Server cable for PCI-E 5.0 links
This 0.5m adapter cable connects an MCIO SFF-8654 8I 74P port to two Oculink SAS SFF-8611 4I ports. It is built for high-performance server applications that require PCI-E 5.0 data rates. The male-to-male design uses OFC copper wiring and aluminum Mylar shielding. Locking connectors prevent accidental disconnection in dense chassis.
Practical limits of the SAS interface
The SAS interface carries both data and control signals over copper, so cable length and shielding quality directly affect signal integrity at PCI-E 5.0 speeds. Exceeding the rated reach or bending the cable too tightly increases bit errors. This 0.5m assembly is specified for short intra-chassis runs where the connector pitch matches the backplane layout. Longer runs need active or optical alternatives not covered here.
MCIO 8I to dual Oculink 4I split
The single MCIO 8I 74P connector breaks out to two Oculink SFF-8611 4I ends, halving the lane count per branch. This topology only works when the host controller and backplane both expect an 8I-to-2×4I split. Systems wired for straight 8I-to-8I or 4I-to-4I mapping will not link up with this cable.

Questions about this item
Should I choose the 0.5m or 1m length for my server build?
The 0.5m cable suits tight chassis routing; the 1m version gives more reach for larger enclosures or backplane-to-controller runs.
What does PCI-E 5.0 compliance mean for actual throughput on this cable?
It supports the 5.0 signalling rate end-to-end, so each Oculink SFF-8611 4I lane can carry the full bandwidth the host controller and drives negotiate.
How does the MCIO SFF-8654 8I 74P interface limit real-world performance?
The 74-pin MCIO 8I connector carries eight lanes; total throughput is capped by the PCI-E 5.0 x8 link rather than the cable itself.
