Which risk increases when symbol timing recovery fails in coherent optical communication?

💡 Explanation

Bit error rate grows because inaccurate sampling instants lead to incorrect data interpretation, resulting from the *clock recovery process* experiencing instability. Therefore, the received data is misinterpreted, rather than phase noise or power being directly compromised, under ideal circumstances.
