STRUCTURED CABLING Final Exam Compendium A. Memo

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

3 Objectives Structured cabling systems Terminology Passive Devices
Cross Connect technology Documentation Installation technique 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 don’t class category A - B - C 3 D 5e E 6 Please, note the relation between Categories (USA) and Classes (Europe) for UTP cable:

DON’T pull cable with excessive force, as this will alter the cable’s insulation and transmission properties. DO pull cable using less than 25 pounds (11,3 Kg) of pull-force. UNROLLING CABLE DON’T 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.

CAT.5 Installation RUNNING & SUPPORTING CABLE DON’T overstress cables by overloading …. … and DON’T allow the cable hook to rip or fray the cable. minimum distance between power supply cable and network cable (parallel running) is 15 cm. DO use j-hooks or similar devices designed to support cables.

CAT.5 Installation RUNNING & SECURING CABLE DON’T 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. USING WIRE CHANNELS DON’T allow the cable to form right angles or sharp bends. DO use sweeping bends. DO use cable clamps on individual runs.

DON’T squish cables when securing them. DO staple by hand, or use staplers with depth stops. DO use Velcro to keep cables from becoming over-cinched. USING TIE-WRAPS DON’T 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.

CAT.5 Installation REMOVING CABLE JACKET DO retain cable jacket as close to the termination point as possible. DON’T remove too much cable jacket. MAINTAINING PAIR TWISTS DURING TERMINATION DON’T untwist the cable pairs more than 12 mm and DON’T 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
Strip off the jacket for about 2,5 cm. Separate out the 4 pairs of wires Untwist and organize the wires according to the proper colour code and flatten the wires (T568A or T568B). 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
Insert ordered wires into RJ-45 plug; make sure jackets are inserted into plug. Push the wires in firmly enough to make sure the conductors are all visible when you look at the plug from the end. Inspect the colour code and jacket location to be sure they are correct. Insert the plug firmly into the crimp tool and crimp down completely.

54 Vocabulary layout A proposed or actual arrangement or allocation of equipment ground An intentional or accidental connection between an electric circuit or its housing and the ground (earth) fiber optics Thin filaments of glass through which light beams are transmitted over long distances and which can carry enormous amounts of data cable A single wire or group of individual wires in a single sheath cable riser Cable running vertically in a multi-story building to serve the upper floors.

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

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