Arista AOC-O-O-400G-1M | 400G OSFP AOC, 8x 50G PAM-4, Multi-Mode Fibre, 1m

Q: What platforms is the AOC-O-O-400G-1M compatible with?
A: This AOC is designed and validated for use with Arista switches and routers equipped with 400G OSFP ports, such as platforms in the Arista 7800R3, 7500R3, and 7060X series. Its MSA compliance also provides broad compatibility with other vendors' OSFP 400G equipment.

Q: What is the difference between an AOC and a DAC cable?
A: A DAC (Direct Attach Copper) cable uses copper conductors and is limited to very short distances (typically up to 5m). An AOC (Active Optical Cable) uses optical fibre with active electronics at each end, enabling longer reach, lower EMI, and better signal integrity — making it ideal for distances of 1m to 30m in high-density data centres.

Q: What fibre type does this cable use?
A: The AOC-O-O-400G-1M operates over multi-mode fibre (MMF) at an 850nm wavelength. It is a pre-terminated cable assembly, so no additional fibre patch work is required — simply plug into your OSFP-equipped ports.

Q: Is this cable suitable for AI and HPC workloads?
A: Yes. The 400GbE AOC is specifically designed for high-performance computing (HPC) and AI/ML cluster interconnects where ultra-low latency, high bandwidth, and dense cabling are critical. The 1m length is ideal for top-of-rack and adjacent-rack switch-to-server connections.

Q: Can I purchase this AOC in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an authorised Australian B2B IT hardware reseller supplying Arista networking products including AOC and DAC cables. Orders ship fast across Australia with expert pre- and post-sales support available.

Q: What warranty is included with the AOC-O-O-400G-1M?
A: Arista provides a 1-Year Limited Hardware Warranty covering parts, repair, or replacement with a 10 business day turnaround, giving you confidence in long-term reliability for your data centre infrastructure.
