Cat5E, Cat6, Computer Jack - Variety of colors to choose from
RJ45 keystone are 8P8C (8 position 8 connection) jacks that can snap into a faceplate so that an RJ45 mod plug can be plugged into them. They are punched down using a 110 blade on a punch down tool in either the A pattern or the B pattern. Either A or B pattern can be used as long as the pattern on one end of the cable matches the pattern on the opposite end of the cable, though the B pattern is most popular in commercial use. CableSupply.com carries RJ45 keystone jacks that come in Cat5e, Cat6, or Cat6a. It is important to use the appropriate jack with the correlating cable; if a Cat5e jack were used on a Cat6 cable the connection would still work, however, the capabilities would be that of the lowest capabilities of the hardware. For example: a Cat5e Ethernet cable on a Cat6 jack would bring it to the capabilities of a Cat5e jack.
When stripping a cable to be punched down on a RJ45 jack, be sure to pull on the string within the cable to expose new cable that has not been potentially nicked by the data scissors or cable stripper. Next you will untwist the pairs and match up the wires to the color code printed on the side of the RJ45 keystone jack, either color code A or color code B. Don’t untwist the pairs too much because the twist in the pairs helps protect against alien crosstalk. Make sure that the color code on both ends of the cable match or there will not be a proper connection. There is a plastic cover that protects the exposed cables from dust and from being pulled out that can snap on top of the punched down cables. The RJ45 keystone jack can snap into a faceplate that can then be screwed into a P-ring, or plaster ring, on a wall. Keystone jacks also fit perfectly into surface mount boxes as well as unpopulated patch panels.
