Abstract

A cleaning apparatus ( 100 ) for cleaning an endface ( 202 ) of an optical fiber contained within an interface device ( 200 ) is provided. The cleaning apparatus includes a housing ( 110 ) having an interface portion ( 116 ) adapted to be received by the interface device. The cleaning apparatus also includes at least a first nozzle ( 126 ) operable to deliver a pressurized gas and a solvent upon the endface to aid in the removal of contaminants on the endface. A method for cleaning an endface of an optical fiber contained within an interface device is also provided. The method comprises the steps of inserting an interface portion within the interface device so as to position a nozzle in proximity to the endface of the interface device. The method further comprises the steps of directing a pressurized gas through the nozzle toward the endface and intermixing a solvent with the pressurized gas.

Claims (12)

1. A cleaning apparatus comprising:

(a) a nozzle assembly adapted to be positioned in proximity to an endface of an optical fiber associated with a fiber optic connector in a bulkhead adaptor; and

(b) a delivery system coupled in fluid communication with the nozzle assembly, wherein the delivery system is adapted to deliver a liquid upon the endface via the nozzle assembly to aid in removal of contaminants on the endface and also adapted to deliver a gas substantially free of the liquid upon the endface via the nozzle assembly to aid in removal of the liquid from the endface;

wherein the delivery system is configurable between a first position in which the liquid is permitted to be delivered through the nozzle assembly and a second position in which a spring biases a fluid delivery valve in a closed position such that the liquid is impeded from being delivered through the nozzle assembly while the gas is permitted to be delivered from the nozzle assembly.

2. A cleaning apparatus comprising:

(a) a nozzle assembly adapted to be positioned in proximity to a endface of an optical fiber associated with a fiber optic connector in a bulkhead adaptor;

(b) a delivery system coupled in fluid communication with the nozzle assembly, wherein the delivery system is adapted to deliver a liquid upon the endface via the nozzle assembly to aid in removal of contaminants on the endface and also adapted to deliver a gas substantially free of the liquid upon the endface via the nozzle assembly to aid in removal of the liquid from the endface; and

(c) a vacuum port coupled to the nozzle assembly and oriented to be disposed in proximity to the endface, wherein the vacuum port is adapted to be coupled to a vacuum source such that a vacuum may be applied to the endface during cleaning of the endface.

3. A cleaning apparatus comprising:

(a) a nozzle assembly adapted to be positioned in proximity to a endface of an optical fiber associated with a fiber optic connector in a bulkhead adaptor;

(b) a delivery system coupled in fluid communication with the nozzle assembly, wherein the delivery system is adapted to deliver a liquid upon the endface via the nozzle assembly to aid in removal of contaminants on the endface and also adapted to deliver a gas substantially free of the liquid upon the endface via the nozzle assembly to aid in removal of the liquid from the endface; and

(c) a biasing device for biasing at least a portion of the nozzle assembly toward the endface such that when contact occurs between the nozzle assembly and the endface, a biasing force of the portion of the nozzle assembly is overcome and the portion of the nozzle assembly moves relative to the cleaning apparatus.
