A PCI Express (PCIe) signal switch, sometimes referred to as a PCIe switch or PCIe multiplexer is a component used in computer systems to handle and transport PCIe signals. It enables switching between various PCIe interfaces or allowing numerous PCIe devices to share a single PCIe interface.
A high-speed serial bus standard called PCIe is frequently used to attach numerous parts, like graphics cards, network cards, storage devices, and other peripheral devices, to the motherboard of a computer.
To increase the number of PCIe lanes that are accessible and allow for the connection of more devices, PCIe switches are employed. A PCIe signal switch’s main job is to link devices and give users control over PCIe signal routing.
Depending on the necessary level of extension, PCIe switches can be found in a variety of designs, including 1-to-2, 1-to-4, and even larger switches.
They often have several downstream ports to connect to the PCIe devices and multiple upstream ports to connect to the PCIe root complex of the host system (the primary PCIe interface on the motherboard).
These switches are frequently used in high-performance computer systems, servers, workstations, and other applications where a lot of PCIe devices are required or extra PCIe connection is needed outside of what the motherboard can provide.
A PCIe signal switch, in general, offers a scalable and adaptable method for managing PCIe connections inside of a computer system, enabling effective use of PCIe resources and boosting the system’s expandability.
The Global PCI Express Signal Switch Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
