Technical Field

Background

With the development of communication technology, optical fiber transmission is increasingly applied to communication systems, and optical fibers are mainly connected with optical fibers through optical fiber connectors and optical fiber adapters. An Optical fiber connector is a plug-in connector based on a single-core plug and an adapter, and is usually a main part of a mechanical connector in an Optical Distribution Network (ODN).

During ODN engineering field implementation and subsequent maintenance, it is often necessary to fabricate fiber pigtails in the field. There are two methods generally used at present: one is field fusion, that is, a fusion splicer is used to fuse a section of optical fiber prefabricated into an end in a factory with an optical cable; the other is field assembly, i.e. assembling a mechanical fiber optic connector directly on the cable. The field welding needs welding machines and other equipment, and has certain requirements on the operating environment; the field assembly has certain requirements on the quality of operators and certain failure rate. The human factor is often the greatest in the case of field assembly failure. For field assembly, the following problems often arise:

1) the use of miller clamp to remove the coating of the optical fiber 250 is easy to damage the optical fiber;

2) the cutting lengths of the optical fibers are different among different types of cutting knives;

3) the field assembly type quick connector needs to manually align the optical fiber, and the optical fiber is easy to touch the inner wall of the connector during alignment, so that the pollution of a cut end face is caused;

4) it is difficult for an operator in a low light environment or older to perform an optical fiber alignment operation;

5) after the optical fiber is penetrated into the field assembly type quick connector, the bending degree of the optical fiber needs to be manually controlled;

6) after the optical fiber is penetrated, an effective fixing structure is not provided, and the optical fiber butt joint points are easy to separate when subsequent operation is carried out;
