Dual function splice component for mechanical splice connector
View Patent ↗A fiber optic mechanical splice connector including a single connector element operable for providing optical fiber alignment and strain relief includes opposed splice components that define first and second grooves for receiving the bare glass portions of mating optical fibers, as well as the coated or buffered portion of at least one of the optical fibers when the splice components are biased together by an actuator. The mating optical fibers are aligned while the coated or buffered portion of one of the optical fibers is retained within the same connector element, thus eliminating positioning problems that occur when separate connector elements are utilized for fiber alignment and strain relief. The splice components may be unbiased to allow removal of at least one of the mating optical fibers without destroying the connector assembly or potentially damaging the optical fibers.
1. A fiber optic splice connector, comprising:
a ferrule having at least one stub optical fiber mounted therein;
a pair of opposed splice components defining at least one feature for receiving a bare glass portion of the at least one stub fiber, and a bare glass and a coated portion of at least one field fiber; and
a cam positioned about the pair of splice components such that rotation of the cam about the pair of splice components causes the pair of splice components to move together to align and strain relieve the at least one stub fiber with the at least one field fiber.
2. The connector according to claim 1 wherein the at least one feature comprises a first groove for receiving and aligning the bare glass portion of the at least one stub fiber and the bare glass portion of the at least one field optical fiber and a second groove for receiving the coated portion of the at least one field fiber.
3. The connector according to claim 2 wherein the first groove is sized smaller than the second groove.
4. The connector according to claim 1 wherein one splice component of the pair of splice components defines at least one keel.
5. A fiber optic splice connector comprising:
a first splice component defining a first groove for receiving bare glass portions of a stub fiber and a field fiber, and a second groove for receiving a coated portion of the field fiber;
a second splice component positioned opposite the first splice component;
one or more keels defined by at least one of the first and the second splice components; and
a cam movable between an un-actuated position in which the cam does not interfere with the one or more keels and an actuated position in which the cam does interfere with the one or more keels to urge the first and the second splice components together.
6. The splice connector according to claim 5 wherein actuation of the cam simultaneously aligns the bare glass portions of the stub fiber and the field fiber, and strain relieves the field fiber.
7. A method of providing both optical fiber alignment and retention in an optical splice between mating optical fibers, the method comprising:
providing a first optical fiber including a bare glass portion;
providing a second optical fiber including a bare glass portion and a coated or buffered portion having a diameter greater than the diameter of the bare glass portion;
disposing the first optical fiber and the second optical fiber between a pair of opposed splice components, at least one of the splice components having a first groove sized to receive and align the bare glass portion of the first optical fiber and the adjoining bare glass portion of the second optical fiber, at least one of the splice components having a second groove sized to receive and retain the coated or buffered portion of the second optical fiber;
biasing the splice components together such that the bare glass portions of the first and second optical fibers are aligned within the first groove and the coated or buffered portion of the second optical fiber is retained within the second groove.
