NVIDIA/Mellanox compatible 1.6T OSFP224 FR8 Twin-port 2x 800G FR4 transceiver module supports a max data rate of 1600 Gbps. It enables the fiber link of 2km over single-mode fiber (SMF) with dual duplex LC/UPC connectors. QSFPTEK manufactured 1.6T 2x FR4 OSFP complies with IEEE802.3dj D1p3: 2x800GBASE-FR4 optical interface, IEEE802.3dj D1p3: 2x800GAUI-4 C2M electrical interface, OSFP MSA Specification Rev 5.1 RHS type 2, CMIS Rev 5.3 and EU Directive 2011/65/EU (RoHS compliant). The 1.6T signal is carried over 4 wavelengths at 1271nm, 1291nm, 1311nm, and 1331nm.
DDM (digital diagnostics monitoring) function is supported on the 1.6T fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) modulation, the FR8 OSFP224 achieves 1600 Gigabit Ethernet through 8 channels 200G PAM4.
The 1.6T FR8 OSFP Silicon Photonics module supports both Ethernet and InfiniBand XDR end-to-end system applications. Designed for supercomputing and HPC, this 1.6T OSFP transceiver provides high-speed connectivity for compute and storage infrastructure. OSFP-RHS with flat-top design is used in Quantum-3 liquid-cooled switches.
Take a look at our test program to get the reliable and high-performance optical transceivers.

Transceivers type 1.6T 2FR4 | 2km | Dual Duplex LC/UPC | RHS/Flat Top
We purchased several of these modules for the first phase of an AI infrastructure project. After evaluating their performance, we've decided to use the same model for the next deployment as well. Having a product that's consistent across different batches makes future expansion much easier.

We selected this module to prepare for future network expansion rather than just meet current bandwidth needs. Moving directly to 1.6T reduced the likelihood of another hardware refresh in the near future. So far, it has been a worthwhile investment for our infrastructure roadmap.

We were looking for a higher-capacity option without increasing the number of switch ports, and this 1.6T module fit the requirement well. The twin-port architecture helped simplify our cabling layout, and overall deployment was cleaner than expected. A practical solution for high-bandwidth environments.

The high bandwidth capability was the main reason we selected it, and the dual-port design helped improve rack-level connectivity. The RHS form factor also worked well in our thermal management setup.
