Problems solved by technology

Its problem is that the optical structure coupling accuracy and the mechanical structure processing accuracy are strictly required.
The problem it brings is that the optical signal and the electrical signal are converted twice in the rotator, which brings a lot of noise signals
Because the rotator contains photoelectric conversion circuit, light emission circuit, detection circuit, electro-optic conversion circuit and corresponding auxiliary circuits, the volume of the rotator increases, which increases the production cost.

Abstract

The photoelectronic mixed fiber rotating connector consists of a fixed head at one end and a rotary head at the other end. The fixed head includes a flange and a frame and in the frame there are self-focusing lens or collimator lens, fiber connector and input fiber. The rotary head is a support assembly in an outer sleeve connected to the fixed flange and rotated by the support, and on the rotarysupport assembly there is a light receiver comprising lens, detector, DC bias circuit, impedance matching circuit and amplifier and a light emitter comprising amplifier, impedance matching circuit, DC bias circuit and light isolator; or there is a light transceiver module. The fiber rotating connector has simple inner structure, and is easy to realize light coupling with no signal distortion and high S / N ratio.

Description

technical field [0001] The invention provides a photoelectric hybrid optical fiber rotary connector, which belongs to the category of optical fiber rotary connectors. Background technique [0002] Optical fiber has the characteristics of wide bandwidth, anti-interference, low loss, light weight, and small size, making it an ideal signal carrier in more and more application fields. In the type of optical fiber transmission, in some cases, the transmission of optical signals often requires a rotary coupling connection in an intermediate link of the line, such as between the radar antenna and its on-board signal processing system, between the submarine robot and the control ship, The connection lines between the manipulator and the main console used in industry are required to be provided with a freely rotating connection device. The device must strictly guarantee the corresponding relationship between channels and communication between channels. [...
