Single-Mode vs Multi-Mode Fiber Optic Cables

Sep 26,2025

FONT

The key differences between single-mode (SM) and multi-mode (MM) fiber cables lie in core size, transmission distance, and use cases: 
• Core Size: SM has a tiny core (8-10μm), allowing only one light mode to travel; MM has a larger core (50/62.5μm), supporting multiple light modes.
• Transmission: SM uses laser diodes, enabling long distances (up to 100km) with low signal loss, suitable for telecom backbones or long-haul data links. MM uses LEDs, limiting distance to 2km max, ideal for short-range applications like data centers or campus networks. 
Our company offers both SM and MM fiber cables, tailored to your project’s distance and cost requirements.
