Q
If an Optical Carrier is represented as OC-n, generally the link speed equals(in Mbps) __________
AA. N*39.8
BB. N*51.8
CC. 2n*51.8
DD. None of the mentioned
Correct Answer:
B. B. N*51.8
Explanation:
The base unit of transmission rates in optical fibre is 51.8 Mbits/s. So an optical carrier represented as OC-n has n*51.8 Mbits/s transmission speed. For eg. OC-3 has 3*51.8 Mbits/s speed.
