OCuLink SFF-8611 8x cable splitting to dual SFF-8639 U.2 connectors, 50cm length

Vszerda

Vszerda OCuLink PCIe SFF-8611 8x 8-Lane to Dual SFF-8639 U.2 4x Active Cable 50cm

SKU CH-6542-N9HQ2

Connects an OCuLink SFF-8611 8x host to two U.2 SFF-8639 drives at up to 16Gbps over a 50cm active cable

Cable Length 50 cm

  • Connects 8-lane OCuLink to dual U.2 backplanes
  • Active cable supports 16Gbps data transfer rate
  • 50cm length fits compact server chassis
  • 80-pin SFF-8611 male to dual SFF-8639 male
  • Active latch secures connection under vibration

OCuLink SFF-8611 8x to Dual U.2 4x Active Cable

This 50 cm active cable bridges an OCuLink SFF-8611 8x 80-pin male connector to two SFF-8639 U.2 male connectors. It supports data rates up to 16 Gbps for internal device connections such as backplanes. The active latch provides a secure lock to the mating part. System requirement is an OCuLink 8x 80-pin interface.

Replaces passive or shorter OCuLink links

The active design maintains signal integrity at 16 Gbps over the 50 cm length where a passive cable might degrade. Dual SFF-8639 endpoints let one OCuLink 8x port serve two U.2 devices. The upgrade is worth it when the host has a single SFF-8611 8x port and the build needs two U.2 connections without adding a second controller.

Suits builders linking one OCuLink 8x port to two

Ideal for server or workstation backplanes that expose SFF-8639 connectors. Not for users who need a single U.2 connection, a different cable length, or a passive cable for shorter runs. Also unsuitable for systems lacking an OCuLink 8x 80-pin host interface.

Questions about this item

Does the 80-pin SFF-8611 connector fit a standard OCuLink 8x controller port?

Yes, the cable uses an SFF-8611 8x 80-pin male connector that mates with any OCuLink 8x 80-pin interface on the controller.

How do you secure the active-latch connectors so they do not pop loose during drive swaps?

Push each SFF-8639 U.2 plug straight in until the integrated active latch clicks; the latch locks automatically and must be pressed to release.

When should the active cable be replaced if signal integrity drops?

Replace the cable if the controller reports link errors or the drives fall off the bus, as the active circuitry inside the 50 cm assembly cannot be serviced.
