Fervit MCIO 38Pin Male to SFF-8611 Oculink 4X Extender Cable 50cm

Fervit MCIO 38Pin to SFF-8611 Extender

This new Fervit cable connects a 38-pin MCIO male interface to an SFF-8611 Oculink 4X port over a 50 cm length. It is built for data-centre, networking and telecommunications systems that run SAS, PCIe or Ethernet protocols. The assembly supports cable-to-board and card-to-board layouts, including chip-to-chip and chip-to-module links. Installers simply plug each end into the matching device or external drive.

Upgrade from shorter or lower-speed interconnects

The 50 cm reach lets engineers route signals across larger chassis or between adjacent racks without signal degradation. Moving to this extender is worth it when existing cables limit placement options or cannot sustain the 24 Gbps rate required by modern SSD arrays. It replaces fixed-length harnesses that restrict airflow or cage density. The design suits both board-level and card-edge installations where flexible high-speed channels are needed.

Practical limits of the MCIO interface

The MCIO standard tops out at 24 Gbps per lane, so aggregate throughput depends on the host controller and drive capabilities. Cable length is fixed at 50 cm; longer runs would require active retimers or a different media type. The connector pair is keyed for 38-pin MCIO male to SFF-8611 only, preventing mismatched pinouts. Users must verify that both endpoints support the same protocol and lane count before deployment.
