I'm assuming you are referring to Category 5 cabling and not coax, fiber, etc. 1. Rules of data Cabling? * Maximum length of 100 meters (about 300 feet) * Avoid sources of EMI (Electro-Magnetic Interference) (high voltage lines, electric motors, etc.) * Avoid sharp edges that can damage the cable * Do not exceed the bend radius of the cable (for Cat5, it's about 1, or a 2 coil) * Don't stress the cable. Do not stretch by putting more than 25 lbs of tension on the cable. * When terminating UTP (Unshielded Twisted Pair) cables, preserve as much of the twists as possible. This helps prevent cross-talk 2. Importance of reliable cabling? * Provides reliable data flow * Reduces cost due to replacement and lost data 3. Cause of poor cabling? * Exposing cable to: - excessive heat - weather - excessive cold - Electro-Magnetic Interference * improper installation * improper termination 4. Types of communications media? Copper phone lines (2-pair twisted) Coaxial UTP (Unshielded Twisted Pair) STP (Shielded Twisted Pair) Fiber Optic Microwaves Wireless (radio)
