Popular variants include 40GBASE-SR4, capable of up to 100 m over OM3 and 150 m over OM4 multimode fiber, as well as QSFP BiDi models that enable plug-and-play migration over existing duplex MMF infrastructure. For higher-density needs, 100GBASE LR4, SR10, PSM4, and DR/FR options offer flexible single/multi-mode choices across shorter or extended distances. For future-ready deployments, QSFP-DD modules support next-gen performance up to 400G and 800G while maintaining backward compatibility and optimized thermal management.

QSFP modules feature a hot-swappable design and digital optical monitoring (DOM), ensuring quick installation, real-time diagnostics, and reliable performance. Their high-density, low-power design helps maximize port capabilities in rack and edge environments—delivering efficiency without compromising throughput.
