China Keystone Jack,Ethernet Wall Jack,Ethernet Wall Plate,Rj45 Keystone, we offered that you can trust. Welcome to do business with us.
RJ45 interface can be used to connect RJ-45 connectors. It is suitable for the network constructed by twisted pair. This port is the most common port, which is generally provided by Ethernet hub. The number of hubs we usually talk about is the number of RJ-45 ports.

In terms of core technology, the project should focus on improving performance, improving performance or reducing costs, and the project should make a difference in narrowing the technology gap and providing licensable data. In this grant, if the Federal Research Center or the National Laboratory is the main takeover, the cost sharing requirements should be voluntarily given up.
In terms of product development, the project should focus on research and development of basic application results, development or improvement of commercially viable materials, devices and systems. The selected projects should indicate the target market application and clearly indicate the price, efficiency and other proof feasibility. Required parameters. 
RJ45 is a type of different connectors (for example: RJ11 is also a type of connector, but it is used on the telephone); there are two different ways to arrange the RJ-45 connector: one is white orange, orange, white green, blue, white blue, green, white brown, brown; the other is white green, green, white orange, blue, white blue, orange, white brown, brown; therefore, there are also wires with RJ45 connector There are two kinds: straight line and interleaved line.
The RJ-45 port of the hub can be directly connected to terminal devices such as computers and network printers, and can also be connected with other hub equipment and routers such as switches and hubs. It should be noted that when connecting to different devices, the jumper method of twisted pair cable used is different.
DOE announces that solid-state lighting research projects will be funded and opportunities are currently being recruited
[High-tech LED News] Recently, the US Department of Energy announced that the solid-state lighting industry will receive two funding opportunities, the amount of funding will be directly used in the core technology research and product development of the Ministry of Energy research and development projects. The following categories of solid-state lighting research projects are currently being recruited, with a deadline of November 3, 2011.
