Abstract
A fiber optic connector has a crimp body that allows for a heat shrink tube to be abutted to the crimp band used with the crimp body or dispose underneath the crimp band to allow for the use with a VSFF fiber-optic connector.
Claims15
A very small form factor (VSFF) fiber optic connector comprising:
- a main body having a housing supporting at least one fiber-optic ferrule, the at least one fiber-optic ferrule having at least one optical fiber terminated therein;
- a crimp body extending rearwardly from the housing and forming an opening to receive the at least one optical fiber;
- a plurality of securing features distributed circumferentially around a rear portion of the crimp body to engage an aramid yarn of a cable jacket containing the at least one optical fiber, the plurality of securing features having openings between at least two of the plurality of securing features, the openings also distributed circumferentially at the rear portion at a same longitudinal location;
- a crimp band disposed over a portion of the crimp body, the crimp band securing the aramid yarn of the cable jacket to the crimp body;
- and
- a heat shrink disposed over the securing features and at least a portion of the cable jacket rearward of the opening.

A process for terminating one or more optical fibers in a fiber-optic connector, the process comprising:
- providing a connector housing and a crimp body rearward of the connector housing;
- providing a cable jacket with aramid yarn and at least one optical fiber therein;
- placing a boot, a heat shrink and a crimp band over the cable jacket;
- inserting the at least one optical fiber through an opening formed by the crimp body at a rear end of the crimp body and terminating the optical fiber into a fiber optic ferrule supporting the at least one optical fiber;
- placing the aramid yarn through one or more openings between a plurality of securing features on the crimp body;
- positioning the crimp band over the crimp body upon completion of a curing process with the aramid yarn distributed evenly around the crimp body;
- covering the aramid yarn exposed rearward of the crimp band with the heat shrink tube, wherein the heat shrink tube is engaged to the plurality of securing features;
- heating the heat shrink tube over the exposed aramid yarn at a temperature to shrink onto the crimp body without engaging the crimp band;
- and
- sliding the boot over the cable jacket, the aramid yarn, the crimp body, the crimp band and the heat shrink tube for engagement with the connector housing.
