Abstract

The present disclosure relates to system and method for cleaning an end face of a bare optical fiber ( 100 ). The system and methods include inserting the end face of the bare optical fiber ( 100 ) through a layer of material ( 500 ) that includes electrospun fibers.

First claim

What is claimed is:

1. An optical fiber alignment system comprising:
an alignment device defining a fiber insertion axis extending between first and second ends of the alignment device, the alignment device also defining a fiber alignment region positioned along the fiber insertion axis;
a first optical fiber cleaning membrane positioned along the fiber insertion axis on one side of the fiber alignment region, wherein an optical fiber to be aligned penetrates through a solid and slit-free portion of the optical fiber cleaning membrane, and wherein the first optical fiber cleaning membrane has a puncturability force of no more than about 0.08 N; and
a gel disposed within the alignment device along the fiber alignment region, wherein the first optical fiber cleaning membrane aids in retaining the gel within the alignment device while an optical fiber end face pierces the first optical fiber cleaning membrane and enters the alignment device.

2. The optical fiber alignment system of claim 1 , wherein the fiber alignment region defines an alignment groove and biasing members for biasing optical fibers into the alignment groove.

3. The optical fiber alignment system of claim 1 , wherein the first optical fiber cleaning membrane includes electrospun fibers.

4. The optical fiber alignment system of claim 3 , wherein the electrospun fibers include polyurethane.

5. The optical fiber alignment system of claim 3 , wherein the electrospun fibers include a blend of polyurethane and polyethylene terephthalate.

6. The optical fiber alignment system of claim 3 , wherein the electrospun fibers of the first optical fiber cleaning membrane are sufficiently elastic to enable the cleaning membranes to recover when a piercing optical fiber is removed from the membrane.

7. The optical fiber alignment system of claim 1 , wherein the electrospun fibers of the first optical fiber cleaning membrane are electrically charged.

8. The optical fiber alignment system of claim 1 , wherein the first optical fiber cleaning membrane is between about 100 μm and about 500 μm thick.

9. The optical fiber alignment system of claim 1 , wherein the first optical fiber cleaning membrane is disposed at the first end of the alignment device, and further including a second optical fiber cleaning membrane at the second end of the alignment device, and wherein the cleaning membranes are configured to inhibit contamination from entering the alignment device through the first and second ends.

10. The optical fiber alignment system of claim 1 , wherein the first optical fiber cleaning membrane is configured to sufficiently scatter light emitted from an optical fiber received at the alignment device to inhibit damage to an eye of a user if the eye were aligned with the light with the first optical fiber cleaning membrane between the eye and the light.

11. The optical fiber alignment system of claim 1 , wherein the alignment device is disposed within an adapter between first and second ports, wherein the first optical fiber cleaning membrane faces towards the first port.

12. The optical fiber alignment system of claim 1 , wherein the alignment device is disposed within a fiber optic connector, wherein the first optical fiber cleaning membrane is configured to be penetrated by an optical fiber that is to be terminated by the fiber optic connector.

13. The optical fiber alignment system of claim 1 , further comprising a second optical fiber cleaning membrane positioned along the fiber insertion axis at an opposite side of the fiber alignment region from the first optical fiber cleaning membrane.

14. The optical fiber alignment system of claim 1 , wherein the first optical fiber cleaning membrane has a thickness of about 200 μm.

15. The optical fiber alignment system of claim 1 , wherein the first optical fiber cleaning membrane is configured to scatter light emitted from an optical fiber received at the alignment device when an end face of the optical fiber faces the first optical fiber cleaning membrane.

16. The optical fiber alignment system of claim 15 , wherein the first optical fiber cleaning membrane is configured to scatter the light sufficiently to heavily attenuate the light.
