What is Multimode Optical Fiber? The Foundation of Local Networks

Multimode Optical Fiber is a type of fiber optic cable. It's designed to carry multiple light modes or signals at the same time. This is different from single-mode fiber, which carries only one light signal. Multimode fiber has a larger core. This larger core allows multiple light rays to travel down the fiber at once. It's the foundation of most local and campus networks.

Why is it so widely used?

• Cost-Effectiveness: Multimode fiber is much more affordable than single-mode fiber. The components used to connect it, like transceivers and connectors, are also significantly cheaper. A study by the Fiber Optic Association found that a 100-meter multimode fiber installation can be 70% less expensive than a comparable single-mode installation.

• Ease of Installation: The larger core size makes it easier to install. It is less sensitive to bends and misalignments. This reduces installation time and labor costs.

• High Bandwidth for Short Distances: For short distances (up to 550 meters), multimode fiber provides a very high bandwidth. It can support speeds of up to 100 Gbps. This is more than enough for most local area networks (LANs) and data centers.

In short, multimode optical fiber is a smart choice for short-distance applications. It's a cost-effective, easy-to-install, and high-performance solution.
