Cabling Rules

Try to avoid running cables parallel to power cables. Do not bend cables to less than four times the diameter of the cable. If you bundle a group of cables together with cable ties (zip ties), do not over-cinch them. You should be able to turn the tie with fingers. Keep cables away from devices which can introduce noise into them. Here's a short list: copy machines, electric heaters, speakers, printers, TV sets, fluorescent lights, copiers, welding machines, microwave ovens, telephones, fans, elevators, motors, electric ovens, dryers, washing machines, and shop equipment. Avoid stretching UTP cables (tension when pulling cables should not exceed 25 LBS). Do not run UTP cable outside of a building. It presents a very dangerous lightning hazard! Do not use a stapler to secure UTP cables. Use telephone wire/RJ6 coaxial wire hangers which are available at most hardware stores.

Fiber Optic Connectors

Terminates the fibers

Connects to other fibers or transmission equipment

Fiber Patch Cords & Pigtails

Ends are typically either SC or ST

Pigtails have connectors on only one side and Patch Cords have it on both sides.

Pigtails are spliced to the fiber to terminate the fiber

Patch Cord connects switches to the Fiber cable

Outside Plant

Fiber is blown in HDPE Pipes, 1 m deep.

The HDPE pipes is covered with sand and brick lining

Fiber Roles are typically 2 Km. Fiber cables are spliced using Jointers

Faults like fiber cut are located using OTDR (Optical Time Domain Reflectometer)
