When to Use an 800G ACC Instead of DAC or AOC
- Use this OSFP112 active copper assembly for routes up to 5 m when passive 800G DAC reach is insufficient.
- Choose ACC when a copper construction, low latency, and approximately 2.5 W typical module power align with the link budget.
- Confirm OSFP112 electrical mode, CMIS behavior, cable length, and the permitted cable code on both hosts before deployment.
Compatibility and Acceptance Checklist
- Confirm the connector at each end: OSFP112.
- Confirm the required aggregate rate and host lane mode: 800G aggregate link.
- Measure the routed path, not the straight-line rack distance; the current datasheet states up to 5 m.
- Send switch/NIC part numbers and firmware versions for coding review; no platform-specific compatibility is assumed without validation.
- Check cable gauge, bend radius, and port-side mechanical clearance for the selected length.
- Specify commercial or industrial temperature requirements and the requested jacket/label/packaging details.
- At receipt, verify labels and part numbers, inspect latches and cable jackets, then test the complete link at the intended data rate.

Common Procurement Objections
Will it work in my switch or NIC?
Form factor and standards alignment are necessary but not sufficient. Send the exact host model, firmware, port mode, length, and coding requirement for a compatibility review.
Which length should I order?
The current datasheet lists up to 5 m. Measure the routed path, include a controlled service loop, and avoid ordering unnecessary slack.
Should I use DAC or AOC instead?
Use passive DAC for the shortest supported route and lowest cable power. Use AOC when the route, cable bulk, or EMI environment favors optics.
Can BWNFiber customize the assembly?
Datasheet ordering tables include standard and/or custom entries. Submit the endpoint, length, label, jacket, coding, temperature, packaging, and quantity requirements for feasibility confirmation.
