20nm 100G PHY is claimed to be a world first

The PHY allows the use of a DSP within lower power and smaller second generation coherent 100G modules, including C form factor pluggable (CFP) and compact CFP2 analogue coherent optical (ACO) modules. The PHY features 65GS/s 8-bit ADC and DAC IP, making it suitable for both long-haul and metro applications.

According to Infonetics Research, the demand for 100G optical transceivers is growing. As the technology moves from service provider to data centre and enterprise applications, Infonetics predicts short and intermediate metro reach interfaces will make up a larger proportion of revenue.

"Our collaboration with NTT Electronics has resulted in a game-changing product optimised to deliver the economies of scale and flexibility needed for wide-scale adoption and rapid deployment of 100G over fibre optic networks," said Lorenzo Longo, Vice President and General Manager, Physical Layer Products, Broadcom. "Our industry leading 20nm signal processing enhanced mixed-signal technologies and A0 silicon execution has allowed NTT Electronics to substantially reduce power consumption while meeting stringent time to market requirements."

"We are strongly committed to pioneering innovation in the coherent DSP market through our robust partnership with Broadcom," said Haruhiko Ichino, NTT Electronics Executive Vice President and General Manager of Broadband System & Device Business Group. "Our novel LP-DSP has already been shipped to more than ten customers, who are designing their product families. We look forward to deployment of our product in early 2015 thereby providing value to the end customers by maximising the number of 100G ports per system."
