Technical field
The present invention relates to a kind of optica signal receivingl transmitting apparatus, particularly a kind of beam split type (lightsplitting type) bidirectional transmitting/receiving device.
Background technology
As depicted in figs. 1 and 2, known bidirectional optical signal receiving and transmitting device 1 mainly is with optical transmitting set 11 and optical receiver 12, is incorporated in the T shape housing 10.One end of housing 10 combines with optical fiber 13, and 12 of optical transmitting set 11 and optical receivers are arranged at all the other two ends of housing 10 respectively.Be respectively equipped with condenser lens 15,16 on the light emission of optical transmitting set 11 and optical receiver 12 and the optical receiving surface.In addition, spectroscope (light splitting filter) 14 is installed in the plotted point place of two beam paths (beam path) between optical transmitting set 11, optical receiver 12 and the optical fiber 13, and becomes miter angle with described two beam paths.Spectroscope 14 is coated with reflective coating (reflecting coating) in the face of the one side of optical receiver 12 and optical fiber 13, making can be through the reflection of the reflective coating of spectroscope 14 from the light beam of optical fiber 13 and reflex to optical receiver 12 downwards, from the light beam of the optical transmitting set 11 described spectroscope 14 of transmissive then, and directly inject optical fiber 13.
Known spectroscope is installed in the housing, with between optical transmitting set, optical receiver and optical fiber three, produces the optics running relation of optical signal transceiver transmission path allocation process, have different assembling morphologies, for example U.S.'s patent of invention the 6th, 075,635,5,841,562,5,838,859,5,408,559,5,347,605,5,127, No. 075 etc., the main exposure directly is packed in above-mentioned spectroscope 14 on the holder of enclosure interior formation or setting.
The disclosed bidirectional optical signal receiving and transmitting device of above-mentioned each patent, its spectroscope is a stand-alone assembly, must just can be fixed in the housing by special location and canned program, so its manufacturing process is comparatively complicated and accurate, and then makes manufacturing cost higher, moreover, also because spectroscope needs so accurate complicated procedure, and make the volume of housing be difficult to dwindle, because of the housing volume is littler, then more be unfavorable for the processing of spectroscopical location.
Summary of the invention
Main purpose of the present invention is to solve the above-mentioned defective that exists in the prior art, the present invention is with simple framework, adopt the optical transmitting set of transistor outline package (TO-can) structure, and the capping of spectroscope and optical transmitting set is combined as a whole, make spectroscope become the part of optical transmitting set, spectroscope promptly need not extra location structure and procedure, and therefore makes that the volume of housing is dwindled, and no longer is subjected to the restriction of spectroscope location structure.

Embodiment
Relevant technology contents of the present invention and detailed description, existing conjunction with figs. is described as follows:
Fig. 3 is an assembled sectional view of the present invention.As shown in Figure 3, bidirectional optical signal receiving and transmitting device 2 of the present invention mainly comprises T shape housing 21, optical transmitting set 22 and optical receiver 23.Ends in two of housing 21 straight-through ends are coupled on the optical fiber 3 by sleeve pipe 24, and 22 of optical transmitting sets are fixedly arranged on another straight-through end of housing 21, and the beam path that makes its emitted light beams path and optical fiber 3 in line; Optical receiver 23 is fixedly arranged on the 3rd end of housing 21, makes the beam path of optical receiver 23 vertical with beam path between optical fiber 3 and the optical transmitting set 22.
Described optical transmitting set 22 comprises pedestal 220 and is located at luminescence component 224 on the pedestal 220 that luminescence component 224 for example is light-emitting diode (LED) or laser diode (LD).Luminescence component 224 belows are provided with inspection optical assembly 226, by cup-shaped capping 221 luminescence component 224 and inspection optical assembly 226 are sealed in the pedestal 220, and luminescence component 224 and inspection optical assembly 226 cover be overlying in the capping 221, thereby form a transistor outline package (Transistor Outline can, TO-can).The bottom surface 225 of capping 221 becomes miter angle to tilt with beam path between optical transmitting set 22 and the optical fiber 3, the middle body of bottom surface 225 is the saturating window of hollow, on described window, be installed with spectroscope 222, described spectroscope 222 is coated with reflective coating (reflecting coating) 227 towards the side of optical receiver 23, light beam from optical fiber 3 is reflected with right-angle steering, and directive optical receiver 23, spectroscope 222 also is provided with plated film 228 towards the side of optical transmitting set 22, allowing can be according to the transmission ratio of plated film 228 settings from the light beam of optical transmitting set 22, the directly described spectroscope 222 of transmission and directive optical fiber, and there is segment beam to be reflected, receive reflected beams by inspection optical assembly 226, whether normally transmit to detect described laser.Described spectroscope 222 preferably is provided with condenser lens 223 towards the side of luminescence component 224, so that the light beam that luminescence component 224 is sent can be more concentrated, is also detected to examining optical assembly 226 by plated film 228 reflecting part light beams at condenser lens 223 in addition.
Above-mentioned optical receiver 23 also can be preferably the TO-can framework, and its light receiving surface also can preferably be provided with condenser lens 231.
Fig. 4 is that light R-T unit of the present invention is in the schematic diagram that the two-way biography of light signal is received state.As shown in Figure 4, after optica signal receivingl transmitting apparatus of the present invention was made up of said modules, the light signal that optical transmitting set 22 is launched will be via the spectroscope 222 and plated film 228 transmissions thereof of capping 221, and were incident to the optical fiber 3 of same axial arrangement and transmit to the outside.The light signal that optical fiber 3 transmits to light R-T unit 2 will be reflected with the right angle by the reflective coating 227 of spectroscope 222, is received and be incident to optical receiver 23.
Because said structure utilizes the TO-can framework, the capping 221 and the spectroscope 222 of optical transmitting set 22 are combined as a whole, substituted known independent spectroscope, thereby shortened the distance between known spectroscope and optical transmitting set, optical receiver, the optical fiber, can make that not only the overall volume of housing is effectively dwindled, more can simplify production procedure and cost, and make the bidirectional light receiving and transmitting Design of device have more elasticity.
Above-mentioned is the preferred embodiments of the present invention only, is not to be used for limiting practical range of the present invention.All equalizations of being done in claim of the present invention change and modify, and all should be included in the claim of the present invention.
