Description

Technical Field

[0001] The invention relates to the technical field of communication network equipment, and in particular to a modular waterproof optical fiber coupling converter. Background Art

[0002] The demand for pre-termination of optical fiber resources is increasing. Pre-terminated optical interconnection products have been developed from indoor wiring applications to outdoor applications. Since optical interconnection products have always been mainly used indoors, the interface technology standards are also indoor interface standards. Therefore, in outdoor development, indoor standards are usually directly applied or a waterproof connector is added for use.

[0003] The existing connection methods between waterproof connectors and converters mostly adopt threaded connection or through the setting of slide groove 3031 and the limit column to cooperate with the screw card connection. Due to the limitation of the connection method, each converter can only be connected with one waterproof connector and they are not compatible. If the waterproof connector needs to be replaced, the converter that is compatible with it needs to be replaced together, which increases the cost. At the same time, since different customers have different demands for products, it is not only easy to order the wrong goods, but also brings trouble to subsequent installation and maintenance. Summary of the invention

[0004] In order to solve the problems of poor compatibility and troublesome installation and maintenance of converters, the present invention provides a modular waterproof fiber-optic coupling converter, which is compatible with most common waterproof connectors on the market and has high interchangeability.
