[0001] The utility model relates to the technical field of optical fiber communication, in particular to a 36-core MPO jumper. Background Art

[0002] With the rapid development of domestic communications in recent years, optical cables, as a fundamental resource supporting communications, have also been deployed on a large scale. Fiber optic patch cables are primarily used to connect devices to fiber optic cabling links. These cables, with their thick protective layer, are typically used to connect optical terminals and terminal boxes. They are used in a variety of fields, including fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks.

[0003] Currently, the mainstream MPO patch cords in the industry are 8-core, 12-core, and 24-core. However, with the increasing demand for high density, the mainstream MPO patch cords have fewer core groups, which affects the stability of optical fiber connections. Moreover, when using common MPO patch cords, the branching cables are directly placed inside the box. The box is large and the cables are messy, which takes up a lot of space when in use and is not easy to quickly inspect and maintain.

[0004] There is an urgent need for a 36-core MPO patch cord to solve the technical defects raised in the above-mentioned technology. Utility Model Content

[0005] The purpose of the present invention is to provide a 36-core MPO jumper to solve the problem of poor stability of high-density optical fiber connections proposed in the above background technology.

[0008] Preferably, two sets of protective plates are fixedly connected to the front and rear ends of the right side of the protective box, and the branching connector is arranged between the protective plates.

[0009] Preferably, the branch cable can be embedded in the interior of the cable groove, the front end of the cable plate is fixedly connected with a rope buckle, and the top end of the cable plate is provided with a limiting rope.

[0010] Preferably, the limiting rope can be pressed on the distribution cable, and the top and bottom ends of the limiting rope are embedded in the rope buckle.

[0011] Preferably, the protective sleeve is slidably connected to the outside of the main line connector, and an anti-slip strip is fixedly connected to the outside of the protective sleeve.

[0012] Preferably, a positioning buckle is provided on the dust cover, and the dust cover can be put on the outside of the main line connector and the protective cover, and an indicator arrow is provided on the protective cover.

The 36-core MPO ferrules adopt Class C polarity, which effectively reduces the crosstalk problem in the wiring process and improves the integrity and accuracy of signal transmission;

[0016] (2) By providing a protective box, a cable tray, a limit rope, a protective plate, a cable trough and a rope buckle, the branch cables can be installed inside the protective box for use. The protective box has a small and compact structure, which greatly saves the use space.
