Fiber CAP L2 Overview F IBER CAP L2 O VERVIEW This installation guide describes the Fiber CAP L2, which interfaces with a Classic CAN or TEN via an optical link. This allows the Fiber CAP L2 to provide data over Single-Mode Fiber (SMF) or Multi-Mode Fiber (MMF). Power for Fiber CAP L2s is provided over External AC/DC or remotely through hybrid fiber. On the downlink, the Fiber CAP L2 converts data arriving at the CAP L2 to analog signals and sends them to the Antenna ports.

Mount the Fiber CAP L2 Mounting CAP L2 with a Wall Mounting Kit The following sections provide the installation methodology and steps required to mount a CAP L2 to a wall. When wall mounting a CAP L2, the recommendations should be observed. Table 12.
Mount the Fiber CAP L2 4 Use the wall bracket as a template to mark the holes at the location where you will mount the UAP 2. 5 Secure the wall mount bracket to the wall, using four anchor screws. The anchor screws do not ship with the CAP L2 as the anchor type is dependent on the on-site conditions (wall structure and materials). Use screw anchors that are rated for the mounting surface. The hole for the screws in the bracket is 7.5 mm in diameter and will accommodate screws between 5.8 mm and 7.5 mm.
Mount the Fiber CAP L2 7 Lift the CAP L2 onto the bracket and align the holes on the CAP L2 with the rear holes of the bracket, closest to the mounting surface. Ensure that the hanger tab is secure on the bracket. 8 Tighten the CAP L2 M5 screws, provided with the CAP L2, on both sides on the top and bottom at a Torq of 6.5 Nm. M5 screws 9 Confirm that the CAP L2 is securely attached to the Wall Mount Bracket. M0203A9B_uc © September 2022 CommScope, Inc.
Mount the Fiber CAP L2 10 After you mount the CAP L2 on a wall, follow the steps in • • "Ground the Fiber CAP L2 (Optional)” on page 36 (if grounding is required) "Connect the Fiber CAP L2 to a Passive RF Antenna” on page 37 Mounting a CAP L2 with an AC/DC Power Supply Kit An AC/DC Power Supply Kit provides a 48V External Power Supply that converts local AC power to DC power for the CAP L2.
Mount the Fiber CAP L2 5 Follow the steps in "Unpack and Inspect the CAP L2 and Optional Accessories” on page 18. Wiring the AC/DC Power Supply Kit The CommScope Local AC Power Supply Kits are available in three configurations as shown in "CommScope Local AC/DC Power Supply Kits” on page 25.

You then need to follow one of the following procedures that meets the powering requirements of this installation.
Mount the Fiber CAP L2 4 Strip the insulation of the composite cable for 100 cm and the fibers for 90 cm, and then shorten the copper cables to 25 cm. 5 Insert the composite cable in the first cable gland and separate the multi-fibers cable from the copper wires. It is necessary to remove the nut to perform this action. The cable must be fed through the nut and it must be retightened once finished. 6 Bend the spliced fibers using the corner guides and fix the splices to the splice holder.
Mount the Fiber CAP L2 9 Remove the sealing nut and rubber of the cable gland and insert the optical cables. 10 Place each cable into one of the grooves of the seal insert. 11 Press the seal insert into the clamp ring opening. 12 Fix the optical cables inside the box using one cable tie and tight the sealing nut. 13 It is possible to separate the optical cables and use two different cable glands. Remove the sealing nut and rubber on each cable gland.
Mount the Fiber CAP L2 15 Insert the copper wires in the first multiple terminal connectors. See markings on the internal support. Then fasten the copper cables inside the box using one cable tie. 16 Remove the sealing nut and insert the CAP L2 supply cable and tighten the sealing nut. 17 Connect the supply cable to the terminal strip and fix it inside the box using one cable tie. It is possible to connect a second supply cable to cascade two CAP L2s, as shown in the graphic to the right.
Mount the Fiber CAP L2 Wire a Hybrid Fiber Splice Box for 4-Wire Power with Limited Power Source Use the 4-wire power setup when Limited Power Source (LPS) is required by local electrical/safety codes. Each CAP L2 can accept two Limited Power Sources from the DC PSU where local regulations require it. In the following wiring procedure, you will connect the power wires from the Hybrid Fiber Splice Box to a DC Power Supply Unit (PSU).
Mount the Fiber CAP L2 2 After you have wired the Hybrid Fiber Splice box, complete the steps in "Wall Mount a CAP L2 Using a CAP L2 Hybrid Fiber Splice Box Kit (optional)” on page 35. Wire a Hybrid Fiber Splice Box for 2-Wire Power without Limited Power Source Each CAP L2 can be powered by 2 wires if LPS from the DC PSU are not required by local regulations.. All four pins of the proprietary CAP L2 4-pin 36 to 60 Vdc Power connector must be terminated.
Mount the Fiber CAP L2 2 After you have wired the Hybrid Fiber Splice box, complete the steps in "Wall Mount a CAP L2 Using a CAP L2 Hybrid Fiber Splice Box Kit (optional)” on page 35. Wall Mount a CAP L2 Using a CAP L2 Hybrid Fiber Splice Box Kit (optional) The steps in this section pertain only to those installations that require the use of the optional Hybrid Fiber Splice Box to provide fiber and power to the CAP L2. 1 2 3 4 5 6 Remove the Hybrid Fiber Box cover.
