Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connectors, in particular to a high return loss multi-core neutral optical fiber connector. Background Art

[0002] A fiber optic connector is a device that makes a detachable (movable) connection between optical fibers. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized. When the fiber cores are not precisely aligned, that is, when the centering positioning of the connector core deviates, the insertion loss and return loss will be greatly affected.

[0003] When the wire cores in current fiber optic connectors are docked with each other, the contact surfaces of the wire ends cannot be on the same axis to a large extent, so slight misalignment is prone to occur, resulting in poor transmission effects. In addition, most fiber optic connectors are equipped with plastic elastic arms at the plugs or sockets to fix the fiber optic connectors. However, in reality, the elastic arms are usually prone to breakage and aging during use, making it inconvenient to replace them later and poor in practicality. Utility Model Content
