Commercial overview

A focused 400G OSFP route for buyers who already know the host

400G OSFP optics are selected around a specific platform, not as a generic substitute for QSFP-DD or QSFP112. The mechanical top, cage cooling, electrical mode and optical scheme must agree with the host and the far-end path. PhotonVerge uses this collection to separate approved 400G OSFP optical families from cables and other packages. A useful RFQ names the host, software, port configuration, thermal requirement, peer optic, fiber interface, reach, quantity and destination.

Use this collection for an identified 400G OSFP cage

Good starting point

  • OSFP-based 400G switch or adapter ports
  • InfiniBand or Ethernet projects with a documented platform requirement
  • buyers comparing short parallel, multimode and duplex-fiber options
  • part-number cross-reference requests that permit compatible alternatives

Start elsewhere when

  • QSFP-DD or QSFP112 host ports
  • fixed AOC or copper cable assemblies
  • requests that do not identify the thermal top or remote endpoint

Engineering boundary

The OSFP shell does not settle thermal or protocol compatibility

Confirm the host cage, top construction, network mode, software and coding target before treating a module as host-compatible. Then confirm the optical PMD, connector, FEC and peer optic as a separate link review. Final acceptance should come from the intended host and traffic profile.

  • Host and port
  • Finned or flat top
  • Software and port mode
  • Optical PMD and connector
  • Peer optic and FEC
  • Sample acceptance and document requirements

Application planning

Typical 400G OSFP project contexts

The platform and topology determine whether this collection is appropriate.

HPC clusters

Repeatable fabric links with controlled coding and sample acceptance.

Lab validation

Host and peer combinations that require a documented test matrix.

Shortlist the link before requesting price

Share both endpoints, the physical path and quantity so the quotation can identify an exact SKU and unresolved risks.

Prepare a technical RFQ

Supply coordination

Resolve platform fit before the 400G OSFP quotation

The workflow keeps cable products and other form factors out of the shortlist.

1. Validate the OSFP host

Record platform, port, software and thermal top.

2. Map the link

Identify PMD, connector, fiber, peer and reach.

3. Review coding

Confirm target identity, FEC and monitoring fields.

4. Select the SKU

Return an exact candidate and open technical questions.

5. Run sample approval

Test in the intended topology with recorded criteria.

6. Set commercial terms

Confirm quantity, destination, schedule, warranty and documents.

Buyer questions

Frequently asked questions about 400G OSFP Transceivers

Why must a 400G OSFP RFQ specify finned top or flat top?

The top construction relates to how the host removes module heat. A product can have the correct speed and optical scheme yet be mechanically or thermally unsuitable for the cage. Use the host platform documentation and include the required construction in the exact SKU. Validate temperature behavior under representative traffic and ambient conditions before rollout.

Can a 400G OSFP optical module replace a 400G OSFP DAC?

No direct substitution should be assumed. A pluggable optical link also requires the correct fiber path and a compatible optic at the peer end, while a DAC is a fixed copper assembly with its own length and host limitations. Compare topology, reach, power, serviceability and both endpoints before changing media.

How are DR4 and FR4 different in a 400G OSFP project?

DR4 uses a parallel single-mode path, while FR4 uses multiplexed wavelengths over duplex single-mode fiber. This changes connector type, fiber count, lane mapping, peer optic and sometimes the reason for choosing the link. Verify the installed fiber plant, route loss, FEC and exact host support before comparing candidates.

What proves a 400G OSFP compatible module is acceptable?

Use a record that combines host recognition, required identification fields, stable traffic, diagnostic data, temperature observation, FEC counters and optical interoperability with the intended peer. Identify the exact SKU, serials, host software and port configuration. A vendor code or successful insertion alone is not a complete approval result.

Does the collection page show live 400G OSFP inventory?

No. It identifies candidate product families. Live availability and delivery commitments require the exact SKU, coding target, quantity, document scope, destination and requested schedule. The commercial response should also state warranty, shipping basis and any assumptions instead of treating catalog presence as a stock promise.

Procurement guide

Buying 400G OSFP as a platform-specific component

Confirm the host before the optics

The port and thermal design determine whether 400G OSFP is the correct collection. Capture platform, software, cage, top construction and configured mode before looking at optical families.

Select the path

Choose DR4, FR4 or SR8 from the installed fiber and peer requirement. Connector and nominal reach are not enough; document lane mapping, polarity, FEC and loss.

Resolve coding and monitoring

State the required vendor identity, diagnostic fields, alarms and labels. These requirements should be tied to the exact SKU and kept separate from optical interoperability.

Approve a repeatable sample

Use the real host and peer, frozen software and measurable traffic criteria. Retain the result with serial information before quantity price, schedule and warranty are finalized.
