The definitive guide to the QSFP optical module series (40G, 100G, 200G, 400G, 800G). Compare 400G/800G optics, understand , QSFP, QSFP28, and QSFP-DD is not just a speed decision. Ent, QSFP, QSFP28, and QSFP-DD is. QSFP (Quad Small Form-Factor Pluggable) optical modules emerged to meet this demand, becoming a pivotal technology for data center interconnects due to their compact size and exceptional performance. From the initial 40G to today's 800G, the QSFP family has continuously evolved, driving the. We provide an industrial-grade reference framework, complying with the latest MSA (Multi-Source Agreement) updates, including SFF-8679 Rev 1. 4 (Jan 2025), to help you design robust, scalable optical fabrics. The Master Reference Matrix: SFP vs. When new-generation form factors are available, you'll be able to reuse the first generation and transition gradually. It will also allow you to upgrade to 400G. Broadcom's Optical Module PHY portfolio spans multiple technology nodes — 16nm, 7nm and now 5nm, with data rates from 100 Gbs to 1. Comprising five flagship platforms, Centenario, Jesko, Portofino, Gemera, and Cygnus, Broadcom's DSP PAM-4 portfolio covers 100G, 400G, 800G, and 1.
