摘要/Abstract

摘要：

In optical coherent receivers, the timing error detector (TED) in synchronization loop can not work normally when signal is distorted by large dispersion. This paper proposes a novel clock synchronization scheme which adds a butterfly-structured adaptive equalizer to the loop to fulfill synchronizations, equalizations and polarization de-multiplexing of two polarization states simultaneously under the control of single voltage-controlled oscillator (VCO). Simulink simulation demonstrates the rationality and the feasibility of the combined loop with single VCO.
