A Parallel Optical Fiber Transceiver Module

Abstract

This invention discloses a parallel optical fiber transceiver module, comprising a laser array, a photodetector array, a driving circuit board and a two-dimensional optical fiber array; the laser array and the photodetector array are mounted in two rows on the driving circuit board, and aligned and coupled with two rows of optical fibers in the fiber array respectively, and glue is used for fixing; the two-dimensional optical fiber array is fabricated on a positioning substrate with both sides etched; the invention has the following beneficial effects: through the double-sided exposure technology in the microelectronic process, a mask pattern is made on both sides of a piece of quartz glass, and then a high-precision optical fiber positioning slot array is etched through the chemical etching process. The double-exposure photoetching machine in the microelectronic process can ensure that the mask pattern on the same side has a high positioning accuracy, thus meeting the technical requirements of the parallel optical fiber transceiver module.
