Embodiment Construction

[0026] Below in conjunction with specific embodiment the present invention is described in further detail

[0027] The invention provides a single-channel optical fiber rotary connector with long space life. The rotator uses two self-focusing lenses with ceramic sleeves for centering coupling, so that the coupling efficiency is high and the insertion loss is low. At the same time, in order to avoid the problem that the optical axis does not coincide with the structural axis during the rotation of the self-focusing lens, the space long-life single-channel optical fiber rotary connector of the present invention introduces a fine-tuning mechanism. The fine-tuning mechanism makes the allowable radial error smaller than that of the existing rotator. Large, which greatly reduces the difficulty of assembly, and also reduces the insertion loss and loss rotation variation.

[0028] Such as figure 1 with figure 2 As shown, the space long-life single-channel optical fiber rotary conne...

Abstract

The invention provides a space long-service-life single-channel optical fiber rotary connector. The problems that an existing optical fiber rotary connector is large in loss, low in coupling efficiency and complex in structure are solved. In the space long-service-life single-channel optical fiber rotary connector, a shell is of a sleeve structure, and a rotor ceramic sleeve is arranged on the left side of the interior of a through hole of the shell through a bearing assembly; a first optical collimation device is installed in the rotor ceramic sleeve, and a rotor optical fiber is arranged onthe left side of the first optical collimation device and coaxially connected with the first optical collimation device. The stator ceramic sleeve is arranged on the right side of the interior of thethrough hole of the shell, and the radial position is adjusted through a fine adjustment assembly arranged on the shell; a second optical collimation device is installed in the stator ceramic sleeve,and the optical axis of the second optical collimation device is coaxial with the optical axis of the first optical collimation device. And the stator optical fiber is arranged on the right side of the second optical collimation device and is coaxially connected with the second optical collimation device.

Description

technical field [0001] The invention belongs to the field of optical fiber communication, especially relates to the field of long-time space transmission of large-capacity and high-speed signals, and specifically relates to a space long-life single-channel optical fiber rotary connector, which is mainly used in the rotary coupling transmission of optical signals between relative rotating devices in space. occasion. Background technique [0002] Optical fiber rotary connector is a device that uses optical fiber as the transmission medium to transmit signals from a rotating platform to a stationary platform. Optical fiber rotary connectors are widely used in civil and military fields. Civilian fields are mostly used in medical equipment, industrial control, energy development, etc. Military fields are mostly used in radars, tanks and other rotating platforms that need to continuously scan and receive radar signals and transmit them to In the field of communication, microwave ...
