3M Co.'s single-mode multifiber system initiates its OGI line of products. A high-density panel mount and backplane feedthrough system, it includes multifiber cable assemblies, multifiber ruggedized fan-out assemblies, and panel-mount, daughter-card and backplane couplings. The panel-mount couplings come in single- and four-port versions, and the backplane couplings hold four connectors, each of which contains eight- or 12-fiber ferrules in a ½-in. nominal interface. Metal components in the couplings boost electromagnetic interference shielding, and independent shutters increase eye safety. Cable assemblies use an OGI connector on one end and discrete connectors on the breakout end. They are suitable for applications requiring high pull strength. A method that will enable cleaning OGI connectors after installation is under development.
