摘要:
Apparatus for clamping optical fibres of a multi-fibre optic cable in a ribbon arrangement is disclosed. The apparatus includes a housing and a clamp assembly rotatably mounted within the housing. The clamp assembly includes a first clamp plate hingedly connected to a second clamp plate, so as to define a pair of jaws for receiving a plurality of optical fibres. As the clamp assembly is rotated from a first position to a second position, the first and second clamp plates are urged together, thereby at least partially closing the jaws so as to clamp the plurality of optical fibres therebetween, which in turn aligns the fibres within a plane to form the ribbon arrangement.

A method of analyzing a polarization-maintaining (PM) optical fiber includes illuminating a side of the PM optical fiber, physically rotating the PM optical fiber and measuring light intensity of light transmitted through the PM optical fiber to obtain an image profile, mathematically shifting the image profile at incremental rotation angles, expanding the image profile at each rotational angle into a Fourier series profile, and determining points of symmetry of the PM optical fiber based on the Fourier series profiles.

A method for aligning an optical fiber that includes: directing a laser beam into a beam splitter to generate a pair of beams that are directed to a pair of reflectors that redirect the pair of beams such that the pair of beams intersect with each other and go to a pair of power detectors; and moving an optical fiber into the paths of the pair of beams until power detected at each of the pair of detectors is minimized.

A fiber optic mechanical splicer includes: a fiber connection base including a plurality of insertion parts, fiber connection parts, and auxiliary protuberances, the insertion parts being formed at lengthwise opposite sides of the fiber connection base, each of the insertion parts having an insertion hole through which an optical cable is inserted, the fiber connection parts being formed between and integrally with the insertion parts, the fiber connection parts having a connection groove formed at a central portion of the fiber connection parts and extending in a lengthwise direction of the fiber connection parts and insertion grooves formed at opposite ends of the connection groove, each of the insertion grooves being narrower in a downward direction, each of the auxiliary protuberance protruding upward from edges of the fiber connection parts; a base cover assembled with the fiber connection base while covering the fiber connection parts, the base cover being supported by the auxiliary protuberances; and one or more fastening clamps elastically fitted around the fiber connection base and the base cover through sliding in a state in which the fastening clamps are opposed to each other, the fastening clamps fixedly holding the fiber connection base and the base cover with each other while pressing the optical fiber seated in the connection groove.

A fiber optic connector comprises a mechanical splice assembly, a cam for activating the mechanical splice assembly, a mechanical splice assembly holder for accommodating and retaining the rear portion of the mechanical splice assembly, a clamp holder, a connector housing for accommodating the front portion of the mechanical splice assembly and a shroud. A method for making the same fiber optic connector is also provided. The mechanical splice assembly can be mounted onto the splice assembly holder without using adhesives and the fiber optic connector can be activated/reactivated without using special tools in field installation.
摘要:
A method for laser processing arrays of optical fibers and high- fiber count splicing connectors and adapters are disclosed. The method includes the steps of providing a structure (30) having optical fibers arranged in a plurality of rows and placing a protection element (140,144) adjacent to a first row of optical fibers and a second row of optical fibers. Thereafter, the first row of optical fibers can be processed using the laser (48). The protection element may also be used to move optical fibers. In one embodiment, the protection element has a first portion (140) and a second portion (144) that have relative movement therebetween. In other variations, an absorption element may be provided adjacent the first row of optical fibers for inhibiting incidental damage to the structure.
