What color adapter should be used with 62.5/125 µm multimode optical fiber?

The appropriate color adapter for use with 62.5/125 µm multimode optical fiber is beige. This specific color code is standardized to indicate that the fiber being used operates within the multimode category, specifically for older multimode fibers. The 62.5/125 µm designation refers to the core diameter of the fiber—62.5 microns in diameter with a cladding diameter of 125 microns—and the beige adapter is recognized within the industry for this type of multimode fiber.

Understanding fiber colors is crucial in telecommunications and data networking to ensure compatibility and prevent misconnection between different types of fibers and adapters. For instance, aqua adapters typically indicate the use of laser-optimized multimode fiber (OM3 and OM4), while green adapters are associated with single-mode fibers, and orange can often signify either 50 or 62.5 µm multimode fiber depending on the context. Thus, beige remains the standard for identifying 62.5/125 µm multimode fiber connections.
