In optical fiber technology, multimode fiber is optical fiber that is designed to carry multiple light rays or modes concurrently, each at a slightly different reflection angle within the optical fiber core. ... Multimode fiber has a larger core than single mode.
SIngle-mode fiber optic cable excels at long-distance communication. Single-mode cable is designed to carry a single signal source with low transmission loss over great distances. It is frequently used for communication systems due to the clarity it provides. This type of fiber optic cable has the smallest core and the thickest sheathing.
Multimode cables are designed to carry multiple signals, however, this capacity comes with a loss of range. Multimode cables come in two primary varieties. What are the different types of multimode fiber optic cables? Your choices are step index or graded index cables.
Step index multimode cables have a thick core through which signals are fed. They work well over moderate distances and can offer longer range communication potential with the use of amplifiers. The various light signals enter at different angles, transmitting at different rates through the cable.
