Cable Types Cable Types Two basic types of cable are used in multimedia installations. Coaxial cable for video based applications such as satellite or cable television, and twisted pair cable for data communication based applications like computer networking and telephone installations. Coax Cable RG-6 Quad provides the best protection from outside interference that can degrade the signal while traveling through the cable. It is double shielded with two layers each of foil and braiding.
Coaxial Connector Selection Guide Compression Pro Connection Push-On Best Connection Crimp-On Better Connection Twist-On Good Connection Pro—Compression Connector Professionals use compression connectors because they are approved, and in most cases—required, by cable and satellite providers. With the proper stripping and terminating tools, anyone can install compression connectors. The major advantage in using compression connectors is that they provide for permanent watertight connection.
Definition of Terms Definition of Terms Braid Same as shielding—Typically made from a number of smaller aluminum or copper conductors interwoven together to form an outer conductor around the dielectric core. The braiding stops lower frequency noise from interfering with the signal traveling down the center conductor. Center Conductor The solid center wire, made of steel or copper, within the cable that carries the signal.
Coaxial Installation Steps Step 1 – Cut Cut Cable Cut cable using a round cutter to maintain cable geometry. Data T-Cutter CAT. NO. 45-074 Step 2 – Strip Strip Cable All F-connectors and BNC compression connectors require a two-step ¼9, ¼9 strip. Crimp BNC connectors require a 3 step strip. (See product packaging for instructions.) Jacket ⁄49 Max 1 Dielectric wrapped in braiding ⁄49 1 Center conductor Coax Stripper CAT. NO.
Coaxial Installation Steps Step 3 – Terminate Compression F-Style Press the connector onto the cable until the white dielectric is even with the center hole of the connector. Place the prepared connector completely into the tool’s compression chamber. When the connector is in place, squeeze the tool handles together until the connector is fully compressed. CAT NO. 30-603 Finished connector Crimp F-Style Insert stripped cable into connector until the white dielectric is even with the center hole.
Data Wiring Cable Pulling Tips Maximum pulling tension—25 lbs. Minimum bending radius—4 times diameter of cable 12 inches from power lines 4 feet from motors or transformers 12 inches from fluorescent lighting Should cross perpendicular to power lines Cable untwisting allowed after termination: n 3 inches for Category 3 cable n 0.5 inches for Category 5e and Category 6 cable Avoid kinking or bending cable. Cable ties should not be overly tight.
Terminating Data Modular Plugs Step 1 – Cutting Aciduis num do odolendigna CAT. NO. 30-496 Step 2 – Strip Strip off 2 inches of the outer jacket. CAT. NO. 45-165 Step 3 – Wiring Configurations Separate the twisted pairs into the proper sequence either EIA/TIA 568 A or B. T568A T568B (NOTE: Wiring configurations reflect flat surface of the modular plugs facing up, with tab side down. Flatten all pairs together Flatten the pairs so they are close together and in the right color sequence.

Data Jack What is a Data jack? A Data jack is typically a wall or patch panel outlet that provides a place to plug in a patch cable and connect to a network from a room or an office. Data jacks for Cat 5e and Cat 6 applications are very common today and are becoming a standard feature of many new homes. An installer will terminate the cable to the jack using a punchdown tool as shown. Refer to the jack manufacturer for instructions on how to properly install and terminate the cable to the jack.
Terminating a Data Jack Step 1 – Cutting Aciduis num do odolendigna CAT. NO. 30-496 Step 2 – Strip Strip off 2 inches of outer jacketing of cable. Avoid damaging or nicking of the pairs. Bend cable, remove jacket Score cable with stripper CAT. NO. 45-165 Step 3 – Wiring Configuration Determine the wiring configuration to use. Separate the pairs and insert them into the colored slots. The jack will have both wiring codes printed on it. No more than 1⁄2 inch of each pair should be left untwisted.
Testing a Data Jack Step 5 – Testing Testing the connections Once you have everything terminated it is advised to test the cabling using a wiremap tester. Check for opens, shorts, split pairs, reversals, and miswires. Tester Choices VDV MultiMedia Tester CAT. NO. 33-856 LinkMaster CAT. NO. 62-200 LinkMaster Pro XL CAT. NO. 33-880 See page 9 for wire error definitions.
Terminating Telephone Modular Plugs What is an RJ-11 Modular Plug? Telephones use patch cords to connect to the wall outlet.. The cables are terminated with an RJ-11 Modular Plug. RJ-11 is a 2 pair or 4 wire connector which supports up to 2 phone lines. All phone cords are wired where the two ends of the cable are wired exactly opposite of each other. CAT 3 CAT 5e CAT. NO.
Terminating Telephone Modular Plugs Step 1 – Cut, Strip Trim end of cable and strip off 1⁄4 inch of outer jacket of cable with tool as shown. CAT. NO. 30-496 Strip outer jacket and trim cable to 1⁄49 Step 2 – Terminate Insert stripped wires into RJ-11 plug (follow below color codes). Maintain the order of the wires while inserting into plug. Insert connector into RJ-11 die nest in middle of tool. Squeeze handles firmly to crimp the connector.
Splicing Connections IDC Connections – “Jelly Beans” These connectors are used to splice or tap telephone wires together. They are moisture resistant to prevent corrosion. They are designed for use on solid copper conductors. Insert wires and squeeze with IDC tool. CAT. NO. 45-719 3 Wire Butt Splice Splices or taps up to three wires 19-26 AWG. Used to splice telephone wires together to run an extension to another phone. CAT. NO. 85-925 2 Wire Tap Splice CAT. NO. 85-900 Taps a telephone wire 22-26 AWG.
