Vszerda Oculink Cable PCIe 4.0 SFF-8611 4i Male Extension 200 cm

Oculink PCIe 4.0 Extension Cable

This Oculink SFF-8611 cable connects a mini PC or portable device to an external GPU enclosure, delivering PCIe 4.0 bandwidth over a 200 cm male-to-male link. It is built for users who need desktop-class graphics performance from compact systems such as the GPD G1 or OneXGPU. The 42-pin straight connectors provide a direct 64 gigabit per second pathway without an intermediate adapter.

Build Integration and Space Savings

The 6.6 foot length routes around tight chassis corners and reaches an eGPU dock placed on a desk or shelf. A compact, braided jacket slips into narrow gaps behind mini PCs, freeing internal slots that would otherwise be occupied by a full-length graphics card. No extra power brick or active repeater is required; the cable draws signal power from the host port alone.

Bandwidth Headroom and Limits

Four lanes of PCIe 4.0 at 16 GT/s per lane supply 64 gigabits per second, enough for modern mid-range GPUs and high-speed SSD arrays in external enclosures. The link saturates when a single device demands more than four lanes or when the host controller is limited to PCIe 3.0 speeds. Buyers needing dual-GPU bandwidth or longer runs beyond 200 cm should plan a different interconnect.
