If the bandwidth of an OC-1 link is 51.84 Mbps, what is the bandwidth of an OC-3 link?
A) 155 Mbps
B) 51.84 Mbps
C) 155.52 Mbps
D) 1.54 Mbps
C
Explanation: Aside from measuring bandwidth in kbps, Mbps, or Gbps, high-speed optical networks often use optical carrier (OC) levels to indicate bandwidth. As a base reference point, the speed of an OC-1 link is 51.84 Mbps. Other OC levels are simply multiples of an OC-1. For example, an OC-3 link has three times the bandwidth of an OC-1 link (that is, 3 * 51.84 Mbps = 155.52 Mbps).
