Inphi Announces Porrima Gen2 Single-Lambda PAM4 Platform for Hyperscale Data Center and Cloud Networks
February 11 2019 - 8:00AM
Inphi Corporation (NYSE: IPHI), a leader in high-speed data
movement interconnects, today announced its Porrima™ Gen2
Single-Lambda Pulse Amplitude Modulation (PAM4) platform with
integrated laser drivers that reduces optical module Bill of
Material (BOM) cost and enables sub-10 watt 400Gbps QSFP-DD optical
transceiver modules for wired network infrastructure – including
hyperscale cloud data center, service provider and enterprise
networks.
The new Porrima Gen2 platform, based on the
successful and field proven Porrima chipset, enables client optics
module deployment for both 400Gbps and 4x100Gbps applications with
breakout mode support. Porrima Gen2 DSP also has an integrated
laser driver with direct-drive capability, which reduces the total
cost of ownership and module power consumption. Inphi already
announced Porrima Gen1 platform at OFC 2018, which has been the
industry’s leading platform with proven performance that includes
PAM4 DSP, Linear TIA and Driver. Leveraging six generations of DSP
development, Inphi has developed optical platform expertise and an
API-based DSP software suite that achieves quick time-to-market
with the right trade-offs in power and performance for data center
optical interconnects.
“InnoLight currently offers
100G single lambda DR, FR and LR and multiple 4x100G
optical solutions to accelerate the 100G
per lambda migration. Inphi’s Porrima Gen2 is
the key
driver for our successful delivery of
these solutions. We are very appreciative
of Inphi’s time to market and leading-edge
technology to enable the 100G per lambda module
platform,” said Osa Mok, Chief Marketing Officer
of InnoLight Technology.
“Inphi’s excited to launch the Porrima Gen2
platform with integrated complementary metal-oxide-semiconductor
(CMOS) driver capability for hyperscale data center and cloud
networks,” said Siddharth Sheth, SVP, Networking Interconnect at
Inphi. “Absorbing driver functionality into the DSP saves our
customers BOM cost and power for their 400G DR4 and FR4 solutions,
as we prepare for the upcoming 12.8T ecosystem production
ramp.”
“The development of 400G modules is especially
challenging and market demand is such that both power consumption
and cost have gating thresholds that must be met for volume
deployment,” said Dale Murray, Principal Analyst for LightCounting
Market Research. “By integrating the laser driver into their Gen2
Porrima DSP chip, Inphi has not only simplified module development
but now offers meaningful module power reduction as well.”
Key attributes and benefits of the new
400Gbps Porrima Gen2 PAM4 platform:
