Embodiment Construction

[0027] A tapered refraction multi-channel optical fiber rotary connector of the present invention will be described in detail below with reference to the embodiments and drawings.

[0028] A tapered refraction multi-channel optical fiber rotary connector of the present invention includes multiple communication channels, and the form of rotating optical signal transmission can be described as signal transmission between a spatial ring transmitter and another stationary receiver. This process is similar to the propagation process of ring light in the conical refraction inverse effect in biaxial crystals. The input ends of multiple channels form the rotor, and the biaxial crystal, coupling lens, output end and wavelength division multiplexing form the stator. Let each input channel transmit signals of different wavelengths, and the ring light is generated during the rotation process. According to the reverse process of the conical refraction effect in the biaxial crystal, the inc...

Abstract

A multichannel optical fiber rotary connector achieving conical refraction comprises a rotor and a demultiplexing system. The rotor is arranged in a stator sleeve through a bearing. The demultiplexing system is composed of a demultiplexer sleeve connected with the output end of the stator sleeve, a demultiplexer arranged in the demultiplexer sleeve, and an output collimator arranged at the output end of the demultiplexer sleeve. The output end of the rotor is provided with two to twenty input optical fiber collimators. A biaxial crystal is arranged in the stator sleeve and corresponds to the light output end of each input optical fiber collimator. A convergent lens or a lens set is embedded in an output end cover of the stator sleeve and corresponds to the light output end of the biaxial crystal. A collimator fixing sleeve is embedded and corresponds to the light output side of the convergent lens or the lens set. A collimator or large-core-diameter optical fiber is fixedly arranged in the center of the collimator fixing sleeve in the axial direction. The rear end of the collimator or the rear end of the large-core-diameter optical fiber is connected with the demultiplexer in the demultiplexing system. The multichannel optical fiber rotary connector achieving conical refraction has the advantages of being simple in structure, resistant to electromagnetic interference, small in insertion loss, high in assembly accuracy, and stable and reliable in performance.
