You are designed a link layer protocol for a link with bandwidth of 1 Gbps (109 bits/second) over a fiber link with length of 800 km. Assume the speed of light in this medium is 200000 km/second. What is the propagation delay in this link?
Correct Answer: D
Question 701 Explanation:
Tp=Distance/Time
=800/200000
=4*10-3 sec
= 4 milliseconds
