Broadcom launch industry first CMOS 40G PHY for long haul optical transport

Broadcom, a provider of semiconductor solutions for wired
and wireless communications, has unveiled its next generation 40G physical
layer transceiver (PHY) chipset, designed to address the need for higher
bandwidth and lower power in Optical Transport Networks (OTN).


Broadcom’s 40G PHY chipset leverages CMOS technology for
40G optical transmission using DQPSK modulation, providing high reliability,
lower power consumption and shorter fab cycle time for long haul DWDM


“Our new CMOS 40G PHY chipset is a key breakthrough
for Optical Transport Networks. The increasing demand for higher bandwidth
content continues to push the industry rapidly toward 40G and beyond. At the
same time, optical transport network suppliers face increasing pressure to
deliver products that offer higher bandwidth and better reliability while
consuming less power,” said Lorenzo Longo, vice president & general
manager, High Speed Interconnect Products, Broadcom.


Broadcom’s 40G PHY chipset, including
the BCM84141 demultiplexer (Demux) for receiving data, and
the BCM84142multiplexer (Mux) for transmission, work together to deliver a
significant increase in network bandwidth and scale while significantly
reducing power consumption by more than 50 percent.

The high speed network port market is estimated to
hit $52 billion in 2015(2) as operators continue to upgrade legacy
networks to manage the increasing global demand for higher bandwidth.

 Broadcom’s 40G PHY chipset integrates high
performance more than 20 Gbps IOs, which is essential for developing future
devices that will support 100G optical transmission.


Broadcom announced its latest innovation for 4G/LTE microwave backhaul, the
BCM85620 system-on-a-chip (SoC).


BCM85620 is designed to address the need for higher
bandwidth in mobile backhaul and it delivers Gigabit bandwidth and beyond and
is the first SoC to combine a baseband modem and network processor in one chip.
