  • Connector details1 x QSFP Network
  • Product typeNetwork Cable
  • Overall length9.84 ft (3 m)
  • 100 Gb/s aggregate throughput from four 28 Gb/s lanes
  • 84 ft reach for rack-to-rack InfiniBand and Ethernet links
  • Active signal regeneration maintains integrity over the full length
  • Halogen-free jacket meets class-4 QSFP+ power limits
  • 100 % tested on Mellanox gear for guaranteed interoperability

Mellanox LinkX QSFP+ Active Optical Cable

The Mellanox MFA1A00-E003 is a QSFP+ to QSFP+ active optical cable built for high-bandwidth InfiniBand and Ethernet fabrics. It targets data-centre operators and HPC clusters that need reliable 100Gb/s links between adapters and switches over distances up to 9.84 ft. Each of the four full-duplex lanes runs at up to 28Gb/s per direction, delivering an aggregated 100Gb/s throughput. The cable is 100% tested on Mellanox equipment to guarantee interoperability and consistent end-to-end performance.

Halogen-Free Build With Signal Regeneration

Active signal regeneration inside the QSFP+ shells allows the assembly to meet the class-4 power envelope while keeping the halogen-free jacket lightweight and flexible for dense rack routing. The SFF-8665 compliant connectors latch securely, reducing the risk of accidental disconnects during maintenance. Because the optics are integrated, there are no separate transceivers to seat or clean, which speeds deployment and lowers the chance of contaminated end-faces in daily operation.

Verify QSFP+ Port Compatibility And Reach

Confirm that both endpoints present QSFP+ cages rated for active optical cables and that the 9.84 ft length satisfies your rack-to-rack or intra-rack topology. The link operates under IEEE 802.3bm electrical specifications, so the host firmware must support the corresponding lane rates. No separate power budget or transceiver inventory is required beyond the available QSFP+ slots.

Questions about this item

What data rate does the QSFP+ interface on this MFA1A00-E003 cable support per lane?

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

What physical connector and length does this cable use for rack mounting?

It has QSFP+ male connectors on both ends and measures 9.84 ft, fitting standard QSFP+ ports in adjacent racks.

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

Insert each QSFP+ plug until the latch clicks; the active circuitry powers on automatically, but the protective dust caps must be removed first or the link will not come up.
