SUNNYVALE, Calif. , May 27 /PRNewswire/ — Fujitsu Microelectronics America, Inc. (FMA) today issued a technical paper entitled “The Fujitsu 56GSa/s Analog-to-Digital Converter Enables 100GbE Transport,” describing the technology challenges involved in creating a long-haul 100Gbps optical transport network, and the enabling technology developed by Fujitsu for 100Gbps Ethernet and OTU-4 transport systems using coherent receivers.
The paper also describes the forces pushing towards a single-chip CMOS solution for a 100Gbps coherent receiver with four 56GSa/s Analog-to-Digital Converters (ADCs) and a tera-OPS DSP that dissipates tens of watts. The paper concludes with details on Fujitsu's revolutionary CHArge-mode Interleaved Sampler technology (CHAIS), which allows the implementation of extremely fast, high-resolution ADCs in CMOS process technology. This advanced, innovative solution makes it possible to meet the performance and power requirements of long-haul optical systems.
