Abstract:We compare three feedforward non-data-aided clock recovery algorithms suitable for burst-mode reception in PONs and datacenters. Our experimental setup allows real-time OOK transmission at 3 Gbit/s. The tolerable clock frequency mismatch is 475 ppm.
We demonstrate and evaluate a fully-blind digital signal processing (DSP) chain for 100G passive optical networks (PONs), and analyze different equalizer topologies based on neural networks with low hardware complexity.

We compare digital non-data-aided feedback and feedforward clock recoveries for burst-mode operation in high-speed PONs. For 56 GBd NRZ, PAM2, and PAM4, we demonstrate that a clock frequency offset of 20 ppm can be synchronized within 40.96 ns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
