3M Announces No-polish Connector

3M this week added a new, no-polish connector to its fiber connector family. The device enables fast, on-site installation of single-mode and multimode connections, say company representatives.

The 3M no-polish connector uses a one-piece, pre-assembled design, eliminating field polishing and loose parts. Systems integrators and installers for communication companies and private networks will find this connector an easy way to make field terminations that improve cable management inside buildings or in the outside plant, contends the company.

Fiber installers have historically installed connectors using field polishing. With the factory-polished ferrule assembly and a mechanical splice, the 3M no-polish connector can be installed quickly—without electrical power—using a simple tool, resulting in little setup time and capital investment.

A bell-shaped boot is permanently attached to the connector body so there is no chance of losing it or forgetting to install it before inserting the fiber. The bell feature maintains the minimum fiber bend radius for excellent strain relief, 3M representatives say.

The easy-to-use assembly tool allows the installer to align a prepared fiber in the connector and activate the splice and buffer clamp using the same tool. Finger grips on the tool make it easy to handle even without a flat work surface. According to 3M, a connector installation can be completed in less than two minutes.
