    Specifications

    NVIDIA/Mellanox Compatible 800G OSFP 2XDR4 PAM4 Optical Transceiver Module (1310nm, 2km, 2x MTP/MPO-12 Connectors, SMF, 0℃ to +70℃, DDM)

     

    NVIDIA/Mellanox Compatible 800G OSFP 2XDR4 transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 2km over single-mode fiber (SMF) with dual MTP/MPO-12 connectors. The 800 Gigabit Ethernet signal is carried over 1310nm. QSFPTEK manufactured  2x 400GBASE DR4 OSFP complies with IEEE 802.3cu-2021, IEEE 802.3ck-2022, OSFP MSA Specification Rev 5.0, CMIS Rev 5.0. DDM (digital diagnostics monitoring) function is supported on the 800G fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) modulation, the 2x XDR4 OSFP achieves 800 Gigabit Ethernet through 8x 106.25 PAM4 Retimed 8x100GAUI-1 C2M electrical interface. The 800G 2x XDR4 OSFP is widely used for 800 gigabit Ethernet, data centers, and 800G to 2x 400G applications.

      We deployed a batch of these across several long-reach links and appreciated how consistent the optical measurements were. Made acceptance testing much quicker than expected.

      This batch of 2XDR4s was mainly used for internal stress testing and cross-node verification. During continuous high-traffic throughput tests, the link did not exhibit any jitter or abnormal retraining. We also deliberately performed plug-and-play and re-launch tests, and the performance was consistent.

      Our biggest concern was consistency, all units behaved the same during testing, optical readings were within a very narrow range, and deployment went faster than expected. The modules arrived four days after ordering, which helped us stay on schedule. That's something I definitely appreciated.

      Used these for connecting separate GPU clusters across rooms. We pushed pretty heavy traffic through them during testing and didn’t notice retransmissions or weird latency spikes. One thing I’ll give QSFPTEK credit for is consistency — we ordered multiple units and all of them behaved almost identically.

      Signal quality has been very consistent on our 2km SMF links. The module runs stable under heavy AI traffic, and DDM monitoring is accurate and useful for troubleshooting.

      My first impression of the 2XDR4 was its solid build quality. The casing didn't feel cheap, and plugging and unplugging was smooth. The connectors were clean, without any burrs or looseness. The packaging was also neat, giving the overall impression of a reliable, industrial-grade product. Having used QSFPTEK before, this product continues that impression.
