Structured Cabling SystemsStructured 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

Installation techniqueCAT.5 installation: do and dont

Please, note the relation between Categories (USA) and Classes (Europe) for UTP cable:A-B-C3D5eE6classcategory

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 TENSIONUNROLLING CABLEDONT 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 InstallationRUNNING & SUPPORTING CABLEDONT 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.

CAT.5 InstallationDONT 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 CABLEUSING WIRE CHANNELSDO use sweeping bends.DONT allow the cable to form right angles or sharp bends.

CAT.5 InstallationSTAPLING CABLEUSING TIE-WRAPSDO 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.

CAT.5 Installation

REMOVING CABLE JACKETDONT remove too much cable jacket.DO retain cable jacket as close to the termination point as possible.MAINTAINING PAIR TWISTS DURING TERMINATIONDONT 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.

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.

Making a UTP patch cable

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.

Insert ordered wires into RJ-45 plug; make sure jackets are inserted into plug.
