800G OSFP

800G OSFP transceivers represent the current state of the art for AI / ML training clusters and next-generation datacenter cores. The OSFP form factor (slightly larger than QSFP-DD) carries 8 lanes of 100G PAM4 with improved thermal headroom — important at 800G's ~16-20 W power envelope. Optiunik manufactures OSFP modules across DR8 (500 m / SMF via MPO-16), 2× DR4 (2× 500 m breakout to 2× 400G), 2× FR4 (2× 2 km), 2× LR4 (2× 10 km), and emerging ZR variants. Modules are programmed for Nvidia Quantum-2 / Spectrum-X, Cisco Silicon One, Arista 7800R, and Mellanox MLNX-OS coding. CMIS 5.0+ compliant firmware, full DDM / I²C diagnostics, and integrated finned heatsinks.
