40Gb/s System-on-Chip (SoC) for coherent optical networking from PMC-Sierra

PMC-Sierra, Inc. has announced the 40Gb/s System-on-Chip (SoC) solution for coherent optical networking. PMC-Sierra claims the PM6373 POLO 40G doubles line card density and reduces power consumption by more than 50 percent when compared to 40G non-coherent network deployments. PMC-Sierra says its unique combination of high-performance mixed-signal, digital signal processing (DSP), analogue to digital convertor (ADC), OTN framing and Swizzle Forward Error Correction (FEC) SoC architecture digitally compensates for optical impairments and improves optical performance by more than 2dB for an additional 25 percent fiber reach extension, which dramatically lowers the cost of transmission.

"Carriers are choosing coherent deployments because it is the most effective technology to increase fiber transmission rates and build all-optical networks," said Andrew Schmitt, directing analyst of Optical at Infonetics Research. "Coherent technology is one of the fundamental technologies of what I call the Optical Reboot: the optical network architecture transformation that will take place this decade."

PMC-Sierra's POLO 40G eliminates widely deployed optical equipment such as dispersion compensation management (DCM), dispersion compensated fiber (DCF), and hands-on operational cost of tuning and managing this equipment so that OEM line cards can transit from today's two- or three-slot implementations to single-slot. Line card tuneable dispersion compensators (TCMs) are no longer required.

"With the explosion of bandwidth demand driving the need to upgrade existing metro, regional and longhaul fiber infrastructures to 40Gb/s and beyond, POLO 40G will be a key enabler to make the optical buildout a reality," said Daryn Lau, vice president and general manager of PMC-Sierra's Communication Products Division. "PMC-Sierra has significant experience in delivering innovative products to enable evolving Carrier network requirements. Our POLO 40G is uniquely positioned to provide the combination of bandwidth per unit, power and cost when compared to existing multi-slot coherent solutions even in cost-sensitive Carrier Ethernet service point-to-point and metro deployments."

POLO 40G is a single chip CMOS coherent DP-(D)QPSK transmission transceiver that delivers the full set of compensation capabilities, including chromatic dispersion (CD), polarization mode dispersion (PMD), second order PMD (SOP), and high-rate polarization tracking, among others. The platform provides an SFI 5.1 client interface and a fully OIF-compliant line side DP-(D)QPSK interface that seamlessly integrate into MSA optical modules and onto a line card with next-generation CFP2 optical modules. POLO 40G also incorporates flash ADC technology with background calibration to maintain operating performance in demanding Carrier environments.

Full Bit Transparent Operation: Supports all FEC overhead rates between seven percent and 20 percent and backward compatible with legacy 40Gb/s coherent solutions.
Blind Equalization and Interoperability: Utilizes ITU standard OTL3.4 encoding/decoding for polarization resolve and ITU standard G.709 FEC to drive broad industry interoperability.
Extended Reach with High Gain 18.8 Percent FEC Option: +2dB additional OSNR margin provides an additional 25 percent reach extension over all other seven percent enhanced FEC implementations.
Increased Spectral Efficiency: 40Gb/s DP-(D)QPSK is ready made for future 25GHz ITU grid spacing that doubles spectral efficiency from 0.8Bit/s/Hz to 1.6Bit/s/Hz.

White Paper from PMC-Sierra titled "The Era of Coherent Optical Networking" provides an overview of coherent optical technology and the critical power, cost, and optical challenges it solves to enable Carriers to deliver a tidal wave of high-capacity services with much lower capital and operational costs. The paper is available for download at www.pmc-sierra.com/wireline (registration required).

Availability: PMC-Sierra's PM6373 POLO 40G will sample later this year for sponsor customers. The device is implemented in 40nm CMOS technology and packaged in a 480-pin 23mm x 23mm FCBGA package.
