Mellanox Technologies MFA1A00-E001 LinkX InfiniBand cable QSFP+ 3.28 ft

SKU CH-234A-N857M

Active optical cable with QSFP+ connectors carries four lanes at up to 28 Gb/s each for 100 Gb/s aggregate InfiniBand or Ethernet links

  • Cost-effective high-bandwidth fabric connectivity with Mellanox LinkX active optical cables
  • Aggregated 100Gb/s throughput via four 28Gb/s full-duplex lanes per direction
  • 100% tested on Mellanox equipment for guaranteed interoperability and end-to-end performance
  • Class-4 QSFP+ power consumption minimises environmental footprint
  • Halogen-free SFF-8665/IEEE 802.3bm compliant active fiber optic cable with signal regeneration

High-Bandwidth InfiniBand Link

This active optical cable connects QSFP+ ports in high-performance fabrics. It carries four full-duplex lanes for an aggregated 100Gb/s throughput. The assembly is built for Mellanox adapter and switch ecosystems. It suits clusters that need reliable 28Gb/s per lane signalling.

Halogen-Free Active Fibre Construction

The cable uses fibre optics with integrated signal regeneration to maintain integrity over its 3.28 ft reach. A halogen-free jacket meets modern environmental requirements. Class-4 QSFP+ power limits keep consumption low in dense racks. Each unit is 100% tested on Mellanox equipment before shipping.

Replaces Passive Copper At Longer Runs

Passive copper assemblies cannot guarantee 28Gb/s per lane at this distance without errors. The active design restores the signal so the link stays clean. The jump is worth it when cable trays exceed passive reach limits or when port density demands lower power per connection. Buyers who need copper pricing for very short runs will not benefit.

Questions about this item

What data rate does the QSFP+ interface support per lane and in aggregate?

Each of the four lanes transmits up to 28 Gb/s per direction, giving an aggregated rate of 100 Gb/s.

What physical connectors and cable length are required for this link?

The cable uses QSFP+ (M) connectors on both ends and is 3.28 ft long with a fibre-optic, halogen-free jacket.

How is the active optical cable installed, and what step is often missed?

Insert the QSFP+ modules until they click into the switch or adapter ports; the active circuitry is powered through the port, so no external power connection is needed.
