Connectors and Information

The cable exists in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking and is suited for reliable connections with insulation piercing connectors, but makes unreliable connections in insulation-displacement connectors. The solid form is less expensive and makes reliable connections into insulation displacement connectors, but makes unreliable connections in insulation piercing connectors. Taking these things into account, building wiring (for example, the wiring inside the wall that connects a wall socket to a central patch panel) is solid core, while patch cables (for example, the movable cable that plugs into the wall socket on one end and a computer on the other) are stranded. Outer insulation is typically PVC or LSOH.

CHARACTERISTICS of Category 5 Wire
Bending radius
Most Cat 5 cables can be bent at a radius approximately 4 times the diameter of the cable.

Maximum Cable Segment Length
According to the ANSI/TIA/EIA standard for category 5e cable, (TIA/EIA 568-5-A[5]) the maximum length for a cable segment is 100 meters (328 feet). If longer runs are required, the use of active hardware such as a repeater, or a switch, is necessary.[6] [7] The specifications for 10baseT networking specify a 100 metre length between active devices. This allows for 90 metres of fixed cabling, two connectors and two patch leads of 5 metres, one at each end. In practice longer lengths are possible. (See Ethernet over twisted pair which states that 150 m is often considered to be the maximum working length.) Experiments show that a full 305 metre drum of cable is well above the practical limit, but that reliable transmission with 200 m is often possible.
