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.

An optical transceiver includes a substrate, a housing, a ferrule and a fixture. The housing is disposed on an outer surface of the substrate and includes a pressed portion and an inset portion connected to each other. The pressed portion defines a first pressed surface, and the ferrule is disposed on the inset portion. The fixture is disposed on the housing, a first pressing surface of the fixture is pressed against the first pressed surface of the housing, and a second pressing surface of the fixture is pressed against a second pressed surface of the ferrule. The fixture detached from the housing is in a force-free condition, and a distance between the first pressing surface and the second pressing surface in the force-free condition is smaller than a distance between the first pressed surface and the second pressed surface.
