Standard Patch Cable Wiring

Cat 5 is also used to carry other signals such as telephony and video.

Standard patch cable wiring.

Therefore a 568b patch cable should work fine on a 568a cabling system and visa versa. So a patch cable is often called a straight through cable. Cut all of the wires at a perfect 90 degree angle from the cable 1 2 inch from the end of the cable jacket. Bring all of the wires together as closely as possible.

The tia eia 568 a specifies two wiring standards for an 8 position modular connector such as rj45. T 568b straight through ethernet cable. Devices of different types e g a switch connected to a computer or a switch to a router are connected with patch cords. If you require a cable to connect two ethernet devices directly together without a hub or when you connect two hubs together you will need to use a crossover cable instead.

It is important to wire according to a standard to get proper performance from the ethernet cable. In other words patch cable does not change or swap along its way. Hold the grouped and sorted wires together tightly between the thumb and the forefinger. Cables that are terminated with differing standards on each end will not function normally however mixing t568a terminated patch cords with t568b terminated horizontal cables or the reverse will not produce pinout problems in a facility although it may slightly degrade signal quality this effect is marginal and certainly no greater than.

The two wiring standards t568a and t568b vary only in the arrangement of the colored pairs. Patch cords are usually produced in many different colors so as to be easily distinguishable and are. Category 5 cable cat 5 is a twisted pair cable for computer networks since 2001 the variant commonly in use is the category 5e specification cat 5e the cable standard provides performance of up to 100 mhz and is suitable for most varieties of ethernet over twisted pair up to 1000base t gigabit ethernet. Virtually all pre assembled patch cables are wired to the b standard.

For patch cables 568 b wiring is by far the most common wiring method. So both side connector a and connector b of patch cable have wire arrangement with same patch cable colors as shown in the following picture. Just for completeness i ll list out the cable colour order for the other ethernet cable plug standard t568a. Use the 568 b wiring scheme on both ends for a standard patch cable.

Both ends use the same wiring standard. Of course if you want to make a cross over cable then you can make the cable wiring to the different standard alignments at each plug ie. Both the t 568a and the t 568b standard straight through cables are used most often as patch cords for your ethernet connections. One end will have the t568b and the other the.
