Specifications, compatibility and ordering information
The 800G OSFP DR8 optical transceiver is designed for native 800G parallel single-mode links, using eight 100G PAM4 optical channels at 1310nm with an MPO-16 interface and a transmission reach of up to 500 meters. For buyers evaluating 800G optical transceivers for AI computing clusters, high-density data center fabrics or network expansion projects, the first point to confirm is the link architecture. DR8 provides a single 800G parallel optical path; it should not be selected simply because the required port rate is 800G.
This distinction becomes important when DR8 is compared with 800G OSFP 2×DR4. Both can be specified for 1310nm single-mode transmission over 500m, but 2×DR4 separates the optical link into two independent 400G paths, while DR8 is built around one native 800G path. For project procurement, this affects the host-port design, MPO cabling arrangement and the way the module will be deployed in the network. A purchasing team should therefore confirm the target switch or NIC platform and the actual fiber architecture before approving the module specification.
For a volume order, the technical specification and the commercial order details should be agreed together. Depending on the project, the items that normally need to be confirmed before the purchase order is released include:
DR8 support on the target host platform and any required compatibility or module coding;
MPO-16 interface, 500m reach and OS2 single-mode cabling requirement;
order quantity, labeling, packaging and documentation requirements;
agreed delivery arrangement and payment terms for the order.
Incoming inspection should be based on the approved order rather than the product name alone. Before the shipment is released for installation, buyers can check the model identification, OSFP form factor, MPO interface, rated transmission distance, quantity, labeling and any agreed compatibility configuration against the purchase specification. For larger deployments, confirming a representative module on the target platform before releasing the full batch into production can also help identify configuration or interoperability issues early.
800G OSFP DR8 Specifications
The following specifications cover the main optical and operating parameters that should be matched with the approved network design before the module configuration is finalized.

For bulk sourcing, the most important point is to keep the approved DR8 configuration consistent from quotation through delivery. The host platform, MPO-16 cabling, transmission requirement and any compatibility coding should be defined before the order is confirmed, while quantity, packaging, documentation, payment and delivery conditions should be recorded with the commercial order. On receipt, these agreed items provide the basis for checking that the delivered modules match the version approved for the project.
