Single-mode cable is known to be a type of glass fiber strand that will only have one mode of transmission. This will have a higher transmission rate as compared to a multimode fiber because it will be able to cover more distance successfully. The core of the multimode fiber is also known to be bigger.

The multimode fiber is being used when you want to connect you to high bandwidth over certain distances. You would need to know which one you will use. You can make a decision based on the distance that you need to cover. For longer distances, the single-mode cable is more ideal. The multimode cable is more ideal for shorter distances that would require higher bandwidths.

Single-mode means the fiber empowers one type of light mode to be disseminated at a time. While multi modesmean the fiber can transmit multiple modes. The difference between single modes and multimode fiber has a higher "light-gathering" ability and simplify connections. Due to the large core size multimode fiber, some affordable sources such as LEDs (light-emitting diodes) and VCSEL's (vertical-cavity surface-emitting lasers).

Single modes often use a laser or laser diodes to produce light injected into the cable. Multimode fiber bandwidth is limited by light mode. Single-mode fiber bandwidth is unlimited. Also, single-mode fiber is suitable for long-distance applications, while a multitude of optical fiber is fashioned for short distances.
