100GbE QSFP active fibre adapter

This Mellanox Technologies MFA1A00-C003 is a 3 metre active fibre cable built for 100 Gigabit Ethernet links. It suits data-centre operators and high-performance computing clusters that need reliable short-reach connectivity between QSFP ports. The LSZH jacket meets low-smoke, zero-halogen requirements for regulated environments. It is not intended for copper-based deployments or longer-distance runs beyond the supplied length.

Capacity and headroom

The cable carries 100 Gb/s of Ethernet traffic across its full 3 metre span without signal regeneration. Bandwidth headroom matches the 100GbE lane rate, so typical east-west cluster traffic and storage replication fit comfortably. Runs out when the link distance exceeds 3 metres or when a break-out to multiple lower-speed ports is required, as the assembly is a fixed single-channel QSFP-to-QSFP pair.

Build quality and daily implications

Weighing 0.3 kg, the assembly is light enough for dense patch-panel routing yet robust enough for repeated re-seating. The LSZH outer sheath resists flame spread and emits minimal toxic smoke, simplifying compliance in raised-floor and plenum spaces. QSFP connectors latch securely, reducing accidental disconnects during cable management. No external power adapter is needed because the active circuitry draws power directly from the host ports.

Questions about this item

Will the 100GbE QSFP active fiber adapter connect to my existing QSFP equipment?

The adapter uses a QSFP form factor for 100GbE links; check that your switch ports also support 100GbE QSFP to match the 100Gb/s rate.

How can I verify the 3m active fiber cable is operating at 100Gb/s after installation?

Confirm the link negotiates at 100Gb/s in your switch port statistics and run a traffic test to validate throughput.

Does the MFA1A00-C003 package include only the 3m cable or are transceivers supplied separately?

The 3m active fiber cable arrives as a complete assembly with QSFP ends attached; no separate transceiver modules are required.
