What does 1 STS1 (signal) represent in terms of OC3?

1 STS1 (signal) equals one third of an OC3, reflecting the aggregation structure in SONET networks.

Where is this conversion commonly applied?

It is used in telecommunications, ISP networks, enterprise WAN circuits, and fiber optic backbone infrastructure involving SONET.

Can fractional OC3 values be used directly?

Fractional OC3 values may require multiplexing or demultiplexing equipment because OC3 aggregates three STS1 signals.
