Loose tube fiber optic cable assembly
A fiber optic connector assembly comprises a ferrule assembly including a ferrule and a hub. The ferrule has a distal end and a proximal end. The proximal end of the ferrule is mounted to the hub. The ferrule defines a fiber passage that extends through the ferrule from the proximal end to the distal end. The fiber optic assembly further comprises an optical fiber having an end portion potted within the fiber passage of the ferrule. A loose tube receives the optical fiber. The loose tube has a distal end positioned inside the hub and defines a venting opening that starts at the distal end of the loose tube and extends proximally along a length of the loose tube.
1. A fiber optic connector assembly, comprising
a ferrule assembly including a ferrule and a hub, the ferrule having a distal end and a proximal end, the proximal end of the ferrule being mounted to the hub, the ferrule defining a fiber passage that extends through the ferrule from the proximal end to the distal end;
an optical fiber having an end portion potted within the fiber passage of the ferrule; and
a loose tube that receives the optical fiber, the loose tube having a distal end positioned inside the hub;
a venting opening having a length that extends proximally along the loose tube, the venting opening having an open end positioned adjacent to the proximal end of the ferrule and a closed end positioned outside of the hub, and the venting opening having edges that converge as the venting opening extends along the loose tube such that the open end of the venting opening is wider than the closed end of the venting opening.
2. The fiber optic connector assembly according to claim 1 , wherein the venting opening extends from the distal end of the loose tube to a location which is outside the hub.
3. The fiber optic connector assembly according to claim 1 , wherein the venting opening has a triangular shape when viewed from above in plan view.
4. The fiber optic connector assembly according to claim 1 , wherein the length of the venting opening is longer than a distance defined between a pocket of the hub and a proximal end of the hub.
