1. An optical fiber connector assembly configured to couple a proximal end of a guidewire assembly having a first optical fiber to a second optical fiber, the connector assembly comprising:
a connector housing having a proximal end, a distal end, a bore extending therethrough;
a distal ferrule defining a distal ferrule lumen configured to receive the first optical fiber, the distal ferrule positioned within the bore and configured to couple to a tube, the tube coupled to a proximal end of the guidewire assembly;
a proximal ferrule positioned within the bore and abutted against the distal ferrule, wherein the proximal ferrule includes a proximal ferrule lumen configured to receive the second optical fiber, wherein an end of the second optical fiber is configured to align with and butt against an end of the first optical fiber;
a split sleeve disposed about at least a portion of the distal ferrule and at least a portion of the proximal ferrule; and
a capillary tube having a capillary lumen, the capillary tube configured to be positioned within the distal ferrule lumen, wherein the capillary lumen is configured to receive the first optical fiber, wherein the capillary tube is bonded to the distal ferrule.
