Problems solved by technology

However, no matter what kind of optical switch, it is necessary to use optical components that require precise alignment, so it is even more necessary to use complex precision structures and high-precision processing techniques to ensure the correctness of light refraction of optical components; and because optical components High-precision processing and technology, so the cost is relatively high

Embodiment Construction

[0018] The present invention utilizes the repetitive arrangement of existing optical fiber connectors with proficient manufacturing technology and low power loss, and completes the switching of different optical fiber paths through the movement mode of the mechanism. The optical switching device of the present invention can be widely used in optical fiber communication, such as in an optical time domain reflector (OTDR), to detect the loss of the optical fiber transmission path, as a monitoring of optical transmission; or as a Uses for Fiber Transport protection or backup, etc.

[0019] In the optical switching device of the present invention, the mobile carrier used can be designed in different types according to actual needs and space, such as a rotatable rotating disk or a movable carrier that can move linearly or horizontally. Here, the technical features of the present invention will be described in detail by taking the rotating disk as an example.

Abstract

The invention discloses a light switching apparatus, wherein a mobile support plate is provided two or more optical fiber connecting seats thereon, and each optical fiber connecting seat is respectively connected with an optical fiber path; and the mobile support plate is driven to move or to rotate by a driving device, to enable the optical fiber connecting seats on the mobile support plate to be switched to a corresponding position of an optical fiber connector and to enable the optical fiber connector to be fixed on one corresponding optical fiber connecting seat. The switches for different optical fiber paths can be achieved through a pure-mechanism type motion mode, and the apparatus is in no need of any optical element and has the advantages of simple structure, low cost, low signal loss, etc.

Description

technical field [0001] The present invention relates to an optical switcher used in optical fiber communication, in particular to a purely mechanical optical switcher without using optical components. Background technique [0002] Optical fiber (optical fiber) has the advantages of high bandwidth, large communication volume, small attenuation, long transmission distance, small signal crosstalk, high transmission quality, anti-electromagnetic interference, high confidentiality, and small size. Therefore, the use of light and Optical fiber communication, which transmits information through optical fiber, gradually replaces the traditional transmission method of using copper cables to transmit electrical signals. [0003] Optical fiber communication system has now become the most important way of wired communication. Optical fiber communication systems usually include a transmitter, which converts electrical signals into optical signals, and then transmits optical signals thro...
