18221-A ADCP-75-169 • Issue 1 • June 2004 18824-A Figure 4. Expansion Panel 3.2 Wavelength Division Multiplexer System The Wavelength Division Multiplexer (WDM) system is an accessory product that is used when it is desirable or necessary to combine the forward and reverse path optical signals from one Digivance system onto a single optical fiber. Each WDM system consists of a host module and a remote module. The HU provides a mounting slot for installing a WDM host module. Both the RU outdoor cabinet the RU indoor mounting shelf provide a mounting slot for installing a WDM remote module. Each WDM module consists of a bi-directional wavelength division multiplexer mounted within a power-paint coated sheet metal enclosure. A straight SC-type optical connector port is provided for connecting the forward/reverse path optical fiber to the WDM module. A pair of pigtail leads with SC-type connectors are provided for connecting the WDM module to the forward and reverse path optical ports on the HU or STM. The WDM host/remote module is shown in Figure 5. 17013-A Figure 5. WDM Host/Remote Module Page 6 © 2004, ADC Telecommunications, Inc. ADCP-75-169 • Issue 1 • June 2004 Page 7 © 2004, ADC Telecommunications, Inc. 3.3 Coarse Wavelength Division Multiplexer System The Coarse Wavelength Division Multiplexer (CWDM) system is an accessory product that is used when it is desirable or necessary to combine the forward and reserve path optical signals from up to four Digivance systems onto a single optical fiber. Each CWDM system consists of a Host Module, Host Module mounting shelf, and Remote Module. The CWDM Host Module mounting shelf can support up to three CWDM Host Modules. The RU single-STM mounting shelf and the outdoor cabinets provide a mounting slot for installing a CWDM Remote Module. The CWDM Host Module and Host Module Mounting Shelf are shown in Figure 6. The CWDM Remote Module is shown in Figure 7. For complete information about the CWDM system, refer to the Digivance System Coarse Wavelength Division Multiplexer User Manual (ADCP-75-142). Figure 6.

The installation procedures for the Interface Panels are provided in the Digivance Long Range Coverage Solution SMR Interface Panels User Manual (ADCP-75-143). The installation procedures for the CWDM Host Module and the Host Module Mounting Shelf are provided in the Digivance System Coarse Wavelength Division Multiplexer User Manual (ADCP-75-142). Installation of the RU components may proceed separately from installation of the HU. 4.1 Before Starting Installation Before beginning the installation, review the system design plan with the system engineer. Make sure each equipment installation site is identified and located and all cable runs are mapped out. Also identify all tools and materials that are required to complete the installation. 4.1.1 Tools and Materials The following tools are required to complete the procedures in this section: • Box cutter • Pencil or scribe • Medium size flat-bladed screwdriver • Phillips screwdriver (#2) • TORX screwdriver (T20 bit) • Pliers • Wire cutters • Wire stripper • Tool kit for attaching N-type male connectors to coaxial cable • Multimeter • Optical power meter The following materials are required to complete the procedures in this section: • #18 AWG (1.0 mm) insulated stranded copper wire (for chassis grounding wire) • #18 AWG (1.0 mm) red and black insulated copper wire (for DC power wires) • Category 3 or 5 cable (for external alarm system wires) • #6 ring terminal (1) for #18 wire (for chassis ground wire connection) • #6 fork terminals (2) for #18 wire (for DC power wiring connection) • Single-mode patch cord(s) with SC connectors (1, 2 or 3 depending on the application) • High performance, flexible, low-loss 50-ohm coaxial cable • N-type male connectors • Wire ties Page 8 © 2004, ADC Telecommunications, Inc. ADCP-75-169 • Issue 1 • June 2004 4.2 Unpacking and Inspection This section provides instructions for opening the shipping boxes, verifying that all parts have been received, and verifying that no shipping damage has occurred. Use the following procedure to unpack and inspect the HU and any accessories: 1. Open the shipping cartons and carefully unpack each component from the protective packing material. 2. Check each component for broken or missing parts. If there are damages, contact ADC (see section 6 at the end of this manual) for an RMA (Return Material Authorization) and to reorder if replacement is required. 4.3 OSP Fiber Cable Installation Guidelines The outside plant (OSP) fiber optic cables should be routed between the HU and RU and terminated before the equipment is installed. A diagram of a typical OSP cable routing is shown in Figure 8. At the HU...
