Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices to a computer. Devices can either be attached directly to a PCI bus as an integrated circuit or through an expansion card that plugs into a PCI bus slot. PCI NICs slide into an expansion card slot on the PC chassis and then plug into an internal PCI bus socket (or connector) on the PC’s motherboard for providing Ethernet connectivity over fiber to desktop PCs.
PCI network adapters use either 32-bit or 64-bit buses. Most 32-bit PCI NIC cards will fit and function in a 64-bit PCI-X slot, but the bus clock rate or transmission speed will be limited to the frequency of the slower card. Many 64-bit PCI NIC cards are designed to work in 32-bit mode if inserted in shorter 32-bit connectors but will incur some loss of performance.
Transition Networks’ PCI NICs provide for simple integration of fiber at the desktop in PCs that traditionally use copper cabling for networking. Our PCI NICs come with both standard height and low-profile brackets (unless otherwise specified), which can be applied to fit the particular PCI slot on the chassis of the PC. Our adapters are also available in Fast Ethernet and Gigabit Ethernet speeds. View our PCI NICs below.
