Cablesys, CBS, Category 6 feed through in-line coupler is designed to connect two CAT 6 patch cords together with no termination required. The coupler has 8-position 8-conductor RJ-45 keystone jacks on both ends. The contacts within each port are made using high quality phosphor bronze plated with 50-60 micro-inch nickel and then plated with 50 micro inches of gold. The insertion force of the eight contacts is 900 GMS. The retention strength is 7.7 KGS between jack and plug. The keystone jack can withstand 750 insertion and removal cycles from an RJ45 CAT6 patch cable. CBS CAT6 keystone coupler is built with PCB technology to provide maximum performance and superior signal quality. The feed-thru CAT 6 coupler is factory tested to exceed ANSI/TIA/EIA-568-B.2 Category 6 connecting hardware requirements without degradation in performance.
