Keep high-bandwidth fabric links stable across longer spans with this 800GBASE-FR8 OSFP transceiver from Axiom. Designed for InfiniBand NDR environments, it supports 800 Gb/s signaling over single-mode fiber with a dual LC interface and 4xCWDM optical architecture. The 2 km reach makes it a strong fit for data center interconnects, spine-to-leaf extensions, and clustered compute environments where short-reach optics are not enough. The finned-top OSFP form factor is built for thermal performance in dense switch platforms, helping maintain optical reliability under sustained load. For teams standardizing on high-port-density infrastructure, this module delivers the reach, speed, and connector simplicity needed to reduce cabling complexity without compromising performance. It is a practical choice when the cost of a link failure or a reach limitation is higher than the premium for the right optic. Use it where InfiniBand NDR fabrics need predictable optical performance over single-mode fiber and where deployment density demands a compact, high-speed transceiver with the right thermal profile.
