➤ Why Distance (10KM LR) and Fiber Type (Single-Mode) Matter?
10KM Reach (LR - Long Reach): Bridges gaps between buildings, across campuses, or to nearby data centers without expensive intermediate equipment, solving the distance limitations of copper (DAC cables) or shorter-reach optics (like 10GBASE-SR for multi-mode fiber).
Single-Mode Fiber (SMF): Offers significantly lower signal attenuation and dispersion compared to Multi-Mode Fiber (MMF), enabling much longer transmission distances (like 10km, 20km, 40km, 80km) and higher bandwidth potential. It's the standard for metropolitan area networks (MANs), telecom infrastructure, and long-reach data center links.
