The most critical step in terminating UniCam Connectors on fan-out cable is to leave 4 mm of the 250 µm coating extending beyond the 900 µm fan-out tubing. The 4 mm will allow the fiber to piston in the fan-out tubing and still maintain the fiber mating in the splice area of the UniCam Connector. Refer to Sections 3.5 (MT-RJ), 4.5 (LC) and 5.6 (SC, ST Compatible, FC) of SRP-006-150 for further instructions.

The difference between a SR and JR UniCam LC Connector is that JR does not have a ferrule with a spring. In other words, you can’t push on the ferrule to make it retract into the connector housing. The old LC Junior part number is 95-XXX-98 and the new LC Senior will be 95-XXX-99. Refer to the UniCam Pretium™-Performance Multimode Connectors, LC, SC, ST® Compatible specification sheet for more information.

In the earliest days of optical fiber jointing the sophisticated manufacturing techniques now associated with demountable connectors were not available. Instead existing components or technology had to be used or modified to provide an acceptable level of insertion loss. The most obvious method was to use a machined V-groove as an alignment tool and to secure the two fiber ends within metal tubes or ferrules in such a way as to ensure acceptable performance. It is relatively easy to produce V-grooves and tubes to the required tolerances: the difficult task was to align the fibers within the tubes themselves. These

3M Introduces No-Polish Quick Termination Field Installable Fiber Optic Connector 3M added a new, no-polish fiber optic connector to its fiber connector family. The device enables fast, on-site installation of singlemode and multimode connections. The 3M no-polish connector utilizes 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. Fiber installers have historically installed connectors using field-polishing. With the factory-polished ferrule assembly and a mechanical splice, the 3M
