PCIe x16 Gen4 Host Cable Adapter

PCIe x16 Gen 4 host interface board with PCIe quad SFF-8644 cable connectors as used in the PCISIG PCI Express External Cable Specification can be configured as x16, two x8, and two x4 or four x4 cable ports. The cable adapter operates in host or target mode with a DIP switch setting change.

PCIe (PCI Express) is a fast internal interface, which can be connected to a telecommunication server or to a computer system, multiple servers and modules. The transmission technology is based on two differential cable pairs, so-called links or lanes, one of which takes care of the data transmission and the other to receive data. Altogether can be bundled up to 32 of these links in order to increase the speed as much as possible. PCI Express offers significantly higher performance than Ethernet or USB and is ideal for time-critical applications that rely on high-speed I / O. With no software installation is required, the extension can be quickly and easily implement reliable and inexpensive.

Among the major PCIe expansion components include expansion card, PCIe cable adapters and backplanes. These are available in different designs, so there is a suitable product for every need and requirement. Cable with bandwidth of x1 to x16 and lengths from 1m to 100m enable high performance over long transmission paths. Cable Adapter cards offer thanks to numerous sizes and bandwidths optimal conditions for the use in various application requirements. The backplanes offered for PCI Express 1.0 to 4.0, optionally with one to twenty slots are perfect to add existing systems, additional PCIe slots
