Vszerda OCuLink SFF-8611 8x to Dual SFF-8643 4x Active Cable 50cm

SKU CH-52FB-XF4QV

Connects an OCuLink SFF-8611 8x controller to two SFF-8643 4x devices with a 50 cm active cable supporting 16 Gbps data rates

Cable Length 50 cm

  • Connect internal backplanes to OCuLink controllers
  • SFF-8611 80-pin male to dual SFF-8643 36-pin male
  • Active latch secures each connection
  • Data transfer rate up to 16Gbps
  • 50 cm cable length for compact builds

Vszerda OCuLink SFF-8611 8x Active Cable

This Vszerda active cable converts a single OCuLink SFF-8611 8x 80-pin male port into two SFF-8643 4x 36-pin male connectors for internal SSD data links. It suits builders attaching a backplane or drive cage to a controller that only exposes an OCuLink 8x interface. The active latch on each plug secures the connection against vibration inside a chassis.

Sustained 16Gbps signalling over 50cm

Active circuitry inside the cable maintains signal integrity at up to 16Gbps across the full 50cm run, so throughput does not degrade under continuous heavy I/O the way a passive equivalent might. The 8-lane source is split cleanly into two 4-lane paths without protocol conversion, keeping latency predictable for storage arrays or compute accelerators.

Replaces a passive 8x-to-dual-4x assembly

Install this when a passive cable of the same length fails link training or drops lanes under load, or when the controller vendor specifies an active assembly for 16Gbps operation. It is not for external enclosures that require a different bulkhead connector, nor for systems lacking an OCuLink 8x 80-pin host port.

Questions about this item

How much power does the active 50 cm cable draw when it runs continuously?

The active cable uses its built-in signal conditioning to sustain 16 Gbps across the 50 cm length without an external power adapter.

What host connector must the system already provide for this cable to function?

The host needs an OCuLink SFF-8611 8x 80-pin male port to accept the cable's primary connector.

Will the dual SFF-8643 4x ends mate with a backplane that uses 36-pin connectors?

Each branch ends in a 36-pin SFF-8643 4x male connector with an active latch for secure mating.
