OCuLink SFF-8611 8x cable to dual SFF-8643 4x connectors, 50cm

Vszerda

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

SKU CH-ETVV-GCCY7

Connects an OCuLink 8x controller to two SFF-8643 backplanes with 16 Gbps active signal integrity over 50 cm

  • Connects OCuLink 8x host to dual SFF-8643 backplanes
  • Active circuitry supports 16 Gbps data rates
  • 50 cm length fits tight server chassis
  • 80-pin SFF-8611 to dual 36-pin SFF-8643 male connectors
  • Active latch locks securely to mating port

OCuLink SFF-8611 8x active cable

This 50 cm active cable bridges an OCuLink SFF-8611 8x 80-pin male connector to two SFF-8643 4x 36-pin male connectors. It carries PCIe data at up to 16 Gbps and uses active latches to secure each mating part. The assembly is intended for internal connections between a controller and a backplane or drive cage.

Suits builders linking one 8-lane port to two

It serves systems that need to split a single OCuLink 8x interface into a pair of SFF-8643 4x links. Builders whose backplanes or controllers lack SFF-8611 ports, or who require longer reach than 50 cm, should look elsewhere.

Handles one 8-lane link split across two 4-lane

The 16 Gbps rate provides headroom for dual SAS or SSD connections sharing the upstream bandwidth. The fixed 50 cm length limits routing options in larger enclosures, and the cable cannot combine the two 4x links back into a single 8x device.

Questions about this item

Do I need a controller with an OCuLink SFF-8611 8x 80-pin port to use this cable?

Yes, the cable requires a controller or motherboard that provides an OCuLink SFF-8611 8x 80-pin interface for the host connection.

Can I connect this cable to a backplane that uses SFF-8643 4x 36-pin connectors?

The cable splits one OCuLink 8x 80-pin male end into two SFF-8643 4x 36-pin male ends, so it fits backplanes with those ports.

How do I verify the active cable is passing data at up to 16 Gbps after installation?

Check the controller BIOS or OS device manager to confirm the linked drives negotiate a 16 Gbps SAS connection on each 4x lane.
