We know it's often necessary to insert 6-position (6P) plugs into RJ-45 8-position (8P) connectors. When the outside "shoulders" of the 6P plug push against pins 1 and 8 in an 8P connector, the pins may be bent beyond their ability to return to normal position. When 8P plugs are later plugged in, open or intermittent-open circuit conditions may occur. Denying this reality in the design and development of jack systems ultimately leads to the development of an inferior product.

Industry standards such as ANSI/TIA-1096-A and ANSI/TIA-568 do not adequately address the issue. Fortunately, Leviton patented Retention Force Technology™ (RFT), found in Atlas-X1® and eXtreme® Jacks and select patch panels, features a patented polymer spring that supports jack tines and increases their resistance to strain and damage.

For example, when a 4- or 6-pin plug or probe is inserted into any Leviton jack or patch panel with RFT, the spring returns tines to their pre-stress location and protects against long-term damage. Because insertion of 4- or 6-pin plugs into 8-pin connectors is common, we plan, design, build, and test for this real-world occurrence.

Damaged jacks can cost an estimated $150 per replacement. Leviton jacks with RFT provide long-term reliability and performance saving valuable time and money by avoiding these costly repairs.
