What is the characteristic of single-mode fiber cabling?

The characteristic of single-mode fiber cabling is its narrow core, which allows light to propagate primarily at a single angle. This design minimizes modal dispersion, which is the spreading of light pulses over distance. As a result, single-mode fiber can support longer distances and higher bandwidths compared to multi-mode fiber, making it ideal for long-haul telecommunication and data transmission applications.

The narrow core typically only allows one mode of light to travel through it, resulting in clearer signals and less signal degradation over long distances. This characteristic is crucial for modern networks that demand high-speed and reliable communication over extensive areas. Therefore, the design of single-mode fiber is specifically optimized for high-performance applications, ensuring that it can maintain signal integrity over longer links.
