Various factors, including core diameter, cable length, and transceiver compatibility, influence the cost of fiber optic cabling. In general, single-mode fiber is slightly more expensive than multimode fiber due to its more complex manufacturing process and higher-cost. Single mode fiber optics are more expensive than multimode fiber because they are designed to carry a single ray of light without any dispersion, meaning they can transmit data over longer distances with very low signal degradation. This precision and ability to carry light over longer distances. Due to its single-light mode, single-mode fiber offers superior bandwidth capabilities compared to multimode fiber. While still capable of carrying. OS2 and OM4 are the most common types in modern network installations due to their balance of performance and cost. This precision requires lasers as light sources, which are more expensive but deliver high-intensity, narrowly focused beams.
