50cm PCIe 5.0 MCIO 4i 38Pin Male to SFF-8611 Slimline 4X Active Extension Cable, Mini Cool Edge IO High-Speed Data Cable for eGPU, NVMe SSD & High-Density Servers

This 50cm OCuLink active extension cable adopts standard Mini Cool Edge IO (MCIO) 4i 38Pin to SFF-8611 Slimline 4X interface, fully compliant with PCIe 5.0 specification and backward compatible with PCIe 3.0/4.0. Equipped with professional built-in signal amplifier, it maintains complete x4 64Gbps bandwidth without signal attenuation even at 50cm length, perfectly solving long-distance transmission bottlenecks of high-speed NVMe SSD and external graphics cards.

Both ends feature reinforced locking latch connectors to fix ports tightly, avoiding accidental disconnection during heavy-load continuous operation. The whole cable is wrapped with braided multi-layer shielding structure to isolate electromagnetic noise from power supplies and cooling fans, effectively preventing data errors, device offline and transmission lag.

It is widely applied for eGPU docking stations, U.2 NVMe solid state drive backplanes, high-performance mini workstations and IDC rack storage servers. The moderate 50cm length realizes flexible internal layout inside cramped compact chassis, improving hardware heat dissipation by separating high-temperature storage and graphics devices from motherboards.

Gold-plated internal pins deliver superior anti-oxidation conductivity for long-term stable use. Plug-and-play design requires no extra driver or auxiliary power supply, ideal for hardware modders, data center engineers and video rendering workstation builders to expand high-speed PCIe storage and graphics interfaces.
