Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric hybrid cable connection, in particular to a photoelectric hybrid cable movable connector for communications. Background Art

[0002] Currently, my country's small and medium-sized enterprises (SMEs) are in urgent need of gigabit optical network deployment. Through active exploration by my country's basic telecommunications companies, FTTR-B has emerged as the most suitable solution for gigabit optical network deployment for these enterprises, owing to its high bandwidth, excellent coverage, intelligent operations and maintenance, easy deployment, and energy-saving features. The deployment of FTTR-B equipment has become a crucial milestone in the development of gigabit optical networks. Remote connections between master and slave devices require an appropriately long optical-to-electrical hybrid cable as the connecting medium. Optical-to-electrical hybrid cables transmit data, voice, video, and other signals over a single optical fiber, while also using a pair of electrical conductors to deliver power. This integrated data transmission and power supply ensures more convenient and reliable line connections, making them a key solution for fiber-to-the-end (FTT) deployments. This type of cabling is typically installed in suspended ceilings. If the optical-to-electrical hybrid cable is damaged by twisting or pulling during installation, or if the cable is insufficiently long, new cables must be re-laid, which is a significant engineering effort and wasteful.

[0003] The utility model with announcement number CN206975291U discloses a single-core optical fiber mechanical splicer suitable for use with dish-shaped drop cables. The splicer comprises a pigtail assembly and a glass microgroove. The pigtail assembly is provided with connecting components at both ends. The connecting components are U-shaped, and a locking component is provided at the top of one side of the connecting component. The locking component cooperates with the connecting component to close the top of the U-shape. During installation, the optical fiber is inserted into the pigtail assembly, and then the tightening component is snapped into place with the connecting component to complete the installation. However, the single-core optical fiber mechanical splicer is only used for splicing single-core optical fibers and cannot be used to splice optoelectronic hybrid cables. Utility Model Content
