Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

Referring to fig. 1 to 3, an MT ferrule according to an embodiment of the present invention includes a body 1, a first optical fiber channel 2, and a second optical fiber channel 3.

The body 1 has a butting portion 11 extending in a butting direction; the first optical fiber channel 2 penetrates through the butt joint part 11 along the butt joint direction, and the first optical fiber channel 2 is provided with four optical fiber holes 4; the second optical fiber channel 3 penetrates the butt joint part 11 along the butt joint direction, and the second optical fiber channel 3 is provided with four optical fiber holes 4. Wherein a closed spacer is formed between the first fiber channel 2 and the second fiber channel 3.

Compared with the existing twelve-hole MT ferrule, the MT ferrule seals the middle four optical fiber holes 4 through the arrangement of the spacer region to form the eight-hole MT ferrule so as to adapt to the use scene only needing the eight optical fiber holes 4.

In an exemplary embodiment, the first fiber channel 2, the second fiber channel 3, and the spacer are of equal width. The arrangement can reduce the manufacturing difficulty of the corresponding mould, and the existing twelve-hole MT core inserting mould is simply improved without redesigning the mould.

In an exemplary embodiment, the body 1 further includes a boss portion 12 formed at a trailing end of the abutment portion 11, the boss portion 12 having a thickness greater than a thickness of the abutment portion 11 to form a first stepped portion 13 at a junction of the abutment portion 11 and the boss portion 12. The first step portion 13 can play a limiting role when the MT inserting core is butted with other devices, and the MT inserting core is ensured to be butted in place.

Specifically, the body 1 is provided with a receiving groove 14, and the receiving groove 14 penetrates the boss portion 12 in the abutting direction and extends to the abutting portion 11. The optical fiber may be inserted into the optical fiber hole 4 along the receiving groove 14, and an adhesive may be filled in the receiving groove 14 to adhesively fix the optical fiber.

Further, a second step portion 5 is formed in the accommodating groove 14, a plurality of optical fiber grooves 51 extending in the butt joint direction are formed in the second step portion 5, and the optical fiber grooves 51 correspond to the optical fiber holes 4 one to one. The optical fiber groove 51 is in a semicircular arc shape and is arranged coaxially with the optical fiber hole 4, and the diameter of the optical fiber groove 51 is larger than that of the optical fiber hole 4. When the MT ferrule is inserted into the optical fiber, the protective layer at the end of the optical fiber needs to be peeled off, the bare fiber core is inserted into the optical fiber hole 4, and the optical fiber part wrapped with the protective layer can be supported and limited in the optical fiber groove 51.
