Abstract
The authors study the coexistence of quantum entanglement with fiber optical communication at the telecom $C$ band. The performance of quantum key distribution based on distributed energy-time entanglement coexisting with classical light is characterized, which paves the way for developing a cost-effective quantum entanglement network compatible with fiber communications.
