Final answer:
The 50/125 OM3 and OM4 fiber optic cables are both color-coded with an aqua jacket, which distinguishes them from other types of optical fibers like OM1 and OM2 which usually have an orange jacket.
Step-by-step explanation:
The color of 50/125 OM3 and OM4 fiber optic cables, commonly used for high-speed data transmission and laser-optimized multimode applications, is aqua. OM3 and OM4 are classifications of multimode optical fiber that are designed to carry multiple light signals at once, with OM4 being an improved version with greater bandwidth and longer reach than OM3.
Both types of cables are typically color-coded with an aqua jacket to distinguish them from other types of optical fiber cables such as OM1 and OM2, which often have an orange jacket.
