ClariPhy's 28nm CMOS ADC/DAC Coupled With Sumitomo Electric's Indium Phosphide
Integrated Optics Meets Challenging Power and Size Requirements of CFP and
Paves the Way to Subsequent Generation Pluggable Modules

ANAHEIM, Calif., March 13, 2013 (GLOBE NEWSWIRE) -- ClariPhy Communications,
Inc., a leading developer of ultra-high speed systems-on-chips (SoCs) for
coherent optical networks, and Sumitomo Electric Industries, Ltd., a leading
global provider of advanced optical solutions, announced today a demonstration
of the world's first 100 gigabit per second (100G) coherent CFP technology
platform. The demonstration highlights significant breakthroughs in power and
size reduction for 100G coherent transmission, with ClariPhy showing the
industry's first 28nm CMOS analog to digital converter (ADC) and digital to
analog converter (DAC) suitable for 100G and 200G coherent transmission, and
Sumitomo Electric showing an indium phosphide (InP) based integrated coherent
optical engine. The demonstration comprises real-time transmission as well as
capture and detection of coherent signals in both QPSK and 16QAM modulation
formats. The combined solution also provides a roadmap to next generation
coherent interfaces in CFP2 and smaller form factors.

100G coherent technology is being rapidly adopted by carriers for long-haul
dense wavelength division multiplexing (DWDM) networks because of its
tremendous advantages in spectral efficiency and reach compared to the
previous generation of 10G (non-coherent) systems. However, the high cost,
power consumption and size of today's 100G coherent solutions make them
unsuitable for use in shorter reach metro networks and inter-datacenter links,
where cheap, pluggable 10G DWDM solutions such as XFP and SFP+ dominate. As
10G metro networks become overwhelmed by a surge in bandwidth demand, carriers
are calling for a 100G metro solution with the benefits of coherent (high
fiber capacity, dispersion tolerance and ROADM compatibility), but in a
pluggable form factor at a cost and power per bit that is comparable with or
better than 10G. Pluggability also allows reuse of line cards with 100G client
CFP interfaces for DWDM transmission and enables operators to scale their
metro transport networks to 100G and beyond with "pay as you grow"
flexibility. The technology demonstrated by ClariPhy and Sumitomo Electric
enables a 100G coherent interface within the 32W budget specified by the CFP
multisource agreement (MSA).

"2013 will be the year that Metro 100G solutions are evaluated and selected by
leading service providers, and pluggable coherent is near the top of their
list according to our service provider surveys. This allows them to extend
coherent 100G to vendor platforms without locking themselves into one
equipment vendor's coherent solution. ClariPhy and Sumitomo are clearly well
positioned to meet a market need," said Andrew Schmitt, Principal Analyst,
Optical, Infonetics Research.

The majority of power in a 100G coherent transmission system is consumed by
the SoC. A key element in reducing SoC power is migrating from today's
generation of 40nm and 65nm solutions to the state of the art 28nm CMOS
process, but such migration is gated by the availability of 28nm ADC/DAC
technology. ClariPhy has achieved an industry first by sampling 28nm silicon
containing a complete ADC and DAC, as well as a phase locked loop (PLL) driven
by a standard commercial reference clock source. The ENOB, bandwidth and
jitter performance of these 28nm analog blocks meet or exceed all requirements
for coherent transmission using 100G QPSK, 100G 16QAM and 200G 16QAM
modulations. ClariPhy is integrating these analog blocks into a single
coherent SoC with multi-rate (100G, 200G), multi-mode (QPSK, 16QAM)
capabilities as well as other best in class features. Combining the power
saving features of 28nm CMOS, power efficient design, and a flexible
architecture with a high degree of power vs. performance tradeoff capability,
ClariPhy's SoC will reduce power dissipation by as much as 65% compared to
coherently available ASICs.

By combining their respective power-saving, compact technologies, ClariPhy and
Sumitomo Electric will enable the world's first 100G coherent solution in a
CFP form factor in 2013 which is the first step on a roadmap of pluggable 100G
coherent modules that will include CFP2 and ultimately CFP4 solutions and will
drive down cost, power consumption and size similarly to what tunable XFP and
SFP+ modules have done for 10G DWDM interfaces. ClariPhy and Sumitomo Electric
have collaborated closely in the design of their respective components to
optimize power and performance for coherent CFP and CFP2 applications,
utilizing the DSP capabilities of ClariPhy's SoC to address the inherent
impairments of a pluggable solution such as insertion loss and reflections
caused by the CFP2 connector. By optimizing their solution at a system level,
the companies will offer OEMs a roadmap of robust pluggable coherent modules
that can integrate seamlessly into their systems.

"We are privileged to work with Sumitomo Electric on a 100G coherent roadmap
that will have such an important impact on the industry," said Dr. Paul Voois,
co-founder and chief strategy officer at ClariPhy. "We share the vision of
delivering the game-changing benefits of 100G coherent in the pluggable form
factors that have been and will continue to be so successful in optical
networking such as CFP, CFP2 and CFP4. With its vertically integrated indium
phosphide design and manufacturing capability, and its status as a world
leader in optical components, Sumitomo Electric is an ideal partner to work

"ClariPhy's proven ability to deliver power-saving coherent SoCs—including
successfully resolving the challenge of digital to analog converters in 28 nm
CMOS—will enable the world's first coherent CFP modules," said Manabu
Yoshimura, General Manager of Technology and Marketing Strategy Department at
Sumitomo Electric Device Innovations (SEDI). "ClariPhy provides us with the
advanced technology to create an industry roadmap for pluggable 100G coherent
modules that will reduce cost, power consumption and size."

ClariPhy and Sumitomo Electric will showcase their 100G coherent demonstration
in ClariPhy's private suite at the OFC/NFOEC trade show in Anaheim,
California, March 17-21, 2013. Access to the demonstration is by invitation
