C.2.

Cable Pulling – General guidelinesWhen cable is received at the job site, the cable length is verified to ensure the cable will reach

between the end points. Both ends of the cable will also be verified in terms of the footage markings

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 24 of on the outer jacket and the computation of the actual length of the jacket whenever available. The

cable shall be identified, labeled, and the shop drawings updated to reflect the work operation.

A good cable pulling setup means all materials are in place so the cables can be handled properly and

safely. Specialized equipment capable of holding large reels will be used as and when needed.

Smaller equipment, such as cable trees, will also be used to handle the many reels of cable

containing low pair count cable.

The pathway of a cable will checked first to be free of sharp bends and turns. The manufacturer’s

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 25 of recommended pulling tension and minimum bend radius (while under tension) shall not be

exceeded. The use of cable lubricants as and when deemed necessary will significantly reduce friction

and speed up cable installation especially within the conduits. The lubricant will be selected based on

cable manufacturer’s recommendations.

When the large, high pair count copper cables are installed in conduits, the pulling of the cable

places significant tension on the conduit. A winch can be used if required in this high pair count

placing operation.

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 26 of Communication with co-workers is essential in every cable pull. Each of the co-workers will be pre -

pared to alert the person pulling the cable, to ensure the cable is traversing the route smoothly

without twisting, or getting bound up.

Pulling Horizontal cable in conduits

Horizontal cable is installed between the telecommunications room and work area outlets. Cable

shall not be bent. Should the cable be damaged during installation, do not attempt to repair,

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 27 of instead replace the entire cable.

The cables and their reels will be labeled prior to pulling cable into place. It is easier to identify

and label the cables before they are pulled through the conduit.

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 28 of Pulling Horizontal cable in open ceiling

The procedure for cable installation in open ceilings is different from that in conduits. Cables shall

be supported whenever available by suitable cable trays and cable baskets.( A maximum of 60

Cables can be accommodated in a cable tray of 100x50mm).

Pulling backbone in vertical pathways from top to bottom

Cable is generally easier to install from the top down rather than from the bottom up because

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 29 of gravity helps with the pull. When pulling cable from top down, a reel brake will be used. A reel

brake is a mechanical device used to stop or slow a freewheeling reel, thus keeping it from

unreeling too fast due to gravity. In the room where the cable will enter the vertical pathway, a

bull wheel will be used to ensure that the jacket is not damaged as it enters the pathway.

Pulling – Horizontal

Horizontal Cable is used to connect telecommunications rooms to the different end users outlets.

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 30 of In the room where the cable will enter the horizontal, a bull wheel may be used to ensure that

the jacket is not damaged as it enters the pathway. A pull wire will be used and the cable will be

pulled from end to end by taking all necessary precautions as per the requirements of the cable

manufacturer. Inspection Materials located near the bends will be closely monitored during cable

pulling in order to avoid cable mishandling.

Precautions

To verify receipt of undamaged cable, while the cable is still on the reel, the installer should verify

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 31 of that there is continuity with the cable still on the reel. For copper cable, continuity can be verified

by use of an ohm-meter.

For optical fiber cable, continuity can be verified by shining a light source (e.g., flashlight) into the

fiber strands or using a power meter or optical time domain reflectometer (OTDR).

Pulling backbone – Vertical

For optical fiber pulling, common sense is the best guideline to follow. Some of the primary

installation concerns that should be addressed during the installation of an optical fiber cabling

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 32 of system are:

Tensile Load / Installation Pull

Bend Radius( In general the max acceptable bend for Cat 6A copper cable is 4 times its

outer diameter & for Fiber 10 times the outer diameter.

The maximum length of a Cat6A permanent link is 90Meters. The number of bends in a link is not

defined as long as the bends maintain the bend radius criteria)

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 33 of The installer shall follow the manufacturer’s recommendations. During pulling, installer should

avoid crushing the cable by stepping on it or having it out in the open when man or machine may

trample it. Even though the crush resistance of the optical fiber cabling is usually around 700%

greater than that of CAT6 A UTP, one must remember that it is still made of glass.

Cable Termination

Cable termination involves the organizing of cables by destination, forming and dressing cables, and

labeling, as well as actually creating a connection with a copper or fiber conductor.

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 34 of Cable termination preparation not only improves the quality of the job but also decreases the

amount of time required for termination.

The performance of pre-termination functions involves organizing the cable by destination. Cable to

be terminated should be placed at the point of termination and must also be identified to ensure it is

terminated in the designated position. Cable connection is not complete until all terminations are

identified and labeled.

Crosstalk is associated with copper balanced twisted-pair cabling and an issue of which the installer

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 35 of must be aware. This issue can be mitigated by allowing cables to have a more natural lay rather than

forming tight bundles and allowing cables to be run next-and-parallel to each other. While forming

and dressing the cable at the point of termination may be visually pleasing, doing so for longer dis-

tances, such as within a cable tray, may lead to alien crosstalk performance issues. Separation of

balanced F/UTP cables should follow the guidance of ANSI/TIA568-B.

PROJECT MANAGER



PROJECT MANAGER



Copper Termination

Copper terminations are used for balanced twisted-pair cabling and the use of insulation

displacement contact (IDC) is recommended. When terminating balanced twisted-pair copper

cable:

• Remove only as much cable jacket as is required for termination and trimming.

• Follow the manufacturer’s instructions for mounting, termination, and cable management.

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 38 of • Minimize the amount of untwisting in a pair as a result of termination to connecting

hardware. For untwisting cabling, maintain pair twists as close as possible to the termination

point.

The T568A and the optional T568B wiring schemes (see Figure 19) are recognized for use with

horizontal copper cable. Only one of the wiring schemes shall be used in a project. (TIA568B)

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 39 of Fiber Termination

In the current project, there are two specific types of optical fiber used: multimode and

single-mode. Each specific type of fiber has its own characteristics. Multimode optical fiber has an

outside diameter of 125 µm. The glass core of the fiber, which carries the optical signal, has a

diameter of 50 µm. Single-mode optical fiber has an outside diameter of 125 µm. The glass core

of the fiber, which carries the optical signal, has a diameter of 8-9 µm.

Optical fiber cores must be precisely aligned between connecting cables to ensure that the

PROJECT MANAGER


METHOD STATEMENT FOR INSTALLATION Page No. : Page 40 of maximum transfer of light energy is obtained. In this project, pigtails will be used for termination.

Splicing will be done by using a fusion splicing method as directed by cable manufacturer.
