Door-to-door optical modulator QSFP-DD

Home / Door-to-door optical modulator QSFP-DD

QSFP-DD (Quad Small Form Factor Pluggable Double Density) is an evolution of the QSFP family, extending its lane capacity from 4 to 8 high-speed electrical lanes. Each lane supports up to 50G PAM4 signaling, delivering an aggregate throughput of 400G — or even 800G in advanced PAM4. Cisco ® QSFP-DD and OSFP 800G ZR/ZR+ coherent optics modules enable 800G traffic over.
