The fixed-center two-way optical signal transceiver device, the 1 split light fixes it in the housing, so the manufacturing flow sequence begins, and further, because the beam splitter needs such a precise complex processing program, the housing is The volume is difficult to shrink, because the shell 2: the smaller the 'the worse is not conducive to the positioning processing of the spectroscope. Heart-Private [Invention] The main purpose of ^^ is to solve the traditional lack of Shangyu and avoid the lack of children. The invention uses a simple architecture, uses T0_can thieves, and combines the beam splitter with the cover of the light emitter. = Become part of the light emitter, split # + Knife first mirror splitting light = the volume of the shell is reduced, no longer limited by the configuration of the knife mirror. [Embodiment] The technical content and detailed description of the present invention will now be described in conjunction with the drawings. Referring to the third embodiment, it is a sectional view of the combination of the present invention. The two-way optical transceiver unit 2 of the present invention mainly comprises a τ-shaped housing Γ, a light emitting unit 1122 and a light receiver 23, and one of the straight ends of the housing 21 is provided by the sleeve 24 The optical fiber 3:22 is fixed on the other through-end of the shell (4), so that the second: the path t is in line with the beam path of the optical fiber 3; the optical receiver (5) is 1310846 ft η fixed to the shell At the third end of the body 21, the beam path of the optical receiver 23 is made perpendicular to the beam path between the optical fiber 3 and the optical emitter 22. The light emitter 22 includes a base 220 and a light-emitting element 224 ' such as a light-emitting diode (LH) or a laser diode (LD) disposed on the base 220, and the light-emitting element 224 is disposed below the light-emitting element 224 A light detecting element 226 is sealed by the cup-shaped sealing member 221 to the susceptor 220, and the light-emitting element 224 and the light-detecting element 226 are covered therein to form a transistor-shaped outer casing (Transist〇r Outline can, TO- Can). The bottom surface 225 of the cover 221 is inclined at an angle of 45 degrees with the beam path between the light emitter 22 and the optical fiber 3. The central portion of the cover 221 is a hollow transparent window, and a beam splitter 222 is fixed on the transparent window. A side surface of the beam splitter 222 facing the light receiver 23 is plated with a ref lecting coating 227 ′ to cause the light beam from the optical fiber 3 to be deflected at a right angle to the light receiver 23, and the surface of the beam splitter 222 One side of the light emitter 22 is also provided with a coating film 228, so that the light beam from the light emitter can be directly transmitted through the beam splitter to the optical fiber according to the transmission ratio of the coating film 228 5 , and a part of the light beam is reflected by The photodetector #咖才妾 is detected to detect whether the laser light is normally transmitted. The focusing mirror 222 is preferably disposed with a focusing lens 223 facing the side of the light emitting element 224 so that the light beam emitted by the light emitting element can be more concentrated. The light beam is also concentrated by the focusing lens 223 and the partial light beam is reflected by the plating pan 228 to the light detecting element 2邡 Detection. For example, the light receiving (4) may preferably be a tq tuning structure, and the optical connection may preferably be provided with a focusing lens 231. = The paste is shown in the fourth figure, which is a schematic diagram of the optical transceiver of the present invention in the state of transmission. As shown in the figure, after the optical signal transmission and reception 7 1310846 of the present invention is set according to the components of the above components, the optical signal emitted by the optical transmitter 22 is transmitted through the beam splitter 222 of the cover 221 and the plating film 228 thereof, and is incident to The optical fiber 3 of the same axial configuration is transmitted to the outside, and the optical signal transmitted from the optical fiber 3 to the optical transceiver 2 is reflected by the reflective film layer 227 of the beam splitter 222 at a right angle, and is incident on the optical receiver for reception. Since the above structure is integrated with the beam splitter 222 by the cover 221 of the T0_can architecture light emitter 22, instead of the conventional independent beam splitter, it is known that the short splitter is separated from the light emitter, the light receiver, and the optical fiber. The distance can not only effectively reduce the overall volume of the housing, but also reduce the production process and cost, and make the design of the bidirectional optical transceiver more flexible. The above are only the preferred embodiments of the present invention and are not intended to limit the scope of the present invention. That is, the equivalent changes and modifications made by the scope of the patent application of the present invention are covered by the scope of the invention.
