摘要： The present disclosure relates generally to methods for processing ferrules of fiber optic connectors such that the amount of polishing that is required is eliminated or at least reduced. In one example, an energy source is used to remove excess adhesive from the end face of the fiber and likely from an end face of the ferrule.

摘要： The present disclosure relates to a fiber optic component including a ferrule having a distal end and a proximal end. The ferrule defines a fiber passage extending though the ferrule along a fiber passage axis in a proximal-to-distal orientation. The fiber optic component also includes an optical fiber structure affixed within the fiber passage. The optical fiber structure includes a beam expansion section optically coupled to a sacrificial section. The beam expansion section has a construction adapted to expand an optical beam from a first beam diameter to an enlarged second beam diameter. The sacrificial section is configured to receive the optical beam having the second beam diameter from the beam expansion section. The sacrificial section is positioned at the distal end of the ferrule and has a polished end face at the distal end of the ferrule. The sacrificial section has a core-less construction or has a core with a core diameter that is larger than the enlarged second beam diameter.

摘要： A double flexible optical circuit includes: a flexible substrate supporting a plurality of optical fibers; a first connector terminating the optical fibers at a first end of the double flexible optical circuit; and a second connector terminating the optical fibers at a second end of the double flexible optical circuit. Each of the optical fibers is positioned in one of a plurality of separate extensions formed by the flexible substrate as the optical fibers extend from the first connector to the second connector. The first and second connectors are configured to be tested when the first and second connectors are connected through the double flexible optical circuit. The double flexible optical circuit is configured to be divided in half once the testing is complete to form two separate flexible optical circuits.

摘要： A support frame (10) for a cabling trunk assembly (1) is disclosed. In one embodiment, the support frame (10) has a main body (11) defining a mounting surface (41), and a first extension leg (50) extending along a first side edge (42) of the main body (11) and away from the mounting surface (41). Similarly, the support frame (10) can be provided with a second extension leg (52) that extends along a second side edge (44) of the main body (11) and away from the mounting surface (41). The extension legs (50, 52) may be provided with tabs (54, 56) to provide a secure connection with receiving grooves (28, 29) on a channel (12) of the cabling trunk assembly (1). The extension legs (50, 52) may also be configured to provide a snap-fit connection with the receiving grooves (28, 29).

摘要： The present disclosure generally relates to a method for processing optical fibers supported by a multi-fiber ferrule. The method can include laser cutting first and second rows of optical fibers in a first fiber cutting step by directing a laser beam in a first direction relative to the ferrule. The laser beam can cut the second row of optical fibers to a first fiber extension length and cut the first row of optical fibers to a second fiber extension length. The method can also include laser cutting the first row of optical fibers by directing a laser beam in a second direction relative to the multi-fiber ferrule. The laser beam cuts the first row of optical fibers to the first fiber extension length and by-passes the second row of optical fibers such that optical fibers of the second row of optical fibers remain at the first fiber extension length.

摘要： A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at non-conventional connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the non-conventional connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the non-conventional connectors adjacent the front of the body includes a ferrule, a ferrule hub supporting the ferrule, and a split sleeve surrounding the ferrule.

摘要： A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location, such as a multi-fiber connector, is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at one or more single or multi-fiber connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the connectors adjacent the front of the body includes a ferrule. Dark fibers can be provided if not all fiber locations are used in the multi-fiber connectors. Multiple flexible substrates can be used with one or more multi-fiber connectors.

摘要： A fiber optic cable and connector assembly is disclosed. In one aspect, the assembly includes a cable optical fiber, an optical fiber stub and a beam expanding fiber segment optically coupled between the cable optical fiber and the optical fiber stub. The optical fiber stub has a constant mode field diameter along its length and has a larger mode field diameter than the cable optical fiber. In another aspect, a fiber optic cable and connector assembly includes a fiber optic connector mounted at the end of a fiber optic cable. The fiber optic connector includes a ferrule assembly including an expanded beam fiber segment supported within the ferrule. The expanded beam fiber segment can be constructed such that the expanded beam fiber segment is polished first and then cleaved to an exact pitch length. The expanded beam fiber segment can be fusion spliced to a single mode optical fiber at a splice location behind the ferrule.
