The utility model has the advantages of simple and compact structure and reasonable, convenient assembling is swift, connect reliably, because optical emitter and optical receiver mutual independence on the space, scattered light that the transmission light that consequently can reduce light emitting devices formed owing to scattering or reflection and reverberation cause light receiving element crosstalks, assurance light receiving element's receiving performance.
Description
Technical field:
The utility model relates to communication technical field, particularly a kind of transceiver assembly.
Background technology:
Optical Cable Measurement is optical cable construction, safeguard, the important technical of repairing, adopting optical time domain reflectometer (OTDR) to carry out the field monitor of Fiber connection and junction loss, to measure evaluation be most effective method at present, this method is the backscattering that produces of Rayleigh scattering when utilizing light to transmit in a fiber and Fresnel reflection and the optoelectronic integration instrument of the precision made, be widely used in the maintenance construction of lightguide cable link, fiber lengths can be carried out, the transmission attenuation of optical fiber, the measurement of joint decay and fault location etc., but conventional OTDR equipment is usually expensive, and it is bulky, in order to reduce costs further, the competitiveness of lifting means, the OTDR equipment released both at home and abroad now, all trend towards the optical module structure making transceiver, be about to the transmitting that tradition is shared, receiver module is assembled in same shell, the composition integrated module of optical transceiver.
Utility model content:
In order to solve the problem, the utility model provides a kind of technical scheme: a kind of transceiver assembly, comprises housing; Its innovative point is: also comprise screw, optical cable fixed head, optical cable, heating panel, hold-down screw, lens, front isolator, light splitting piece, the polarizer, 45 degree of filters, rear isolator, optical fiber receive module, collimating lens, light emission component and two collimating lenses; Described optical cable is positioned on the left of housing, and described optical cable is fixed in the housing by optical cable fixed head and screw; Described heating panel is positioned at enclosure interior, and described heating panel is fixed on enclosure interior by hold-down screw, is from left to right provided with successively above described heating panel: lens, front isolator, light splitting piece, the polarizer, 45 degree of filters and rear isolator; Described optical fiber receive module is fixed on the right side of housing, is provided with collimating lens before described optical fiber receive module; Described light emission component is positioned at directly over 45 degree of filters, and described light emission component is fixed on housing upper face, is provided with two collimating lenses before described light emission component;
As preferably, described optical cable, lens, front isolator, light splitting piece, the polarizer, 45 degree of filters, rear isolator and optical fiber receive modules are positioned on straight line.
As preferably, described 45 degree of filter angles of inclination are 45 degree.
The beneficial effects of the utility model: the utility model structure is simple, compact and reasonable, fast easy to assembly, connect reliable, because optical transmitting set and optical receiver are spatially separate, the scattered light that the utilizing emitted light that therefore can reduce light emitting devices is formed due to scattering or reflection and reverberation cause crosstalk to light receiving element, ensure the receptivity of light receiving element; Further, when described incorporated light transmitting-receiving subassembly is applied in passive optical network, effectively can improves the light transmitting-receiving performance of optical network unit, reduce the error code caused due to crosstalk, promote Consumer's Experience.
