What is one advantage of multi-mode fiber?

One significant advantage of multi-mode fiber is its lower cost for short distances. Multi-mode fiber consists of a larger core diameter which allows multiple light modes to propagate through the fiber. This characteristic is beneficial for short-distance applications, as it can transmit data over reasonable distances without the need for expensive laser technology. Instead, multi-mode fiber typically uses light-emitting diodes (LEDs) as light sources, which are less expensive than the lasers used in single-mode fiber systems.

This makes multi-mode fiber a more economical choice for local area networks (LANs) or within a building where the distances are shorter, typically within a range of about 300 to 400 meters, depending on the specific type of multi-mode fiber used. In contrast, single-mode fiber is designed for longer distances and requires more sophisticated and costly equipment to ensure proper signal transmission.

While multi-mode fiber may have some advantages regarding fragility and ease of handling, these aspects don’t outweigh its financial benefits when applied to short-range settings. Therefore, the lower cost for short distances stands out as a compelling advantage that aligns with the practical applications of multi-mode fiber technology.
