Optical fiber connector
An optical fiber connection system includes a first and a second optical fiber, each with end portions that are terminated by a first and a second fiber optic connector, respectively. A fiber optic adapter connects the first and the second fiber optic connectors. The fiber optic adapter includes a housing and a fiber alignment apparatus. The fiber alignment apparatus includes V-blocks and gel blocks. Each of the fiber optic connectors includes a connector housing and a sheath. The end portions of the optical fibers are positioned beyond distal ends of the respective connector housings. The sheath is slidably connected to the connector housing and slides between an extended configuration and a retracted configuration. The sheath covers the end portion of the respective optical fiber when the sheath is at the extended configuration and exposes the end portion when at the retracted configuration. The end portions of the optical fibers are cleaned when slid between the V-blocks and the gel blocks.

10. The fiber optic connector of claim 9 , wherein the housing includes a bore and a shoulder, wherein the sheath and the ferrule adaptation are positioned within the bore, and wherein a shoulder of the ferrule adaptation abuts the shoulder of the bore when the ferrule adaptation converts the fiber optic connector into the SC compatible connector.
11. The fiber optic connector of claim 10 , further comprising a spring that biases the sheath toward the extended configuration, wherein the spring urges the distal end of the sheath and the second end of the ferrule adaptation together, and wherein the spring also urges the shoulder of the ferrule adaptation and the shoulder of the bore together when the ferrule adaptation converts the fiber optic connector into the SC compatible connector.
12. The fiber optic connector of claim 10 , wherein the ferrule adaptation may be assembled into the bore through the distal end of the housing with a snap-fit connection.
13. The fiber optic connector of claim 12 , wherein the snap-fit connection includes at least one resilient member at the first end of the ferrule adaptation.
14. A fiber optic connector for terminating an optical fiber, the fiber optic connector including a ferrule-less configuration and a ferruled configuration, an end portion of the optical fiber adapted to be directly held by alignment features of a first fiber optic adapter when the fiber optic connector is in the ferrule-less configuration, and the end portion of the optical fiber adapted to be held by alignment features of a second fiber optic adapter via a ferrule of the fiber optic connector when the fiber optic connector is in the ferruled configuration, the fiber optic connector comprising:
a housing extending between a proximal end and a distal end, the housing adapted to attach to the optical fiber;
