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. While the most common usage of the VAM is in the central office, these same components can be used successfully in the outside plant environment. For example, remote locations with minimal fiber capacity can be connected through an OSP VAM application, eliminating the need to dig and install new fiber. Below is a sketch of (two) remote locations connected to a central office using ADC’s FSS96 below ground cross-connect enclosure. Optical Components Increase Network Capacity and Provide Faster Service Delivery application note Central Office VAM, in an FDF, NGF or OMX ™ Frame The VAM protects the WDM devices required to mux/demux the signals to/from the remote locations Outside Plant WDM in an FSS96 Cross-Connect Enclosure muxes the signals for transport on a single fiber to the CO and demuxes the signals to be routed to the correct location Remote location 1310 nm Signal Remote location 1550 nm Signal 1310/1550 combined on existing fiber Outside Plant Below Ground or Above Ground Cross-Connect Cabinet Examples: ACE-200, ACE-400 or BGX cabinets 90%-98% of the signal passed to CO, subscriber, or handoff 2%-10% of the signal available for non-intrusive testing Signal from CO or handoff The VAM housing protects the component from mechanical damage; however, the component itself is well-suited for the outside plant environment. Splitters and WDM components require no electronics and they are rated for severe environments from -40°C to +85°C with a relative humidity less than 80%. Tap monitors have the same environmental rating; however they are suited for environments where network support personnel need easy, non-intrusive access to the network. Tap monitors increase the ability to monitor and test the network at the edge of the network or in remote locations. The sketch below shows a tap monitor application in an outside plant environment. 2 www.adc.com • +1-952-938-8080 • 1-800-366-3891 7/02 • 1235693 Optical Components In OSP Value-Added Modules in the Outside Plant Environment FSS Cross-Connect Enclosure VAMs can be deployed in all ADC outside plant enclosures. In the FSS cross-connect enclosure, the VAM is installed where the splice trays would normally be mounted. They can be added incrementally in the field as additional service is required. The FSS cross-connect enclosure houses a combination of splice trays and VAMs and should be ordered as a fully configured system that includes pigtails, splice trays, VAMs and cable termination/blocking kits per customer specification. Please contact ADC technical support to configure the FSS cross-connect enclosure when optical components are added to increase the functionality of the enclosure. 1 2 4 6 Figure 1 FSS-WH2U2UAA1A Shown with (6) VAMs. Note that #2 VAM is shown without pigtails. Pigtails are numbered on connector boots for easy identification when optical components are housed inside.

The VAM is available in a “single-high” or “dual-high” housing. A single-high VAM has (6) front ports for easy access to the optical components inside. A single-high VAM will house (2) WDM devices, (2) tap monitors or (1) 1x4 splitter. A dual-high VAM provides up to (18) ports for a combination of optical components or a 1x32 splitter. Both the single-high and dual-high VAM feature the removable retainer for easy access to the internal connectors. The outside plant cabinets are designed to house either of the following chassis: • 4" high x 19" wide chassis, Catalog # OSP-MINSPI. (See Figure 2) • 7" high x 19" wide chassis, Catalog # OSP-STDSPI. (See Figure 3 for ACE-200 example) Figure 3 OSP-STDSPI Chassis Shown in an ACE-200 Above Ground Cross-Connect Enclosure shown with the door open Figure 2 OSP-MINSPI Chassis Capacity: (6) – Single-high VAMs (2) – Dual-high VAMs 30" (76.2 cm) 51" (129.54 cm) 19.0" (48.26 cm) 4.0" (10.16 cm) ADC Telecommunications, Inc., P.O.
