Compared with today&#8217;s 200Gb\/s-per-lane pluggables, USFP delivers&nbsp;<strong>4x the bandwidth and front-panel bandwidth density<\/strong>&nbsp;at roughly&nbsp;<strong>1.3x the power efficiency<\/strong>, letting AI factory operators scale compute inside the same network footprint while shrinking networking&#8217;s share of the total power budget.<\/p>\n\n\n\n<p>USFP (Ultra-Dense Small Form Factor Pluggable) is a new optical module form factor from NVIDIA and Cisco. It packs 16 full-duplex lanes at 400Gb\/s each into an OSFP-sized package \u2014 6.4Tb\/s today, scaling to 32 lanes and 12.8Tb\/s. It targets Ethernet AI fabrics, supports both switches and SuperNICs, dissipates up to 100W without an embedded cooling circuit, and is being developed toward an open multi-source

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>AI models keep growing and inference demand keeps expanding, which means AI factories must connect far more compute \u2014 while managing network complexity, power draw and cost. Moving more data per watt and per switch is how operators improve the return on their infrastructure investment.<\/p>\n\n\n\n<p>Scaling an AI fabric requires two things at once: more bandwidth per connection, and more connections per switch. The constraint is physical. When a switch runs out of ports, the next option is adding another switch tier plus more optical links \u2014 which increases latency, power consumption and cost.<\/p>\n\n\n\n<p>USFP is designed to move AI builders from 200Gb\/s-per-lane to 400Gb\/s-per-lane Ethernet fabrics without adding network tiers, while preserving the pluggable operating model that has already been proven across multiple generations of data center networks. The goal: adopt next-generation optics without ripping out existing infrastructure.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2026\/10\/ultra-dense-small-form-factor-pluggable-1024x576.jpg\" alt=\"ultra-dense-small-form-factor-pluggable\" class=\"wp-image-20486\" style=\"width:800px\" srcset=\"https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2026\/10\/ultra-dense-small-form-factor-pluggable-1024x576.jpg 1024w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2026\/10\/ultra-dense-small-form-factor-pluggable-300x169.jpg 300w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2026\/10\/ultra-dense-small-form-factor-pluggable-768x432.jpg 768w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2026\/10\/ultra-dense-small-form-factor-pluggable-1536x864.jpg 1536w, https:\/\/www.fibermall.com\/blog\/wp-content\/uploads\/2026\/10\/ultra-dense-small-form-factor-pluggable.jpg 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"USFP_specifications_at_a_glance\"><\/span><strong>USFP specifications at a glance<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\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>USFP<\/strong><strong><\/strong><\/td><td><strong>200G\/lane pluggable (baseline)<\/strong><strong><\/strong><\/td><\/tr><tr><td>Electrical lane rate<\/td><td>400Gb\/s<\/td><td>200Gb\/s<\/td><\/tr><tr><td>Lane count (initial configuration)<\/td><td>16 full-duplex<\/td><td>8<\/td><\/tr><tr><td>Total capacity<\/td><td>6.4Tb\/s (x16) \u2192 12.8Tb\/s (x32)<\/td><td>\u2014<\/td><\/tr><tr><td>Package size<\/td><td>OSFP-sized footprint<\/td><td>OSFP<\/td><\/tr><tr><td>Bandwidth \/ front-panel density<\/td><td>4x<\/td><td>1x (baseline)<\/td><\/tr><tr><td>Power efficiency (per bit)<\/td><td>~1.3x better<\/td><td>Baseline<\/td><\/tr><tr><td>Max module power dissipation<\/td><td>Up to 100W, no embedded cooling circuit<\/td><td>\u2014<\/td><\/tr><tr><td>Target endpoints<\/td><td>1.6Tb\/s<\/td><td>\u2014<\/td><\/tr><tr><td>Host devices<\/td><td>Switches and SuperNICs<\/td><td>Switches, NICs<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"16_lanes_today_32_tomorrow_doubling_lane_count_and_lane_rate\"><\/span><strong>16 lanes today, 32 tomorrow: doubling lane count and lane rate<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The first planned USFP-based transceivers will integrate&nbsp;<strong>16 full-duplex lanes inside an OSFP-sized package<\/strong>, supporting both switches and SuperNICs, with a roadmap to&nbsp;<strong>32 lanes and beyond<\/strong>.<\/p>\n\n\n\n<p>By doubling lane count&nbsp;and&nbsp;doubling bandwidth per lane simultaneously, USFP lets AI fabrics connect more 1.6Tb\/s endpoints without adding a switch tier.
