Recently, good news came from China's information and communication technology group, and China's optical communication technology has once again made breakthrough progress. The State Key Laboratory of Optical Fiber Communication Technology and Network, National Information Optoelectronics Innovation Center, Fiberhome Communications and Optoelectronics Technology have jointly conducted research on the optical transmission system of 1.06 Pbit/s ultra-large capacity WDM and space division multiplexing in China. The transmission capacity is 10 times the maximum capacity of the commercial single-mode optical fiber transmission system, and the data stored in about 130 1TB hard disks can be transmitted in one second. The experiment uses domestically the most advanced research results in optical transmission system technology, optical device and optical chip technology, and fiber optic cable technology, marking China's research field in the field of "ultra-large capacity, ul

The current smart home technology mainly refers to communication or control protocols. Professionally, it mainly involves two parts: hardware interface and software protocol. In general, the market is mainly divided into wireless communication, wired communication and power carrier. Wired mode RS485 IEEE802.3 (Ethernet) EIB/KNX LonWorks X-10, PLC-BUS PLC-BUS overview CresNet, AXLink, etc. In addition to X-10, PLC-BUS, there is almost no communication technology specifically developed for the smart home industry. What is interesting is that the X-10 power line carrier technology was successfully developed as early as the 1970s. In the field of application and home automation, it was introduced and promoted in China around 2000, but the market situation has been difficult to open. The main reason why it is difficult to widely promote is that in addition to the equipment cost and people's needs, it is also the various technologies. problem. Why has power line carrier techno
