High speed expansions for connecting servers and PCIe / PCI devices
When it comes to networking servers and PCI Express devices, PCIe / PCI expansions are part of the high-speed standard. The expansions not only have a higher performance than USB and Ethernet, but are also more reliable and cost-efficient. No software installation means no overhead and low latency, which makes PCIe expansions attractive for a wide range of industrial applications.
High performance, low latency solutions
PCIe / PCI expansions and expansion systems offer a high-performance, low-latency solution for expanding PCIe slots outside of computers, laptops, workstations, servers or blade centers. You can choose from chassis systems with up to 16 slots and the appropriate power supply and cooling. You can also choose between server rack variants or desktop versions.

PCI Express life cycle
Compare all PCIe transfer rates
The transfer speed for PCIe is “oriented” to the version and the number of links or lanes. The higher the version and the more links, the higher the bandwidth and the higher the transfer speed. The bandwidth indicates how much capacity is available theoretically or at most for data transmission. However, the actual data rate is lower.
| PCIe | Bandwidth per link | PCIe x1 | PCIe x4 | PCIe x8 | PCIe x16 | Line Code |
|---|---|---|---|---|---|---|
| 1.0 | 2.5GT/s | 2.5GBit/s | 250MByte/s | 1GByte/s | 2GByte/s | 4GByte/s | 8b10b |
| 2.0 | 5GT/s | 5GBit/s | 500MByte/s | 2GByte/s | 4GByte/s | 8GByte/s | 8b10b |
| 3.0 | 8GT/s | 10GBit/s | 0.9846GByte/s | 3.938GByte/s | 7.877GByte/s | 15.754GByte/s | 128b/130b |
| 4.0 | 16GT/s | 20GBit/s | 3.9GByte/s | 7.877GByte/s | 15.754GByte/s | 31.508GByte/s | 128b/130b |
