Arista AOC-D-D-400G-30M | 400G QSFP-DD AOC, 30m Multi-Mode Fibre, 8x 50G PAM-4

Q: What platforms is the AOC-D-D-400G-30M compatible with?
A: This cable is designed for Arista 400G QSFP-DD platforms including the 7060X4, 7050X4, and 7368X4 series. It is QSFP-DD MSA compliant, so it may also be compatible with other vendors' QSFP-DD ports that support 400GbE AOC connections — verify with your switch vendor before deployment.

Q: Does this cable require any field termination or preparation?
A: No. The AOC-D-D-400G-30M is a fully pre-terminated, plug-and-play cable. Simply insert the QSFP-DD connectors into the corresponding ports on both ends — no splicing, polishing, or field termination is required.

Q: What is the difference between an Active Optical Cable (AOC) and a Direct Attach Cable (DAC)?
A: A DAC uses copper twinax cabling and passive or active electrical signal amplification, typically suited for very short reaches (under 5m passive, up to ~10m active). An AOC like the AOC-D-D-400G-30M converts the electrical signal to optical at each end, transmitting over multi-mode fibre — enabling longer reaches (up to 30m in this case) with lower weight and improved EMI immunity compared to copper DAC.

Q: Is Digital Diagnostic Monitoring supported?
A: Yes. The AOC-D-D-400G-30M supports Digital Diagnostic Monitoring (DDM), allowing network management systems to monitor real-time parameters such as temperature, transmit power, receive power, and voltage for proactive link health management.

Q: Why choose an AOC over discrete transceivers for 400G interconnects?
A: AOCs offer a lower total cost and reduced power consumption per bit compared to using two separate 400G transceivers with a patch cable. They also simplify cable management with a lighter, thinner fibre jacket (LSZH), making them ideal for high-density data centre spine-leaf and HPC cluster interconnects.
