Final answer:
The color of 62.5/125 OM1 multimode fiber is typically orange, used to distinguish it from other types of multimode fibers.
Step-by-step explanation:
The color of the 62.5/125 OM1 legacy multimode fiber is generally orange. This color coding is used to distinguish the OM1 type of multimode fiber from other types such as OM2, OM3, and OM4, which have different bandwidth and distance characteristics and are typically color-coded orange, aqua, and aqua or yellow, respectively. It is important to use the correct color when working with optical fiber to ensure compatibility and performance of the network.
