Specifications, compatibility and ordering information
The 800G OSFP 2×FR4 optical transceiver is designed for 800G links that need to extend beyond the 500m parallel-optics range while remaining within a 2km single-mode data center connection. It combines two FR4 optical paths in one OSFP module and uses dual duplex LC fiber interfaces. This makes it a different deployment choice from MPO-based DR8 or 2×DR4 modules: the purchasing decision is not simply “800G OSFP,” but whether the approved network design specifically calls for a 2×FR4, LC-based 2km optical link.
ETU-Link lists the 800G OSFP 2×FR4 as a CWDM4-based 2km solution for high-speed interconnection between switches and between GPU servers and switches in AI data centers. Within the 800G optical transceiver range, this gives procurement teams a longer-reach option without moving directly to a 10km-class module. Before issuing a volume PO, buyers should match the required reach, host platform, LC fiber infrastructure and intended breakout or port architecture. Where compatibility coding or platform-specific programming is required, that requirement should also be agreed as part of the order rather than assumed from the OSFP form factor alone.
The commercial specification should stay consistent with the approved technical configuration. Order quantity, module identification, labeling, packaging, required documentation, payment terms and delivery arrangement should be confirmed before the order is released. This is particularly important on projects using several 800G optical types at the same site, because an OSFP housing can look similar while the optical interface and link design are different. When the shipment arrives, the product designation, dual LC interfaces, 2km rating, quantity, labels and any agreed compatibility configuration should be checked against the approved PO before the modules are introduced into the production network.
800G OSFP 2×FR4 Specifications
The specifications below cover the main product characteristics that define the 2×FR4 link and should be matched with the host equipment and installed fiber path before procurement approval.
| Specification | Value |
|---|---|
| Data Rate | 800G |
| Form Factor | OSFP |
| Optical Type | 2×FR4 |
| Optical Architecture | Two FR4 Optical Paths |
| WDM Type | CWDM4 |
| Transmission Distance | Up to 2km |
| Fiber Type | Single-Mode Fiber |
| Optical Interface | Dual Duplex LC |
For project sourcing, the 2×FR4 designation, 2km link requirement and dual-LC fiber architecture should remain unchanged from technical approval through quotation and delivery. Buyers should avoid substituting an MPO-based 800G module simply because the data rate and OSFP form factor are the same. Final compatibility requirements, order quantity and commercial terms should be recorded with the PO, while incoming inspection should confirm that the delivered modules match the approved optical type and interface before deployment.
