2 Brain storm Whats structured cabling? Whats the meaning of structured? Whats the meaning of standardisation? Is my house cabled? Where, when and how was cabled? Why the law covers the structured cabling problem?

3 Objectives 1. Structured cabling systems 2. Terminology 3. Passive Devices 4. Cross Connect technology I. Documentation II. Installation technique III. Mini-glossary for the final exam

4 Structured Cabling Systems Structured cabling is a method for creating an organized cabling system that can be easily understood by installers, network administrators, and any other technicians that deal with cables

5 Structured Cabling Systems Rules of Structured Cabling for LANs look for a complete connectivity solution plan for future growth maintain freedom of choice in vendors

40 Installation technique CAT.5 installation: do and dont Please, note the relation between Categories (USA) and Classes (Europe) for UTP cable: A- B- C3 D5e E6 classcategory

41 CAT.5 Installation DONT pull cable with excessive force, as this will alter the cables insulation and transmission properties. DO pull cable using less than 25 pounds (11,3 Kg) of pull- force. CABLE TENSION UNROLLING CABLE DONT allow the cable to kink, knot or snag while pulling it off the spool or out of the box; deforming the pair-twist will alter the performance of the cable. DO use a cable pulling accessory.

42 CAT.5 Installation RUNNING & SUPPORTING CABLE DONT overstress cables by overloading …. … and DONT allow the cable hook to rip or fray the cable. DO use j-hooks or similar devices designed to support cables. minimum distance between power supply cable and network cable (parallel running) is 15 cm.

43 CAT.5 Installation DONT overstress cables by overtightering cable ties, especially to the point where crush stress is visible. DO use tie wraps loosely on large bundles. (see also Using Tie-wraps) DO use Velcro tie wraps to secure large bundles. DO use cable clamps on individual runs. RUNNING & SECURING CABLE USING WIRE CHANNELS DO use sweeping bends. DONT allow the cable to form right angles or sharp bends.

44 CAT.5 Installation STAPLING CABLE USING TIE-WRAPS DO staple by hand, or use staplers with depth stops. DONT squish cables when securing them. DO use Velcro to keep cables from becoming over-cinched. DONT chinch the cables tightly, especially to the point where crush stress is visible. DO tie-wrap the bundle loosely. DO use Velcro as a flexible and reusable alternative to plastic tie-wraps to keep bundles from cinching.

45 CAT.5 Installation REMOVING CABLE JACKET DONT remove too much cable jacket. DO retain cable jacket as close to the termination point as possible. MAINTAINING PAIR TWISTS DURING TERMINATION DONT untwist the cable pairs more than 12 mm and DONT strip cable jacket back any more than you need to. DO maintain pair twists to within 12 mm of the termination point, and the cable jacket is maintained as close to the terminations as possible.

46 Making a UTP patch cable 1.Strip off the jacket for about 2,5 cm. 2.Separate out the 4 pairs of wires 3.Untwist and organize the wires according to the proper colour code and flatten the wires (T568A or T568B). 4.Maintain the colour order and flatness of the wires, then clip their length so that a maximum of 1.2 cm of untwisted wire is present.

47 Making a UTP patch cable 6.Push the wires in firmly enough to make sure the conductors are all visible when you look at the plug from the end. 7.Inspect the colour code and jacket location to be sure they are correct. 8.Insert the plug firmly into the crimp tool and crimp down completely. 5.Insert ordered wires into RJ-45 plug; make sure jackets are inserted into plug.

55 Vocabulary cable runConduit used to run cables through a building. Also the path taken by a cable or group of cables. cable traySteel trough erected above equipment racks to support cable runs in an equipment room conduitA device used to hold, organize, and protect electrical or optical cables cross connection - A mapping between two channels or paths at a network device backboneThe main connectivity device of a distributed system. All systems that have connectivity to the backbone connect to each other antennaA device for transmitting or receiving, or transmitting and receiving signals

56 Vocabulary structured cablingis a set of standards that determine how to wire a building for data or voice communications cable pathwaysystems providing horizontal, vertical and backbone pathways from your data room to your workstations cable runwayo Ladder Rack, horizontal, vertical and backbone pathways for your computer room, telecommunications room and data center closeta cabinet or enclosed recess for telecommunications devices demarcation pointthe location within a building where the lines from the telephone company connect to the customer's lines.
