Embodiment
As shown in Figure 1, the utility model is interconnected and is formed by network control unit 1, photoelectric conversion unit 2, power circuit 3.Wherein, network control unit 1 external memory storage 12, Network Interface Module 13, communication interface modules 14, temperature detecting module 15, LCD MODULE 16, reset circuit 17 and the crystal oscillating circuit 18 that comprise ARM chip 11 and connect ARM chip 11 respectively.External memory storage 12 is connected with the extension storage space with ARM chip 11, Network Interface Module 13 sends to the information of the photoelectric conversion unit 2 that ARM chip 11 collects in the Ethernet, communication interface modules 14 is as required to monitor a plurality of photoelectric conversion units 2 from cabinet, temperature detecting module 15 is connected with ARM chip 11 by the I2C bus, the temperature information of the cabinet that collects is passed to ARM chip 11 to be handled, LCD MODULE 16 is connected with ARM chip 11 and shows that to carry out data in real time reset circuit 17 and crystal oscillating circuit 18 are in order to ensure ARM chip 11 operate as normal.Photoelectric conversion unit 2 is composed in series successively by light transceiving integrated module 21, photoelectric medium conversion chip 22, isolating transformer 23, RJ-45 interface 23, light transceiving integrated module 21 is by converting the light signal that transmits next this locality or 4B5B code system far from optical fiber to the signal of telecommunication of 4B5B, link to each other with photoelectric medium conversion chip 22 then, the signal of telecommunication of 4B5B is converted again to the signal of telecommunication of MLT-3 code system, link to each other with RJ-45 interface 23 with isolating transformer 23 successively at last, the signal of telecommunication is carried out being sent in the network after a series of processing.
