800G DAC

BWNFiber 800G OSFP112 Active Copper Cable (ACC)

Use this cable when a pre-engineered assembly is preferable to separate optics and patch leads. The BWNFiber 800G OSFP112 ACC, also specified as a OSFP112 active copper cable, is built for a same-speed OSFP112 copper link that uses active equalization to cover the reach between a passive DAC and an AOC. A built-in linear equalizer compensates transmission loss without moving to an optical cable. Standard and custom ordering options should be confirmed against the host port, requested length, and environmental requirements before the BOM is approved.

Selection

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.
Choose an alternative when: Use passive DAC for the shortest supported route and lowest cable power. Use AOC when the route, cable bulk, or EMI environment favors optics.
Deployment Control

Compatibility and Acceptance Checklist

  1. Confirm the connector at each end: OSFP112.
  2. Confirm the required aggregate rate and host lane mode: 800G aggregate link.
  3. Measure the routed path, not the straight-line rack distance; the current datasheet states up to 5 m.
  4. Send switch/NIC part numbers and firmware versions for coding review; no platform-specific compatibility is assumed without validation.
  5. Check cable gauge, bend radius, and port-side mechanical clearance for the selected length.
  6. Specify commercial or industrial temperature requirements and the requested jacket/label/packaging details.
  7. At receipt, verify labels and part numbers, inspect latches and cable jackets, then test the complete link at the intended data rate.

Buyer Questions

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.

FAQ

800G OSFP112 Active Copper Cable (ACC) FAQ

What is the BWNFiber 800G OSFP112 Active Copper Cable (ACC)?

BWNFiber 800G OSFP112 Active Copper Twinax Cable (ACC) is designed for use in 800GBASE Ethernet. OSFP112 targets 112 Gb/s per lane in an 8-lane OSFP system. ACC is a re-drive solution with a built-in linear equalizer to compensate transmission loss, providing low power, low latency and low cost for high-speed data centers and AI applications. The assemblies meet and exceed 800 Gigabit Ethernet, InfiniBand EDR/HDR and temperature requirements. The page uses the supplied datasheet as the claim source; final host compatibility remains configuration-specific.

What link length is available for this ACC?

The current datasheet indicates up to 5 m. The usable length for a particular deployment still depends on the ordered part number, host electrical budget, route, and acceptance criteria.

Which interfaces does this cable connect?

This product is defined as OSFP112. Match the complete connector, lane mode, and endpoint role rather than relying on aggregate speed alone.

Do both ends need the same speed setting?

Both endpoints must support the selected interface and link mode. Auto-negotiation behavior varies, so configure and verify the ports using the host documentation.

How do I check OSFP112 compatibility?

Provide the two host model numbers, firmware versions, port type, port mode, required cable code, and planned length. A standards match does not by itself prove a host will accept every third-party cable code.

When should I choose ACC for this link?

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.

What should be included in an RFQ?

Include endpoint A and B, host models, firmware, port mode, length and service-loop allowance, quantity, temperature, jacket, label, packaging, destination, and required acceptance tests.

How should the cable be accepted on arrival?

Verify the label and ordered part number, inspect the cable and latches, connect to the intended hosts, confirm link state and lane mode, then run the site-defined traffic or BER acceptance procedure.
