Description
Technical field
The utility model belongs to optical communication equipment field, is specifically related to a kind of radio and television optical receiver that cable television system uses.
Background technology
In fiber optic communication systems, the task of optical receiver is with minimum additional noise and distortion, recover the information entrained by light carrier after Optical Fiber Transmission, therefore the output characteristic concentrated expression performance of whole optical fiber telecommunications system of optical receiver.The light signal that optical sender is launched after transmission, not only amplitude fading, and impulse waveform also broadening, the effect of optical receiver is exactly detect the faint optical signal through transmission, and amplify, shaping, regeneration former signal transmission.
The radio and television optical receiver function of prior art is simple, it is unreliable to run, easily break down, and modal fault is that power supply and optical transmission signal are unstable, if power failure needs to change power supply timely, but user is easily caused to watch because maintenance personal can not keep in repair timely; In addition, optical transmission signal is unstable mainly occurs what the loss of signal caused because bending occurs the optical fiber in optical receiver, is therefore badly in need of the situation being carried out by the optical fiber in optical receiver reasonably fixedly preventing jitter.
Utility model content
The purpose of this utility model is to provide a kind of failure rate is low and the radio and television optical receiver of convenient for maintaining.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of radio and television optical receiver, comprise shell, inner bag and opto-electronic conversion electronic component, described opto-electronic conversion electronic component is arranged on inner bag, described shell is made up of the upper cover mutually mated and lower cover, described upper cover and lower cover are all in the rectangular structure without top, upper cover and lower cover are connected through the hinge, in described upper cover, inner bag is set, described inner bag is arranged optical fiber winding mechanism, power supply module groove is set in described lower cover, described power supply module groove edge is provided with wire casing, in power supply module groove, power supply module is set, power supply module is connected by cable with inner bag, described cable is provided with automatic power-supply switch.
Preferred: described optical fiber winding mechanism is made up of multiple line card, line card circumferentially shape arrangement, the radius of a circle of described line card composition is greater than the radius of curvature of optical fiber.
Preferred: described line card is 8, line card is circumferentially shape arrangement uniformly.
Preferred: described power supply module groove is 2, is distributed in the left and right sides of lower cover.
Preferred: the perisporium top of described upper cover is provided with buffer part, the perisporium top of described lower cover is provided with groove, and buffer part and groove cooperatively interact.
Preferred: described buffer part is made up of rubber blanket.
The utility model has following beneficial effect: use such radio and television optical receiver, two block power supply modules are set simultaneously, and can automatically switch, when there is power failure, stand-by power supply can be used to power, ensure optical receiver use and etc. to be repaired, simultaneously the optical fiber winding mechanism optical fiber avoided in optical receiver there will not be bending phenomenon, avoid it to occur light loss, ensure that the stable of broadcast television signal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model line card.
Embodiment
A kind of radio and television optical receiver as depicted in figs. 1 and 2, comprise shell, inner bag 3 and opto-electronic conversion electronic component, described shell is made up of the upper cover 1 mutually mated and lower cover 2, described upper cover 1 and lower cover 2 are all in the rectangular structure without top, upper cover 1 and lower cover 2 are connected through the hinge, in described upper cover 1, inner bag 3 is set, described opto-electronic conversion electronic component is arranged on inner bag 3, described opto-electronic conversion electronic component comprises photodiode, trans-impedance amplifier, LED display module and central control unit, its concrete layout is not the core content of this patent, those skilled in the art can realize with reference to prior art.
Described inner bag 3 is also provided with optical fiber winding mechanism, optical fiber winding mechanism is made up of 8 line cards 4, the uniform circumferentially shape arrangement of line card 4, described line card 4 is made up of with multiple crossbeam be at one end vertically connected with vertical beam a vertical beam, the end away from vertical beam of crossbeam is provided with back-off 41, line card 4 bottom welding is on inner bag 3, and the radius of a circle that line card 4 forms is greater than the radius of curvature of optical fiber, specifically should do corresponding adjustment depending on different types of optical fiber.Line card 4 is by optical fiber coiling and be fixed up, and prevents optical fiber from occurring bending phenomenon, ensures the stable of broadcast television signal.
2 power supply module grooves 5 are set in described lower cover 2, be distributed in the left and right sides of lower cover, power supply module groove 5 edge is provided with wire casing 8, in power supply module groove, power supply module is all set, one of them is stand-by power supply module, 2 power supply modules are connected by cable with inner bag 3, and described cable is provided with automatic power-supply switch.Wire casing 8 is for limiting cable position, and when there is power failure, automatic power-supply switch will switch power supply to stand-by power supply automatically, can not cause the signal interruption of user like this, and impact uses.
