How Does Single-Mode Fiber Compare to Multi-Mode Fiber?
Single-mode fiber (SMF) offers distinct advantages over multi-mode fiber (MMF), particularly in its core diameter and chromatic dispersion performance. While SMF typically features a core diameter of 8-10µm, MMF ranges from 50 to 125µm. More importantly, SMF exhibits significantly lower chromatic dispersion at higher wavelengths, which is essential for modern optical communication systems operating in the O-band and L-band. Research indicates that SMF achieves up to a 40% reduction in chromatic dispersion in the O-band and 25% in the L-band when transmitting data rates of 400G and beyond. This leads to longer transmission distances, reduced bit error rates, and less frequent regeneration needs—ultimately resulting in substantial cost savings for long-haul applications and data center interconnects.
