Electricity: Communication Wiring

Home | DIY Guides | Prev: Home-automation Systems | Next: Older Phone Systems

Introduction

The older phone wiring and coaxial cables in our homes are rapidly becoming outdated for supplying digital televisions and Internet connections with high- speed, high-performance connectivity.

Home-network-distribution systems can be installed in both new construction and during remodeling projects to help consolidate, simplify and organize all your audio, video, telephone and other systems in one convenient location. These needs can generally be handled by installing only two types of cable—Category 5e UTP (unshielded twisted pair) cable for voice arid data, and RG-6 shielded coaxial cable for television or video. As your needs change, a central distribution system allows you to easily reconfigure, enhance or expand a system. Similarly, compatible devices can be connected in the distribution box by using “jumper” cables. The distribution system essentially connects all information out lets in each room directly to a central hub.

Buy high-quality cable and be sure to select a distribution box that will accommodate your expansion needs.

1. Install distribution box. Drill 2-1/2-in. holes in wood framing and install 2-in. PVC conduit sleeves for routing cables to attic and basement.

2. Install low-voltage open-back remodeling boxes at desired locations. Check for hidden obstructions inside walls before cutting holes for boxes.

3. Fish cables from distribution box to outlet locations. Clearly identify or label cables on both ends. Leave extra cable length at all boxes.

4. Install a ground wire from the distribution box to the main electrical service location in accordance with local code and manufacturers instructions.

5. Neatly install cables and wires using appropriate connectors or terminals. To ensure good system performance, avoid sharp bends in cables. (Coaxial splitter, Voice and data module)

Connecting CAT-5e Cable

To connect Category 5e cable, cut into the end of the cable with an electrician’s scissors (don’t use a knife). Pluck out the internal string and “zip” open a few inches (centimeters) of cable jacket. Carefully remove the jacket. Gently untwist the colored wire pairs and bend them into the terminals on the jack. Use a punch-down tool to terminate the wires. Snip off excess wire length. (Connector cover, CAT-5e modular jack)

Connecting Coaxial Cable

To connect coaxial cable, adjust the stripper, then spin it around the cable with 5/8 in. (16 mm) of cable projecting past the tool. Use your fingernails to expose the inner signal wire, white insulation arid metal shielding. Push on the F-connector and crimp with the tool. Leave 1/8 in. (3 mm) of wire past the end of the connector. Screw F-connectors to F-jacks and snap into cover plate. (Coaxial Crimp-on F-jack F-connector).
