Angle polishing systems and methods for multi-ferrule optical connectors
Systems and methods for angle polishing of the end faces of a plurality of optical connectors are provided. Systems are provided that include a connector defining a longitudinal axis, and at least two ferrules mounted with respect to the connector and arranged in a side-by-side orientation. The end faces of the connectors are movable relative to the connector and such movement facilitates lateral orientation of the angle polished end faces of the ferrules relative to the connector when in the mating position. Various mechanisms and methods for facilitating movement of the ferrules relative to the connector are disclosed to achieve the desired lateral polish orientation of the ferrule end faces.
1. A device for angle polishing of ferrules, the device comprising:
a sleeving element including an interior configured to receive at least two ferrules of a connector, the at least two ferrules including a first ferrule and a second ferrule; and
an offset feature disposed within the interior of the sleeving element, the offset feature configured to engage the first ferrule or the second ferrule to move the first or second ferrule against a bias of a spring associated with the first or second ferrule;
wherein engagement of the first ferrule or the second ferrule with the offset feature results in a coplanar orientation of end faces of the first and second ferrules along a plane angled relative to a longitudinal axis of the connector.
2. The device of claim 1 , wherein the first ferrule and the second ferrule are disposed in a side-by-side orientation and movable relative to a connector body of the connector.
3. The device of claim 1 , wherein the sleeving element includes a first side and a second side, and the sleeving element is configured to receive the first ferrule and the second ferrule from the first side and within the interior such that the first and second ferrules extend from the second side of the sleeving element.
4. The device of claim 1 , wherein in the coplanar orientation, the end faces of the first and second ferrules are offset from each other relative to a connector body of the connector.
5. The device of claim 1 , wherein the coplanar orientation of the end faces of the first and second ferrules is a polishing position of the end faces.
6. The device of claim 1 , wherein the plane is angled by 8 degrees relative to the longitudinal axis of the connector in the coplanar orientation.
7. A system for angle polishing, comprising:
a connector including at least two ferrules, the at least two ferrules including a first ferrule and a second ferrule, and wherein the connector includes a first spring biasing the first ferrule, and a second spring biasing the second ferrule; and
a sleeving element including an interior configured to receive the at least two ferrules of the connector, the sleeving element including an offset feature disposed within the interior of the sleeving element, the offset feature configured to engage the first ferrule or the second ferrule to move the first or second ferrule against a bias of the respective first or second spring;
wherein engagement of the first ferrule or the second ferrule with the offset feature results in a coplanar orientation of end faces of the first and second ferrules along a plane angled relative to a longitudinal axis of the connector.
8. The system of claim 7 , wherein the first and second ferrules are configured to move relative to a connector body of the connector.
9. The system of claim 7 , wherein removal of the sleeving element from the connector disengages the first ferrule or the second ferrule.
10. The system of claim 9 , wherein disengagement of the first ferrule or the second ferrule allows the first and second springs to bias the respective first and second ferrules distally into a lateral orientation.
11. The system of claim 10 , wherein the lateral orientation defines a mating position in which the end faces of the first and second ferrules are aligned along a plane perpendicular to the longitudinal axis of the connector.
12. The system of claim 7 , wherein the plane is angled by 8 degrees relative to the longitudinal axis of the connector in the coplanar orientation.
13. A method of angle polishing ferrules, the method comprising:
positioning at least two ferrules of a connector within an interior of a sleeving element, the sleeving element including an offset feature disposed within the interior of the sleeving element, and the at least two ferrules including a first ferrule and a second ferrule; and
engaging the first ferrule or the second ferrule with the offset feature of the sleeving element to move the first or second ferrule against a bias of a spring associated with the first or second ferrule, wherein engagement of the first ferrule or the second ferrule with the offset feature results in a coplanar orientation of end faces of the first and second ferrules along a plane angled relative to a longitudinal axis of the connector.
14. The method of claim 13 , wherein the sleeving element includes a first side and a second side.
15. The method of claim 14 , wherein positioning the first and second ferrules within the interior of the sleeving element comprises inserting the first and second ferrules into the interior of the sleeving element from the first side such that the first and second ferrules extend from the second side of the sleeving element.
16. The method of claim 15 , comprising polishing the end faces of the first and second ferrules extending from the second side of the sleeving element.
17. The method of claim 13 , comprising removing the first and second ferrules from the sleeving element to disengage the offset feature from the first ferrule or the second ferrule.
18. The method of claim 17 , wherein disengagement of the first ferrule or the second ferrule allows the first and second springs to be biased distally by springs of the connector into a lateral orientation.
19. The method of claim 18 , wherein the lateral orientation defines a mating position in which the end faces of the first and second ferrules are aligned along a plane perpendicular to the longitudinal axis of the connector.
20. The method of claim 13 , wherein the plane is angled by 8 degrees relative to the longitudinal axis of the connector in the coplanar orientation.
