Abstract A simple and stable loop consisting of a pair of concatenated electroabsorption modulators (EAMs) and 10 GHz clock recovery module is presented and demonstrated experimentally for simultaneous demultiplexing and clock recovery for OTDM networks. The 10Gb/s demultiplexed signal and 10GHz recovered clock are successfully implemented from 80Gbit/s and 160Gbit/s OTDM signals utilizing the loop. The loop based on EAM-PLL can provide excellent tolerance range (>5dB) of the OSCR of the source laser, and the recovered clock signal exhibits low rms jitter over a dynamic input optical power range of 15dB.
