PMC-Sierra introduced the PM6373 POLO 40G System-on-Chip for coherent optical networking. The SoC is a single chip CMOS coherent DP-(D)QPSK transmission transceiver. The PMC-Sierra PM6373 POLO 40G features chromatic dispersion (CD), polarization mode dispersion (PMD), second order PMD (SOP), and high-rate polarization tracking. The device will sample later this year. The POLO 40G is implemented in 40nm CMOS technology and packaged in a 480-pin 23mm x 23mm FCBGA package.
