Novel single-fiber bidirectional photoelectric conversion device without insertion core and integrated base thereof

Abstract

The embodiment of the invention discloses a novel single-fiber bidirectional photoelectric conversion device without an insertion core. The single-fiber bidirectional photoelectric conversion device comprises a laser, a detector, a die base, an optical filter, a ceramic sleeve and an integrated base. An insertion core adapter is integrated into the integrated base, and compared with traditional single-fiber bidirectional photoelectric conversion devices, the novel single-fiber bidirectional photoelectric conversion device has the advantages that the technical process, material cost and labor hour cost of separately manufacturing the insertion core adapter are reduced. Moreover, a laser lap joint mode of the insertion core adapter and the base is changed into an integrated molding mode, deformation, gaps and unstable factors easily generated at the laser welding part are avoided, and the stability and reliability are effectively improved. In addition, the outer end face of a laser connector has a predetermined inclination angle, and the problem can be solved that partial light emitted by the laser and/or light of an insertion core end of an optical fiber connector of an insertion device is directly emitted into the laser, so that the performance of the laser is deteriorated, and the optical transmission is affected; the device can be comparable to a device with the insertion core and meet data transmission requirements.

Description

technical field [0001] The invention relates to the technical field of optical fiber transmission, in particular to a novel ferrule-free single-fiber bidirectional photoelectric conversion device and an integrated base thereof. Background technique [0002] Single-fiber bidirectional optical conversion devices, or self-generating and self-receiving photoelectric conversion devices are the core components in modern optical fiber data transmission. Different from the ordinary dual-fiber transmission method, the single-fiber bidirectional technology completes the two-way transmission of signals on one optical fiber through the difference of the transmission wavelength. [0003] Therefore, the single-fiber bidirectional optical conversion device needs to complete two processes of converting optical signals into electrical signals and converting electrical signals into optical signals, and is usually used in optical fiber data transmission.
