Employing a differential detection scheme, excellent locking stability is achieved. The recovered clock signal allows error-free 160 Gbit/s transmission.en621384160 Gbit/s clock recovery with electro-optical PLL using bidirectionally operated electroabsorption modulator as phase comparatorjournal article
