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-Exxx 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-Exxx 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.

Frequently Asked Questions
What is the primary application for the Mellanox MFA1A00-E005 active optical cable? +
The MFA1A00-E005 is designed for high-performance computing and data center environments requiring 100Gb/s InfiniBand EDR connectivity. It serves as an ideal solution for short-reach, high-speed interconnects between switches, servers, and storage arrays, ensuring low latency and high bandwidth for bandwidth-intensive cluster applications.
Does the MFA1A00-E005 support backward compatibility with older InfiniBand generations? +
This cable is specifically optimized for InfiniBand EDR (Enhanced Data Rate) performance. While QSFP interfaces often maintain physical form factor compatibility, performance is governed by the transceivers and the protocols of the connected hardware. Users should ensure their switch or HCA ports are configured to support the 100Gb/s throughput required for EDR operation.
What are the physical construction benefits of the LSZH rating on this Mellanox cable? +
The LSZH (Low Smoke Zero Halogen) classification indicates that the cable jacket is engineered to emit minimal smoke and no halogen gases when exposed to high heat or fire. This is a critical safety requirement for modern data center deployments, ensuring compliance with strict building fire safety codes and protecting sensitive hardware from corrosive fumes.
How does an active fiber cable compare to standard passive copper DACs for 100Gb/s links? +
Active optical cables like the MFA1A00-E005 offer significantly lower weight and a much smaller cable diameter compared to passive copper DACs. This improves airflow management within dense rack environments. Furthermore, because it is an active cable, it provides superior signal integrity over its 5-meter reach, overcoming the distance limitations typically associated with passive copper options.
Are there specific power requirements for using the MFA1A00-E005 in a QSFP port? +
As an active cable, the MFA1A00-E005 draws power directly from the host QSFP port to operate its integrated optical transceivers. It is designed to operate within standard QSFP power consumption envelopes. When populating a switch with multiple cables, ensure your power budget accounts for the integrated optics to maintain stable port performance across the entire chassis.
Can the MFA1A00-E005 be used for 100GbE Ethernet deployments? +
While the MFA1A00-E005 is categorized as an InfiniBand EDR solution, the underlying QSFP interface is physically compatible with various high-speed standards. However, performance and reliability are best validated when used within a native InfiniBand ecosystem. Always verify your specific switch port settings and protocol compatibility if you intend to cross-reference this with Ethernet-based 100G gear.
What is the significance of the 5-meter length for this Mellanox AOC? +
The 5-meter length is a versatile 'sweet spot' for intra-rack or adjacent-rack connectivity. By utilizing active fiber optics at this length, you achieve a reliable, high-speed connection that avoids the signal degradation issues seen in copper equivalents. This length provides enough slack for clean cable management, reducing the risk of port stress or tight bend radii that could affect network uptime.
Is any specialized software configuration required to initialize the MFA1A00-E005? +
This cable is a plug-and-play solution. Upon insertion into a compatible QSFP port, the host device will automatically detect the transceiver and establish the link. There is no external software or firmware configuration required for the cable itself; the management and monitoring of the link are handled entirely through the switch or server operating system and its existing interface tools.
