Problems solved by technology
[0004] However, the 12-core MPO ferrule has a long arrangement distance along the ferrule width direction
After injection molding, the material shrinks, and the ferrule presents a microscopic bending state. The closer to the edge of the fiber hole, the greater the deviation from the central coordinate axis, resulting in large insertion loss.

The embodiment of the invention provides an optical fiber stub and a multi-core optical fiber connector. The optical fiber stub comprises a stub body, wherein the stub body comprises a first front surface and a first rear surface; the first front surface and the first rear surface are positioned on two ends of the length direction L of an MT stub; the length of the first front surface in the widthdirection of the stub is 4.3-4.7mm; at least one group of optical fiber importing units is inserted from the first front surface of the stub body and penetrates through at least parts of the stub body; at least one group of optical fiber importing units comprises a first group of optical fiber importing units, wherein each optical fiber importing unit comprises at least five optical fiber holes;at least five optical fiber holes are arranged along the width direction of the first surface; and in addition, a gap is formed in the width direction of the first front surface between the two adjacent optical fiber holes in the first group of optical fiber importing units. The stub provided by the invention can improve an amount of optical fibers which can be inserted under a situation that thestub can be connected with other components of a standard MTRJ shell and an MTRJ multi-core connector.
Description
technical field [0001] The application relates to the field of optical communication, in particular to an optical fiber ferrule and a multi-core connector. Background technique [0002] ODN (Optical Distribution Network, Optical Distribution Network) is an FTTH (Fiber to the Home, Fiber to the Home) optical cable network based on PON (passive optical network, passive optical network) equipment. An optical transmission channel is provided between a terminal (optical line terminal, OLT) and a user end (for example, an optical network terminal, (optical network terminal, ONT)). In FTTH network construction, multi-core optical cables are usually used in the distribution section. Therefore, the miniaturized multi-core connector technology for indoor / outdoor use came into being. [0003] In the existing multi-core connector, the core core to be connected with the multi-core connector is the ferrule. The width of the standard MTRJ ferrule is 4.5mm, the distance between the guide...
