Abstract
The utility model relates to a single fiber bi-directional optical transceiver component, in particular to the optical transceiver component. The utility model provides the improved single fiber bi-directional optical transceiver component, which is provided with a laser, a laser tube body, a component seat, a detector, a splitter, a filter plate support, a core inserting sheath and a tail optical fiber component, wherein the filter plate is arranged in the detector, since the filter plate is arranged in the detector, the light which is used by the transmitting and the receiving has different wave lengths, and the bi-directional transmission of optical signals is realized through an optical fiber, thereby the light which enters the detector from outside passes through the filter plate by 100 %, and other light can not enter the detector, thereby the component fully prevents the light with other wavelengths from entering the tube, the light filtering effect is good, and the receiving sensitiveness of the detector is guaranteed. The component is convenient for installing the filter plate, the adhesive thereof is firmer and more reliable, the space of the inner thereof is saved, the requirements to the height of the detector are not high, the coupling and the adjustment of the detector are convenient and the cost of the detector is reduced.
Description
Technical field
The utility model relates to a kind of smooth transmitting-receiving subassembly, especially relates to a kind of single fiber bi-directional light transmitting-receiving subassembly.
Background technology
Light emission component (TOSA) and optical fiber receive module (ROSA) they are the important devices of optical fiber telecommunications system, and their effect is the conversion that realizes the light signal and the signal of telecommunication, and by realizing the transmission of light signal with the coupling of optical fiber.Existing light emission component and optical fiber receive module are the stand-alone assemblies of split.Though have light emission component and optical fiber receive module formed a kind of single fiber bi-directional light transmitting-receiving subassembly (BOSA), this single fiber bi-directional light transmitting-receiving subassembly is provided with laser, laser body, assembly seat, detector, light splitting piece, filter plate bearing, lock pin cover, pigtail assembly and filter plate, laser is located on the laser body, assembly seat is connected with the laser body, the filter plate bearing is connected with assembly seat, detector is located at a side of assembly seat, light splitting piece is located in the assembly seat, and pigtail assembly is connected with the filter plate bearing by pin bushing; But because light emission component and optical fiber receive module are combined into an assembly, light signal is by same Optical Fiber Transmission, and therefore the interference of light to receiving unit particularly launched in the easy phase mutual interference of light signal that transmits and receives.In order to address this problem, need outside optical fiber receive module, increase a filter plate, to filter unwanted light.
Because general single fiber bi-directional light transmitting-receiving subassembly manufacturer is not produce detector, the method that therefore solves the light interference is to install filter plate additional between detector and optical fiber.Can filter the light of coming in like this, but can't filter the light of coming in, so the reverberation of component internal is easy to enter detector, influence the receiving sensitivity of detector from the filter plate side from the filter plate front.Owing to be subjected to the restriction in component internal space, be applicable to the request detector long-focus of single fiber bi-directional light transmitting-receiving subassembly, highly little pipe cap in addition.
Summary of the invention
The purpose of this utility model is can't filter the light of coming in from the filter plate side at existing single fiber bi-directional light transmitting-receiving subassembly, the reverberation of component internal is easy to enter detector, influence the problems such as receiving sensitivity of detector, a kind of improved single fiber bi-directional light transmitting-receiving subassembly is provided.
The utility model is provided with laser, laser body, assembly seat, detector, light splitting piece, filter plate bearing, lock pin cover and pigtail assembly, is provided with filter plate in detector.
Filter plate preferably is located at detector pipe cap inboard, preferably establishes packing ring between filter plate and the detector pipe cap inboard.
Compare with the light emission component or the optical fiber receive module of split, the utility model uses single fiber bi-directional light transmitting-receiving subassembly can save an optical fiber.Compare with existing single fiber bi-directional light transmitting-receiving subassembly, the utility model is owing to be located at filter plate in the detector, transmit and receive the light that uses different wave length, realize the transmitted in both directions of light signal by an optical fiber, outside light 100% wave plate after filtration that enters detector like this, and other light can't enter detector, isolating exterior enters the light of other wavelength in the pipe fully, therefore filter effect is fine, has guaranteed the receiving sensitivity of detector.Because filter plate is located in the detector, be convenient to the installation of filter plate, it is bonding more firm and reliable, helps improving the reliability of assembly.In addition owing to saved the space of component internal, not very high to the requirement of detector height, therefore not only be convenient to the coupling and the adjustment of detector, and reduced the cost of detector.
