Tencent Science and technology news June 9, in Apple last week, "Apple Global Developers Conference" (Worldwide Developers Conference, hereinafter referred to as "WWDC"), the company announced the icloud cloud storage and cloud computing services strategic adjustment. It is understood that the company's goal is to achieve the user data between the iOS and OS X platform of the flow between the two, and for such as Dropbox and Facebook rivals pose a further threat.

Communication Technology. Power Line Communication has a history of decades. It is a technology that can transmit remote data and voice Communication over Power lines. Because the power grid has a huge coverage, people have come up with the idea of using power lines to achieve broadband access.
Power line network applications Power Line Carrier data signal), the low-voltage distribution network as the communication medium to achieve Internet broadband access, home users through the power socket
When it comes to Ethernet interfaces, it will always remind you of Coupled modular RJ plug and Jack connector. Since the concept of structured Telecom cabling, such interfaces have dominated the telecom market. Previously, from the late 1960s s, almost every sold phone headset had such two pair of connectors. There is no doubt that RJ plug and socket interfaces are widely used. However, as the data transmission speed approaches 10 Gb/s, they seem to be insufficient. Moreover, most manufacturers
System is highly flexible, with changes in the location of various devices and LAN without re-wiring. As long as the cabling is adjusted properly in the cabling system, the requirements can be met. Structured Cabling is generally divided into six subsystems.
1-1. workspace subsystem Work Area) and Network DesignThe workspace subsystem consists of a connection between a terminal device and an information outlet. The information points are composed of
, to ensure the reliability and stability of the entire system, the cabling engineers of Sihai optical fiber will work with the construction personnel throughout the construction site to lay cables in the building. The laying process will also be completed in strict accordance with the LUCENT and AMP standards, from horizontal cables, trunk cables to the installation of each information outlet. Connections to information sockets are implemented accord
exquisite Terminals-humanized combination of technology and AestheticsAs people work longer and longer, comfort and ergonomics have gradually become the most important topics in the workplace. Offices, meeting rooms, and hotel rooms are almost the places for every staff to perform daily activities. Actassi is a series of end products that combine the aesthetic and powerful functions of the technology to ensure real-time communication between users' personal data and voice information, so as to
Integrated WiringSystem Engineering, regardless of its importance or comprehensiveness, is a key project in the main project of intelligent building or intelligent community, especially the installation and construction, with a certain degree of creativity and perfection, so that the intention of the Integrated Wiring System Engineering design can be fully implemented.

The RJ45 connector looks like a telephone connector used at home, but it must be wider. The telephone connector (the small crystal head at the end of the telephone line that can be inserted into the telephone outlet) contains four wires, and RJ45 uses eight.
