Long-distance variants, typically referred to as LX, EX, ZX, or ER/LR SFPs, are engineered with higher optical power budgets and longer wavelength lasers (e., 1310nm, 1550nm), enabling transmission distances from 10 km up to 80 km or more over single-mode fiber (SMF). Perfect for expansive spaces like large buildings, ensuring clear, high-quality visuals. ● Unmatched Stability with Fiber Optic: Our. The Cisco 400G QSFP-DD Ultra Long-Haul Coherent Optics Module enables 400G traffic anywhere over dense wavelength division multiplexing amplified networks, and is available in both C-band and L-band. This NanoSpeedTM switch family features ultra-low loss (<1dB), polarization independence, bi-directional, covering wavelength from 500nm to 2000nm, high optical power handling. ● Up to 550M Transmission Range: Enjoy zero-latency, 4K ultra HD HDMI signal transmission over a distance of up to 550m (1800ft) using multi-mode optical fiber cable.
