PCI Express® Standard Connectors | Samtec

The PCI Express® in an I/O interconnect bus standard (which includes a protocol and a layered architecture) that expands on and doubles the data transfer rates of original PCI. PCI Express® is a two-way, serial connection that carries data in packets along two pairs of point-to-point data lanes, compared to the single parallel data bus of traditional PCI that routes data at a set rate.

Initial bit rates for PCI Express® reach 2.5 Gbps per lane direction, which equate to data transfer rates of approximately 200 Mbps. PCI Express® was developed so that high-speed interconnects such as 1394b, USB 2.0, InfiniBand™ and Gigabit Ethernet would have an I/O architecture suitable for their transfer high speeds.

Samtec offers products that meet the PCI Express® form factor as well as connectors and cables that are capable of PCI Express® speeds.
