Broadcom Corp. has revealed that its high performance 20nm signal processing enhanced mixed signal technologies have enabled NTT Electronics' NLD0640 100G coherent digital signal processor (DSP). Touted by the company as an industry first, the device is optimised for 100G-and-beyond optical fibre communication systems. The Broadcom-enabled coherent physical layer transceiver (PHY) consumes less than half the power of existing long-haul coherent ICs and expands the use of coherent technology to metro and shorter reach links.

Designed in collaboration with NTT Electronics (NEL), the low-power 100G coherent 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. Featuring Broadcom's best-in-class 65GS/s 8bit ADC and DAC IP with advanced features such as digital signal enhanced performance, NEL's 100G coherent PHY optimises power and performance in both long-haul and metro applications.

According to industry analyst firm Infonetics Research, the demand for 100G optical transceivers is growing rapidly as carriers aggressively roll out the latest technology. Infonetics predicts that over the next few years, short and intermediate metro reach interfaces will make up a larger proportion of revenue as the technology moves from service provider to much higher volume data centre and enterprise applications.

The exponential increase in design complexity in today's SoC solutions combined with product differentiation and time-to-market pressures has led OEM manufacturers to rely on Broadcom's custom IC services. Leveraging one of the most extensive networking, mixed signal and high speed interface IP portfolios and proven time-tested design methodology, Broadcom provides a more reliable path to production, thus avoiding costly multiple chip spins and/or schedule delays.

The NLD0640 100G coherent DSP is now available from NTT Electronics.
