NTT Electronics (NEL) announced industry-first 16nm ultra-low power DSP for both 100G QPSK long-haul and 200G 16QAM Metro optical links.
The new 16nm DSP “ExaSPEED 200” consumes under 10W per 100Gbps in its 200G operation mode, doubling the power efficiency compared to the previous generation 20nm 100G Low Power DSP. It leverages 200G DSP core and 16nm CMOS fin-FET mixed-signal technologies that were developed in collaboration with Broadcom .
The new ExaSPEED 200 integrates enhanced forward error correction (EFEC) based on the de facto standard staircase code. The built-in EFEC enhances line-side interoperability up to Metro reach, and accelerates open networking and system hardware disaggregation.
“Large Service Providers are moving towards SDN-based flexible optical transport architecture to dynamically manage, plan, provision, and re-optimize optical networks with substantially reduced cost,” said Haruhiko Ichino, NEL Executive Vice President and General Manager of Broadband System & Device Business Group. “We are strongly committed to pioneering innovation in the coherent DSP in order to meet their expectation in flexible, software configurable optical ‘white box’ elements that are modular, with interoperable subsystems from multiple vendors,” he added.
