What is OCuLink?

A: The OCuLink interface is a PCI Express small connector standard developed by the PCI-SIG organization. Its full name is Optical Copper Link, which means optoelectronic composite connector. It was first proposed in 2013 with the aim of providing a more compact, flexible, and efficient PCIe expansion solution.

OCuLink can support different protocols such as PCIe 3.0 and PCIe 4.0, as well as storage protocols such as SATA and SAS. At present, the common OCuLink interface on the market uses two different connectors, SFF-8611 and SFF-8612, which are respectively used for the host side and device side. It can provide 4 PCIe channels, with a total bandwidth of up to 64Gbps.

The main application scenario of OCuLink interface is to provide high-speed PCIe expansion capability between mobile devices and external devices, such as external graphics cards, storage devices, network devices, etc. It can provide mobile devices with more powerful performance and functionality when needed, without the need to change their internal structure and size. It can also make external devices more easily compatible and connected to different host devices without the need for additional converters or adapters.

The Minisforum DEG1 graphics card docking station has a minimalist design, with the entire body made of metal material; Due to its open design, it claims to have no limit on graphics card length and supports up to Nvidia Geforce RTX 4090 and AMD Radeon RX 7900 XTX graphics cards.
Mnisforum DEG1 graphics card docking station provides PCIe 4.0x4 expansion interface, which can provide up to 64Gbps data transmission bandwidth.
