The design uses physical dimensions that exceed the size of QSFP-DD, which measures 18.35 \u00d7 89.4 \u00d7 8.5 millimeters, to solve thermal problems that occur during 800G transmission.<\/p>\n\n\n\n<p>Key technical specifications include:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Specification<\/strong><strong><\/strong><\/td><td><strong>Details<\/strong><strong><\/strong><\/td><\/tr><tr><td><strong>Data Rate<\/strong><\/td><td>800 Gbps (8 \u00d7 106.25 Gbps lanes)<\/td><\/tr><tr><td><strong>Electrical Interface<\/strong><\/td><td>800GAUI-8<\/td><\/tr><tr><td><strong>Modulation<\/strong><\/td><td>PAM4 (53 Gbaud)<\/td><\/tr><tr><td><strong>Power Supply<\/strong><\/td><td>3.3V single rail<\/td><\/tr><tr><td><strong>Management Interface<\/strong><\/td><td>CMIS 5.0\/5.1<\/td><\/tr><tr><td><strong>Operating Temperature<\/strong><\/td><td>0\u00b0C to 70\u00b0C (commercial grade)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The OSFP MSA (Multi-Source Agreement) establishes the mechanical and electrical and thermal requirements which enable different manufacturers&#8217; modules to work together. The 800GBASE Ethernet implementations of IEEE 802.3ck standards provide performance standards which all industry players must follow.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_OSFP_for_800G\"><\/span><strong>Why OSFP for 800G?<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The transition from 400G to 800G optical modules presents significant engineering challenges which engineers must solve through their work on power dissipation and thermal management problems. The 800G optical transceiver needs between 15 and 20 watts of power which means it requires almost twice as much energy as the 400G module. The larger OSFP form factor provides approximately 30% more surface area for heat dissipation compared to QSFP-DD, enabling reliable operation at these higher power levels.<\/p>\n\n\n\n<p>This thermal advantage becomes critical in dense switch configurations. A fully populated 32-port 800G switch generates approximately 480\u2013640 watts from optics alone, plus an additional 300\u2013400 watts from the switch ASIC. The OSFP form factor enables data center operators to handle their challenging thermal loads through its advanced thermal design, which eliminates the need for complex cooling systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"800G_OSFP_Types_and_Specifications\"><\/span><strong>800G OSFP Types and Specifications<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The 800G OSFP transceivers operate according to three different criteria, which include their transmission distance, fiber type, and optical technology.
