What does converting from Ethernet (gigabit) to OC3 help with?

It helps users compare local network speeds to backbone optical transmission rates and assists in network design involving LAN and wide-area networks.

Is the conversion between Ethernet (gigabit) and OC3 exact in practice?

No, the conversion is based on nominal data rates and does not consider protocol overhead, signaling differences, or network conditions.

Where is OC3 typically used?

OC3 is used in backbone links between ISPs, leased WAN circuits, and aggregating lower-rate circuits over fiber for long-distance and metro networks.
