Broadcom Debuts CMOS 40G PHY for Long Haul Transport

Broadcom introduced its next generation 40G physical layer transceiver (PHY) chipset for Optical Transport Networks (OTN). The 40G PHY chipset is the first in the industry to leverage CMOS technology for 40G optical transmission using DQPSK modulation, providing high reliability, lower power consumption and shorter fab cycle time for long haul DWDM transmission.


Broadcom's 40G PHY chipset includes the BCM84141 demultiplexer (Demux) for receiving data and the BCM84142 multiplexer (Mux) for transmission. The chipset is currently in production with multiple customers. Visit Optical Transport Products to learn more.
