摘要： The present disclosure provides a rollable optical fibre ribbon (100) with intermittent bonding. The rollable optical fibre ribbon (100) includes a plurality of optical fibres. The plurality of optical fibres (102) are placed parallel to each other, wherein the plurality of optical fibres (102) adjacent to each other are bonded intermittently along a length by a plurality of bonded portions (104). The plurality of bonded portions (104) occupies 3 to 20% of an area of the rollable optical fibre ribbon of length 1 meter. An area of the plurality of bonded portions (104) is defined as an area projected by the plurality of bonded (104) portions on a plane passing through centres of the plurality of optical fibres (102) of the rollable optical fibre ribbon (100) and extending longitudinally.

摘要： Methods of assembling polarization-maintaining (PM) optical fiber assemblies includes inserting optical fibers through channels of a receptacle with ends of extending past a front face of the receptacle. The first ends are radiated causing the initial fiber diameter to expand and results in an enlarged fiber diameter and forms an enlarged portion for a desired length along the PM optical fibers. The birefringent elements of the optical fibers are aligned to present a desired orientation and the optical fibers are further retracted until the enlarged portions abut the corresponding channels to mechanically lock the orientation of the optical fibers. The optical fiber assembly is further finished to maintain the polarity from the first end to a second end.
