摘要： A dust cap is provided that includes a translucent end member that permits optical communication while the dust cap remains mounted upon a ferrule. The dust cap includes a sleeve having an open first end and an opposed second end that is closed by the translucent end member. The end member can also include a lens to facilitate optical communication. A medial portion of the sleeve can also define an internal chamfer that extends radially inward for engaging the ferrule such that the front face of the ferrule is spaced from the second end of the sleeve, thereby preventing contaminants from being transferred from the second end of the sleeve to the polished front face of the ferrule. The dust cap can also define a groove extending lengthwise through only a portion of the sleeve, i.e., from the first end of the sleeve to a medial portion of the sleeve. The groove therefore permits air to vent from the bore while the dust cap is being mounted upon the ferrule, while isolating the front face of the ferrule from the external environment once the dust cap has been fully mounted, thereby protecting the polished front face of the ferrule from contaminants that may enter the groove. A method is also provided for testing the continuity of an optical fiber jumper that utilizes optical communications conducted through the translucent dust caps.

摘要： A method of cleaving an optical fiber using a disposable abrasive film is disclosed. The method includes preparing an end of an optical fiber by exposing a length of the optical fiber. The exposed optical fiber is brought into contact with a tangential swipe formed of abrasive film to cause the optical fiber to cleave substantially at the location of contact leaving an optical fiber stub with a cleaved end. The optical fiber stub is polished with a polishing film having a coarse grit and may be polished a second time with a polishing film having a fine grit.

摘要： Connectorized nano-engineered optical fibers and method for forming them are disclosed. The methods include heating a mid-span bare fiber portion of the nano-engineered fiber to substantially collapse the airlines therein so as to form a substantially airline-free portion. The fiber is then inserted into a ferrule channel so that the fiber end protrudes beyond the ferrule end face, but with the substantially airline-free portion positioned at the ferrule end face. The fiber is then cleaved at or near the ferrule end face in the substantially airline-free portion, and the new fiber end face polished to create a solid fiber end face that coincides with the ferrule end face. The methods result in relatively small changes to the mode field diameter (MFD) and/or to the outer cladding diameter.

摘要： Systems and methods of collapsing the air lines in the air line-containing region of a nanostructure optical fiber are disclosed. One method includes initiating irradiation of a portion of the nanostructure optical fiber from essentially opposite directions with at least first and second laser beams having substantially equal power and essentially the same mid-infrared wavelength. The method includes continuing the irradiation for an irradiation time t1 so as to bring the optical fiber portion to a softening temperature TS at which the air lines in the optical fiber portion collapse into the adjacent cladding. Exemplary optical systems for carrying out the air- line-collapsing methods of the present invention are also disclosed.
