Fiber optic adapter type introduction and application field

according to different types of optical fiber network card supported by bus, can be divided into the ISA, PCI, USB, fiber optic adapter, etc.

　　ISA( Industry standard architecture) Fiber optic adapter - — ISA bus development in 1981, is the standard bus architecture of IBM compatibles, due to its transmission rate only 9 MBPS, ISA bus is no longer recognized type now, in reality it's hard to find it again.

　　PCI( Peripheral component interconnect) Fiber optic adapter - — PCI bus development, in 1990, to replace the earlier the ISA bus, it has 32 bit and 64 bit data width ( The equivalent of 133 MB/s and the 266 MB/s data transfer rate) 。 This type of optical fiber network card originally used for servers, after gradually develop to can be used for PC. Now, the PC optical fiber network card most be integrated in the motherboard, therefore, PCI optical fiber network card has been replaced by other bus fiber optic adapter, such as PCI - X or USB optical fiber network card.

PCI - X optical fiber network card - — PCI - X is a kind of enhanced PCI bus technology, it USES 64 - bit width to transmit data, data transfer rate of up to 1066 MB/s, in general, PCI - X can be backward compatible with PCI optical fiber network card.

PCI - E optical fiber network card - — PCIe is currently the most widely used standards, mainly used in computer and server motherboard. Nowadays, PCIe fiber nic has five versions, each version support vomit swallowing quantity different. Application field

computer optical fiber network card - — Nowadays most of the computer motherboard built-in optical fiber network, support 10/100/1000 MBPS transmission rate, used for one computer to another computer or network communication.

server optical fiber network card - — Server is the main functions of the optical fiber network is the network traffic management and processing, relative to the optical fiber network CARDS on the computer, server fiber optic adapter usually require a higher transmission rate, such as 10 g, 25 g, 40 g or 100 g. In addition, because the server optical fiber network card has a controller, low CPU usage, so more tasks can be performed in the CPU. In order to meet the different needs of users to optical fiber network, rapid, FS) Can provide 25 g / 10 g / 40 g optical fiber server nic, adopt Intel controller, support network virtualization and optimization function.
