Arista AOC-D-D-400G-25M | 400G QSFP-DD AOC, 25m Multimode, 8x 50G PAM-4 Lanes

Q: Can I purchase the Arista AOC-D-D-400G-25M in Australia?
A: Yes. The AOC-D-D-400G-25M is available through iptrading.com.au, an Australian B2B IT hardware reseller offering fast shipping and expert support across Australia.

Q: Which Arista switches is this AOC compatible with?
A: This cable is compatible with Arista 400G QSFP-DD platforms, including switches and routers managed under Arista EOS and CloudVision. Confirm your platform's QSFP-DD port compatibility before ordering.

Q: What is the maximum reach of this Active Optical Cable?
A: The AOC-D-D-400G-25M supports a link length of 25 metres over multimode fibre. Arista's 400G AOC range is available in lengths from 1m to 30m for flexible data centre cabling.

Q: How does an AOC differ from a DAC cable for 400G applications?
A: Active Optical Cables (AOCs) use optical fibre rather than copper twinax, enabling longer reach (up to 30m), lighter weight, and smaller bend radius than DAC cables. AOCs are preferred for 400G deployments where runs exceed 5–7 metres or cable management density is critical.

Q: Does this cable require any configuration once installed?
A: No. The AOC-D-D-400G-25M is a pre-terminated plug-and-play assembly. Simply insert into compatible QSFP-DD ports on both ends — no field termination or additional configuration is required.

Q: Is the LSZH jacket required for data centre installations?
A: LSZH (Low Smoke Zero Halogen) jacketing is often mandated in enclosed or plenum data centre environments due to fire safety regulations. This cable's LSZH jacket makes it suitable for such deployments without requiring additional conduit.
