| Q: | What is the difference between Single-Mode and Multi-Mode fiber? | | A: | Single-mode fiber is most commonly used by telephone companies and in data installations as backbone cable. The light in a single-mode cable travels straight down the fiber and does not bounce off the surrounding cladding as it travels. Multi-mode fiber is usually used as horizontal cable and sometimes as back bone. Multi-mode cable allows more than one mode of light to propagate through the cable. | | << Back >> |
