG3 rack. The panel has a hinged drawer that swings out to provide access to
the VAM's within. The VAM panel, shown in
Division Multiplexing (WDM) functionality to be incorporated into specified optical circuits at
the NG3 frame. Optical splitters are used to divide the optical signal for distribution to multiple
ports in order to provide test, access, and monitoring capability. WDM's are used to increase
transmission capacity, combine separate services on an existing network, and to provide non-
intrusive testing.
The following basic VAM types are available:
• Splitter–Distributes the optical signal to multiple circuits
• Monitor–Provides a test or access point in an optical circuit
• Wavelength Division Multiplexer–Allows transmission of two optical wavelengths in the
same direction on the same fiber (unidirectional) or transmission of two optical
wavelengths in the opposite direction on the same fiber (bidirectional)
The VAM panel provides twelve micro VAM assembly mounting positions. The VAM
assemblies must be ordered separately and installed in the panel on an as needed basis. Each
VAM assembly, shown in
adapter ports. The same adapter types offered with the termination panel and termination/splice
panel are also available with the VAM assembly.
