摘要： In a receiver, a skew detector detects a skew between two synchronization symbols having different wavelengths among synchronization symbols included in received signals. A skew rough adjustment calculator calculates a delay compensation amount for each received signal based on the skew and a signal delay characteristic in a transmission path. A variable delay processor deskews the received signals based on the delay compensation amount.
