摘要： The challenge of pulling an optical fiber having a connector at its terminal end without incurring damage to the fiber or connector due to excessive pulling or bending is met by introducing a breakaway feature that disconnects the connectorized fiber from the pulling mechanism upon detecting excessive force. The breakaway feature may be positioned at several locations along the pathway connecting the optical fiber and the pulling force. In one embodiment the breakaway feature is disposed on a cover over the connectorized front end of the optical fiber. In other embodiments the breakaway element is inserted along the cord connecting the connectorized optical fiber to the pulling force.

摘要： A pin retainer for a fiber optic connector includes a ferrule having a front face defining a hole for receiving a guide pin. The pin retainer permits the guide pin to be inserted in the field following assembly of the connector and polishing the front face of the ferrule. The pin retainer includes a frame and at least one retaining tab for engaging the guide pin when the guide pin is inserted into the hole from the front face. The frame may have an open side for permitting the pin retainer to be fabricated using a highly efficient wire EDM process. The pin retainer provides a pin retention force of at least about 8 lbs and may include a plurality of retaining tabs for engaging the guide pin in more than one location. The ferrule may be provided with an external feature to position the pin retainer on the ferrule.

摘要： Disclosed is a method and apparatus for quickly joining one set of optical fibers to another set followed by permanent repair. The basic apparatus comprises two frames, each having a cross member containing a plurality of spaced apart optical fiber connectors; optical fibers optically connecting one connector in one frame to a corresponding connector in the other frame; at least one means in each frame to anchor a cable to the frame; and a bracket means attached to each frame between that frame's connectors and anchor means. A bare fiber adapter is also disclosed adapted to removably receive an optical fiber coaxially. On one end of the bare fiber adapter is a means affixed thereto for removably securing an optical fiber within the adapter.The repair method of a severed fiber optic cable involves the use of the above described apparatus as follows:Cable ends to be joined are stripped and secured in each frame. Bare fiber adapters are then removably secured to the terminal portions of the optical fibers of both cable ends sought to be optically connected to one another. Thereafter, the bare fiber adapters of one cable end are connected to the connectors of one frame and a like procedure carried out with the bare fiber adapters of the other cable end and frame to restore optical communication. After first routing traffic over other fibers, bare fiber adapters of a given fiber are removed and the fibers optically joined together in a more permanent fashion. When there is not enough slack in the damaged cable to join the fibers directly, a piece of spare cable has to be stripped and adhered to the frames to carry out permanent joining. Subsequently, the bare fiber adapters of the corresponding fiber sought to be permanently connected are removed and the fibers are permanently joined to each other in a predetermined manner.

摘要： An optical fiber splitter has a higher density fiber optic array that allows for smaller packaging. The optical fibers that extend from the optical fiber splitter have one end connectorized and their spacing at the other end reduced, thereby eliminating components that were heretofore required. A method of making the fiber optic array includes interleaving the optical fibers to reduce the overall dimensions of the fiber optic array and the fiber optic splitter. A tool is used to reduce the spacing of the optical fibers in the fiber optic array.

摘要： The fiber optic interconnection enclosure, such as a fiber optic distribution frame or the like, effectively limits the entry of particles, such as dust and other contaminants, into the enclosure. For example, the fiber optic interconnection enclosure can maintain a greater pressure, i.e., a positive pressure, within the internal cavity defined by the enclosure than outside of the internal cavity so as to effectively limit the entry of particles into the internal cavity, even as the door of the fiber optic interconnection enclosure is repeatedly opened and closed. The fiber optic interconnection enclosure generally includes at least one fan to draw air into the internal cavity through an air inlet port defined by the cabinet and to circulate the air through the internal cavity in order to reduce the number of particles that settle upon or are transferred to the end faces of the optical fibers or other surfaces within the internal cavity. By filtering the air drawn into the internal cavity, at least some of the particles are removed from the air drawn into the internal cavity. In addition, by expelling at least some of the air that has circulated within the internal cavity through a vent, a number of the particles that may have been otherwise trapped within the internal cavity can also be expelled prior to settling upon the end face of an optical fiber or other surfaces within the internal cavity.
