To achieve these goals, the technical solution adopted in the utility model is: a kind of Miniature optical fiber is to house type photoreceiver, it is characterized in that: include optical fiber input adapter, radio frequency out splice going splice, signal processing circuit and for connecting the USB power source joint of broadcast television set set top box USB interface, optical fiber input adapter, radio frequency out splice going splice, USB power source joint are connected with signal processing circuit respectively, optical signal enters photoreceiver internal circuit by optical fiber input adapter, by radio frequency out splice going splice output radiofrequency signal after process.
Further, this utility model also includes a shell, described signal processing circuit is arranged in the enclosure, described optical fiber input adapter is fixedly mounted on the end face of shell, radio frequency out splice going splice is arranged on the side of shell, and described USB power source joint is connected with described signal processing circuit by the wire of a traverse shell. Preferred mounting means can be the axis perpendicular making optical fiber input adapter, radio frequency out splice going splice.
Or, described optical fiber input adapter, radio frequency out splice going splice are respectively and fixedly installed on the end face of shell, bottom surface, and described USB power source joint is connected with described signal processing circuit by the wire of a traverse shell. Preferred mounting means can be the dead in line or parallel making optical fiber input adapter, radio frequency out splice going splice.
Or, described optical fiber input adapter, USB power source joint are respectively and fixedly installed on the end face of shell, bottom surface, and described radio frequency out splice going splice is connected with described signal processing circuit by the holding wire of a traverse shell; Length��30 centimetre of described holding wire. Preferred mounting means can be the dead in line or parallel making optical fiber input adapter, radio frequency out splice going splice.
The beneficial effects of the utility model are:
1, it is configured without Switching Power Supply inside receiver, also without external power supply adapter, USB interface either directly through radio and television Set Top Box obtains working power, greatly reduce the cost of photoreceiver product and then reduce network construction cost, improve the competitiveness of television network broadcast operator.
2, radio frequency out splice going splice is fixed on photoreceiver product, is directly connected with radio and television Set Top Box rf input port and is arranged on by photoreceiver on Set Top Box rf input interface, the loss of radiofrequency signal almost without. When radio frequency out splice going splice employing activity, only it is connected with photoreceiver product ontology by one section of holding wire less than 30 centimetres, then radio frequency out splice going splice is connected on the rf input interface of radio and television Set Top Box, owing to holding wire length is extremely short, the loss of radiofrequency signal is very little, the viewing effect of user can be greatly improved, improve the market competitiveness of television network broadcast.
3, being directly installed in radio and television Set Top Box external radio frequency joint or USB joint, it is not necessary to change radio and television Set Top Box or open Set Top Box and be operated, engineering construction debugging is convenient and swift.
