STP CAT6A RJ45 T568A T568B Keystone Jack, 180 degree type wiring with dust cover installation. What is a keystone jack? A keystone jack is a female connector used in data communications, particularly for local area networks LANS, usually mounted in a wall plate or patch panel. T568A and T568B are the two wiring standards for an 8P8C modular connector, RJ45 connector, permitted under the TIA/TIA-568A-A wiring standards color code schema. The only difference between T568A vs T568B is the oring and green wire pairs ( pair 2 & pair 3) are interchanged. Both T568A & T568B wiring schemas are labeled on the housing of keystone jack. The CAT5E and CAT6 wiring diagrams with corresponding colors are twisted in the network cabling and should remain twisted as much as possible when terminating them at a jack. Because we take great pride in our quality control procedures and our commitment to quality our keystone jack's line meets all requirements for EIA/TIA and also inspected an…
