EIA/TIA 568 standard A

a standard for building cable for commercial buildings that support data networks, voice and audio

corssover EIA/TIA 568 A and B cables

directly connects two computing devices or two switches together

What is a cable plan and why would you want one?

documentation and paperwork that shows where and what each cable is and what it does. Good for futrue reference and organization

why use a patch panel

it will help keep it organized as well as make it easier to move, add, or change cabling infrastructure

EIA/TIA 568 standard B

no different from 568 A but green and organe wire are switched

EIA/TIA 568 standard B twisted pari order from left ot right

orange/white, orange, green/white, blue, blue/white, green, brown/white, brown

physical media

physcial meaterial used to transmit information in data communications, normally in the form of copper or glass

improper cabling can lead to....

speed loss, irregular network cable issues, and poor data transmission

strippers

strip cabling of csing

TIA 530 A

supports balanced and unbalanced trnasmission rates

punch down tool(impact tool)

terminate the wire

TIA 232 F

Serial port not taken over by usbs and ethernets

patch panel

a device or unit featuring a number of jack, usually same or similar type, for the use of connectin gan routing circuits for monitioring, interconnecting, and testing circuits in a convienient, flexible manner

loop-back EIA/TIA 568 A and B cables

a plug used to test physical ports to identify network issues

roll-over EIA/TIA 568 A and B cables

conenct the workstation to the console port of the switch

EIA/TIA 568 standard C

covers systems/components, topology and transmission medium specs, and testing for fiber, twisted pair and coax

where should labels be applied on a cable?

each cable and each pathway on each end, the termination points on both ends of the cable, all jack, connectors and block hardware on either the outlet or panel

RJ45 crimper

form a physical bond of cables

EIA/TIA 568 standard A twisted pair order from left to right

green/white, green, green/orange, blue, blue/white, orange, brown/white, brown

shielded cables

reduces electrical noise and protects wires in the cable but hey are expensive and take more time

unshielded cables

they are more hazardous but they are cheaper and take less time

should labeling match the project drawing?

yes, labeling should be logical and consisen, across all locations, mathching the project drawings
