Abstract
The invention belongs to avionics field and especially relates to a long-distance 1394B transmission apparatus with a large plugging number. The long-distance 1394B transmission apparatus with a large plugging number comprises a metallic housing 1, and a quartered coaxial pin and power interface 2 for providing power and transmitting electric signals. One end of a photoelectric converting module 7 is connected with the quartered coaxial pin and power interface 2. The other end of the photoelectric converting module 7 is connected with an optical receiving pin 4 via a receiving fiber 3, and an optical transmitting pin 5 via a transmitting fiber 6. Compared with a product using fiber transmission, the long-distance 1394B transmission apparatus with a large plugging number is not required to independently design a photoelectric converting circuit if being used to transmit signals. Therefore, the internal space of an airborne product can be saved and difficulty in photoelectric mixing wiring in an airborne product cabinet can be prevented.

Background technology
1394B bus is a kind of high-performance serial data bus, because it takes up room little, cheap, speed is fast, topology flexibly, each port is that node is again the features such as relaying, make it in air line bus, occupy one seat, yet the raising along with transmission digit rate, the distance that adopts metal medium cable to carry out 1394B transfer of data constantly shortens, the speed of the 1394B bus on therefore current airborne product is generally limited under 400Mbit mode of operation, transmission range is 20 meters of left and right, and while adopting optical fiber to carry out the transmission of 1394B bus data, again because optical fiber connector plug number of times is too low, having limited it often can only be applied in not in the environment of plug, above shortcoming has seriously restricted the application of 1394B in aviation bus field.
Summary of the invention
Goal of the invention: provide a kind of high plug number of times remote 1394B transmitting device, do not need to design separately again photoelectric switching circuit, can save airborne products inner space, and avoid the difficulty that in airborne products cabinet, photoelectricity mixes wiring.
Technical scheme: the remote 1394B transmitting device of a kind of high plug number of times, comprise metal shell 1, be arranged on four minutes coaxial pins that power supply and transmission of electric signals are provided and power interface 2 in metal shell, photoelectric conversion module 7 one end are connected with four minutes coaxial pins and power interface 2, and the other end connects respectively to receive optical fiber 3 and send optical fiber 6 and is connected with light-receiving pin 4 and light transmission pin 5.
Described four minutes coaxial pins and power interface 2 are electrical connector pins.
The metal shell that described metal shell 1 is sealing.
Beneficial effect:
(1) while using the present invention to carry out the transmission of 1394B signal, there is the profile the same with electric connector, dismounting mode and plug number of times, can use as general electric connector simple and convenient;
