ADC’s Value-Added Module (VAM) System provides the flexibility and functionality to easily
incorporate optical components into the network. Optical components, such as wavelength division
multiplexers (WDMs) and tap monitors, add capacity and increase reliability with minimal installation
cost and time. Wavelength division multiplexers enable the service providers to double the capacity
of the existing network without installing new fiber; tap monitors provide easy access to the network
for testing and monitoring without interruption of service....
