What are the two most common multimode optical fiber types?

The two most common multimode optical fiber types are indeed characterized by their core and cladding diameters, which are expressed in micrometers (μm). In this case, 62.5/125 μm and 50/125 μm fibers are standard specifications in the industry and are frequently used for various applications in multimode fiber optic communication.

The 62.5/125 μm fiber has a core diameter of 62.5 micrometers and a cladding diameter of 125 micrometers. This type of fiber originally gained popularity for its compatibility with LED light sources and is widely used in premises and data center applications. It provides decent performance for short-distance data transmission.

On the other hand, the 50/125 μm multimode fiber is designed for higher bandwidth and distance capabilities. It can support laser light sources and is often utilized for high-speed data networks, allowing for improvements in data transmission rates over longer distances compared to 62.5/125 μm.

The combination of these two fiber types provides a broad capability for various networking needs, making them the most common in the field of multimode optical fiber. Their unique specifications allow them to effectively address different performance requirements in fiber optic installations, establishing their
