PCIe 5.0 MCIO x4 cable for data centres

This LetLinkSo cable connects two MCIO x4 male ports in a straight-through layout. It carries four lanes at 32 GT/s per lane, reaching a theoretical 128 Gbps. The 1.6 ft (50 cm) length suits dense server racks and storage arrays. It is built for SAS 4.0 and PCIe 5.0 equipment.

Signal integrity over copper conductor

The 38-pin SFF-TA-1016 interface uses a 0.6 mm pin pitch to reduce crosstalk and preserve fidelity across the link. Copper conductors handle the 128 Gbps aggregate rate without active components. The black jacket is rated for standard server airflow and operating temperatures.

Four-lane MCIO x4 male-to-male link

This part only works where both endpoints present an MCIO x4 male receptacle and require a PCIe 5.0 or SAS 4.0 x4 connection. It cannot bridge to U.2, U.3, OCuLink, SlimSAS or single-lane ports. Buyers needing longer runs, right-angle exits or different pinouts must source another cable.

Questions about this item

How do I connect the straight male SFF-TA-1016 38-pin MCIO x4 connectors, and what step is often missed?

Align the keyed 38-pin MCIO x4 male plugs with the matching female ports on the backplane and controller, then press straight in until the latch clicks; the step often missed is verifying both latches are fully engaged so the 32 GT/s lanes stay seated.

What maintenance or replacement will this copper-conductor MCIO cable need over time?

The copper conductors and UL-listed jacket are rated for continuous operation; inspect the latch tabs and connector housing during scheduled server maintenance and replace the cable only if a latch is broken or the jacket shows cuts.

At what point does signal integrity become the limiting factor during sustained PCIe 5.0 traffic?

The 50 cm length is designed to meet PCIe 5.0 channel-loss budgets at 32 GT/s; the first limit under sustained load is the connector-to-connector insertion-loss margin, not the copper conductors themselves.
