Abstract
A composition for cleaning the ferrule end surface of an optical fiber that has been installed in a connector, such as a connector coupler or bulkhead receptacle, is made from sintered polymeric particles and/or stranded fibers and is formed into a cleaning head (22a, 22b, 22c). The composition provides a matrix of open-celled multi-directional pores to lift, absorb, trap and remove contamination from the ferrule end faces (14a, 14b, 14c) and the end face of the optical fiber therein. The open-celled structure of the cleaning head (22a, 22b, 22c) allows the contact surface to compress both laterally and radially where it contacts the ferrule end, thus permitting effective cleaning for all ferrule end designs. The cleaning head may be used either dry or with a cleaning solvent.
Claims12
A cleaning device for cleaning an optical fiber, the device having a cleaning head comprising:
- a polymeric open-celled structure comprised of a coherent body of one or more thermally sintered polymers and having two ends, a first end and an opposite, second end, and at least three zones, the zones comprising a compression zone which terminates in a contact area at the first end of the cleaning head;
- a sidewall cleaning zone adjacent to the compression zone, wherein the compression zone has a polymer density which is less than the polymer density of the sidewall cleaning zone;
- and a base zone adjacent to the sidewall cleaning zone, wherein the base zone has a polymer density which is greater than the polymer density of the sidewall cleaning zone.
The cleaning device of claim 1 or claim 6 wherein the entirety of the contact area is comprised of a continuous uninterrupted surface.
A cleaning device for cleaning an optical fiber, the device having a cleaning head comprising:
- a polymeric open-celled structure comprised of a coherent body of one or more thermally sintered polymers and having two ends and three zones, the zones consisting essentially of a compression zone at one end, a sidewall cleaning zone adjacent to the compression zone, and a base zone adjacent to the sidewall cleaning zone and separated from the compression zone by the sidewall cleaning zone, wherein the polymer density of the compression zone is less than the polymer density of the sidewall cleaning zone, and the polymer density of the sidewall cleaning zone is less than the polymer density of the base zone.
