10Gtek SFF-8644 to QSFP+ SAS cable 4.92 ft

SKU CH-WZJ6-3PWPQ

Connects SFF-8644 and QSFP+ ports for 10 Gbps per channel SAS links at 4.92 ft

  • TypeCable Connectors
  • ColorBlack
  • Length4.92 ft.
  • Connector Number2

Length 3.28 ft.

Style QSFP to SFF-8644

  • 10 Gbps per channel for high-throughput links
  • SFF-8644 to QSFP+ hybrid connects SAS to 40 GbE gear
  • 100 Ohm impedance maintains signal integrity
  • 30 AWG construction enables flexible routing
  • Pull-tab release eases dense rack insertions

External Mini SAS HD connectivity

This 10Gtek cable links an SFF-8644 port to a QSFP+ port using a 4.92 ft hybrid assembly. It targets server and switch builders who need 40 GbE density across adapter cards and storage controllers. The black 30 AWG construction carries four lanes at 10.0 Gbps each with 100 Ohm impedance. Compliance covers QSFP MSA and SAS 3.0 specifications.

Replacing legacy copper interconnects

The hybrid design replaces separate SFF-8644 and QSFP+ patch cords when consolidating ports on a single run. Pull-tabs on both connectors speed removal in dense racks without tools. The jump is worth it when a controller or switch requires direct SFF-8644 attachment but the peer device only presents QSFP+. Single 3.3 V operation keeps power draw low across the link.

Four-lane headroom for 40 GbE

Each of the four channels delivers up to 10 Gbps, giving aggregate throughput suited to 40 Gigabit Ethernet and SAS 3.0 traffic. The 100 Ohm controlled impedance and precision skew control preserve signal integrity at the rated rate. Runs exceeding the 4.92 ft length or environments needing higher per-lane bandwidth fall outside the cable's rated envelope.

Questions about this item

What clearance does the SFF-8644 pull-tab need when plugging into a Mini SAS HD port?

The pull-tab on the SFF-8644 connector requires enough rear space to pull straight back; allow at least the tab length plus finger room behind the port.

Which end of the hybrid cable goes into the server HBA and which into the switch QSFP+ port?

Connect the SFF-8644 end to the host-bus adapter and the QSFP+ (SFF-8436) end to the 40-Gigabit Ethernet or InfiniBand switch port.

When should this 30 AWG, 100-Ohm cable be replaced in a SAS 3.0 link?

Replace the cable if link errors appear, if the pull-tabs no longer latch securely, or after any sharp bend that could damage the 30 AWG conductors.
