MFA1A00-E010

Mellanox active fiber cable, IB EDR, up to 100Gb/s, QSFP, LSZH, 10m

Mellanox? MFA1A00-Exxx are QSFP28 VCSEL-based (Vertical Cavity Surface-Emitting Laser) active optical cables designed for use in InfiniBand 100Gb/s EDR systems. 100G EDR AOCs are the most popular interconnect used in very high-speed InfiniBand High Performance Computing (HPC) environments as they offer predictable latency, very low power (2.2W) and enable increased air flow, tighter bend radii and significantly longer reach compared to DAC cables. Since the AOC is hot pluggable, it is easy to install and replace.

MFA1A00-E010 has a standard SFF-8665 compliant QSFP28 port on the electrical side towards the host system. It contains four multi-mode fibers (MMF) optic transceivers per end, each operating at data rates of up to 26Gb/s.

MFA1A00-E010 offers selectable retiming per lane for both its optical transmitters and receivers for the 25-26Gbp/s rates, but the AOC also supports lower bit rates without retiming. The transmitters have programmable input equalizers and input squelch function, while the receivers have programmable output amplitude and pre-emphasis.

AOCs enable higher port bandwidth, density and configurability at a low cost, and reduced power requirement in the data centers, used extensively in cloud and supercomputers. Additionally, AOCs are widely employed for connecting NVIDIA GPU-based systems to InfiniBand networks and InfiniBand storage fabrics.

AOC cables offer the low-cost, high-value proposition and increased reliability over connectorized transceivers. They are lighter, more flexible, allow greater airflow, and support longer distances when compared with DAC cables.
