The Contrastion Of USB Connector And IEEE 1394 Connector
As the most basic components of whole interconnect system, the appearance, transfer rate or to the product's performance of USB and IEEE 1394 connectors have a huge improvement. USB connector has developed to 2.0 version from the the earlier 1.1 version and the data transfer rate increased from 12Mbps to 480Mbps. The transfer rate of early IEEE 1394 connector has up to 400Mbps, while the standard 1394b connector can achieve the maximum transfer rate of 800 Mbps. It also plans to launch P1394b future specifications which will be able to use the fiber optic and CAT-5 cable, and the speed will increase to 3200 Mbps.
The application areas of IEEE 1394 Connector is more specialized to USB connectors, such as network products. It is more suitable for transmission distanct and larger amount of data. USB connectors are used in popular consumer electronics products, USBconnector is also turning to wireless products, such as Bluetooth and other fields. Digital cameras, card readers, digital cameras and other products are mainly used Mini1394 connector, the small size, high transmission speed make Mini1394 be popular in the future markets.
IEEE 1394 Connector and USB connector connection are also different in the structures. When connect USB Connector,it must be at least one computer, and must be required to achieve HUB interconnection, the network can connect up to 127 devices. IEEE 1394 Connector do not need a computer to control all devices, do not need HUB, IEEE 1394 Connector can connect multiple IEEE 1394 network, that is achieved in 63 sets with IEEE 1394 Connector. IEEE 1394 Connector device can also be used after the bridge to the other network connection up to achieve the unlimited connections.
