On a data network, Ping measures the round-trip time of messages. Ping at long distance is limited by data transfer at the finite speed of light. A telecom cable has a length of 30,000 km. The glass fiber has a refractive index of 1.5. Find the minimum Ping in second if data go through this whole cable length and come back (round-trip). T
