Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following.

As shown in fig. 1, the 45-degree optical fiber array comprises a substrate 1, optical fibers 2 and a cover plate 3; the utility model discloses a novel optical fiber ribbon, including base plate 1, apron 3, apron 1, apron 3, base plate 1 upper surface are provided with a plurality of V-arrangement grooves, the V-arrangement inslot is provided with gets rid of optic fibre 2 after the cladding, 2 tops of optic fibre can bend 30 degrees to 50 degrees and not split, the optic fibre in the V-arrangement inslot need be arranged according to the rule optical fiber ribbon colour on the base 1, apron 3 and base plate 1's laminating part size matches completely, apron 3 is placed on base plate 1, 1 upper surface of base plate is provided with.

preferably, the bare fiber is a single-mode bending insensitive fiber, the dimensional tolerance is plus or minus 0.2mm, the insertion loss of 4 channels is less than or equal to 0.8db according to the feeding inspection standard, the front surface and the back surface of the extended tip of the fiber array are kept clean and intact, the black points of the 45-degree end surfaces of the 4 channels of the fiber array are required to be on the same central line, and the inclination angle of the central line relative to the B-groove edge of the fiber array is plus or minus 0.5 degrees.

the V-shaped grooves are parallel to each other and are equally spaced. Preferably, the adjacent spacing of the V-shaped grooves is 250 um.

The substrate 1 is provided with an integrally formed step, and a plurality of holes are processed on the side surface of the step and used for the penetration of optical fibers.

Preferably, each base plate is provided with 4 slots.

The side of 1 trompil of base plate becomes 45 degrees angles with the horizontal plane, the slotted side of base plate 1 and apron 3 becomes 45 degrees angles with the horizontal plane.

The working process of the invention is as follows:

The operating personnel check the raw material V groove, the cover plate and the belt fiber, and check whether the sizes of the V groove and the cover plate are matched. The optical fiber is wiped by using dust-free cloth, so that the surface of the optical fiber is free from impurities and damage, and whether the optical fiber is reversely wound, peeled and unclean or not and whether the length of the wire is standard size or not are checked.

Arranging the cleaned optical fiber ribbons in sequence, performing elastic fiber test on the optical fibers, bending the top ends of the optical fibers downwards by 30-50 degrees by using a forefinger, and performing the next operation if the optical fibers are not broken; if the optical fiber is broken, returning to the previous procedure to prepare the material again.

the optical fiber ribbons of different specifications and models have different colors, and the optical fiber arrangement sequence is as follows: the V-groove is in front, black is the first channel from the left hand, and blue is the last channel.

And placing the V-shaped groove, the belt fiber and the cover plate on an assembly fixture, fixing the belt fiber by masking paper, and fixing the V-shaped groove and the cover plate by pressing strips.

The fiber peeling position should be placed at the position 2/3 of the V-groove non-groove area, and the length and width of the cover plate and the V-groove are aligned without obvious dislocation.

A pressing plate is placed in the groove and kept in the middle of the V-shaped groove.

Observing with a microscope, adjusting the optical fiber into the V-shaped groove, aligning the cover plate, and adjusting the knob.

And opening the pressing strip under the observation of a microscope, and slightly shifting the optical fiber by using a dental floss pick to check whether the bare fiber in the V-shaped groove is loosened. And lifting the clamp to check fiber breakage. And laterally placing a clamp to check dislocation.

And (3) after the assembly operation is finished, inspection is required: the clamp has the advantages of no fiber breakage, no dislocation, no pollution, no damage, no reverse placement of a cover plate chamfer, no crack, no pressing plate, no alignment of a belt fiber and no removal of the clamp without a groove.
