A dual continuous‐ and burst‐mode clock recovery module utilizing fiber dispersion

Abstract A clock recovery module suitable for both burst‐ and continuous‐mode optical receiver utilizing fiber dispersion is experimentally demonstrated for the first time. The module utilizes the nonlinear characteristics of the received nonreturn‐to‐zero (NRZ) optical signals experiencing the fiber dispersion and the photo‐detection to extract the clock information. Experiments demonstrated its functionality in both operation modes up to 9 Gbps. © 2010 Wiley Periodicals, Inc.
