MPO high-density optical fiber pre-connection systems are currently mainly used in three major areas: applications in high-density environments in data centers, applications of optical fibers to buildings, and applications for connection within optical transceivers such as optical splitters, 40G, 100G, QSFP +. The MPO connector is a multi-core number connector standard, and is generally formed by arranging 12-core optical fibers into a column, and supporting one or more columns of optical fibers in the same MPO connector, wherein the standard is specified by IEC61754-7, and the optical fibers are divided into one column (12 cores) and multiple columns (24 cores or more) according to the number of the cores arranged in the connector. MPO connector types are distinguished by several factors specified according to IEC 61754-7: core Number (fiber Array Number), Male-Female head (Male-Female), polarity (Key), polish type (PC or APC).

The prior MPO optical fiber connector has the following defects:

in the MPO optical fiber connector, a guide PIN (PIN) is made of stainless steel, the guide PIN can improve the butt joint precision of two connectors and is limited to the processing precision of metal PINs, and a product using the metal PIN has poor plugging repeatability data and poor repeatability indexes;

2. although the metal PIN is elliptical on the two end faces, when the PIN needle is inserted into the centering hole of the MPO ferrule, the metal PIN still has a cutting effect on materials in the PIN hole, and after the metal PIN is inserted and pulled for many times, the inner hole of the PIN becomes irregular, so that the performance of the MPO ferrule is poor when a repeatability test is performed;

3. the metal PIN needle, the external diameter is only 0.6mm less, and length is great, leads to PIN needle crooked easily in use to lead to the product disability rate great.

To this end, we have developed a multi-core multi-channel plug-in connector to solve the above disadvantages.
