The number of gold fingers on the electrical ports of QSFP-DD is twice that of QSFP28. In addition, this packaging method uses <a href=\"https:\/\/mvslinks.com\/fr\/news\/blog\/understanding-pam4-enhancing-data-transmission-efficiency\/\">PAM4<\/a> technology (4 Pulse Amplitude Modulation), which is sufficient to support rates up to 400Gbps.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"800G_OSFP\"><\/span><strong>800G OSFP:<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>OSFP package (full name Octal Small Form Factor Pluggable), the &#8220;O&#8221; stands for &#8220;octal&#8221;, meaning the use of eight electrical channels to achieve 400G, the size is slightly larger than QSFP-DD, with higher wattage. When considering optical modules for high-speed data transmission, it&#8217;s essential to evaluate their bandwidth capabilities and thermal performance. OSFP modules, for instance, are designed as 8-channels to support up to 800G of total throughput, resulting in higher bandwidth density. Furthermore, DD, with its higher wattage optical engine and transceiver, and featuring an integrated heat sink, exhibits slightly better thermal performance, making it a suitable choice for demanding data center environments.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Advantages_of_different_packages_of_800G_optical_modules\"><\/span><strong>Advantages of different packages of 800G optical modules<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"800G_QSFP-DD-2\"><\/span><strong>800G QSFP-DD:<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>It can be downward compatible with other packages, compatible with QSFP+(Quad Small Form-factor Pluggable Plus)\/QSFP28(Quad Small Form-factor Pluggable Plus 28)\/QSFP56(Quad Small Form-factor Pluggable 56)\/QSFP(Quad Small Form-factor Pluggable) packages. 2.<\/li>\n<li>The design of 2&#215;1 stacked integrated cages and connectors enables their use in both single-height and dual-height cage connector systems.<\/li>\n<li>With SMT connectors and 1xN cages, the cage design and optical module enclosure is optimized to achieve a thermal capacity of at least 12W per module.
