ClariPhy Granted
US Patents Enabling Standards-Based Testing of Networking Components
Inventions Incorporated in High-Speed
Networking
Standards Covering 10G Ethernet, Fibre Channel, Serial Attached SCSI,
and SFP+
Modules
The
inventions, covered by US patents 7,643,752 and 7,664,394, describe a
method to
test transmitters and a method to test intermediate components when the
final
receiver includes an equalizer. The
methods distinguish between impairments that the equalizer can
compensate and
those that it cannot compensate.
“Testing
the transmitters was a vexing problem during the early development
stages of
10GBASE-LRM,” said Dr. Norm Swenson, Co-founder and CTO of ClariPhy
Communications, and a co-inventor of the technology.
“Simple eye diagrams were insufficient, and
building a hardware reference receiver would have been
cost-prohibitive.”
“We
are gratified that the ClariPhy contribution has proven beneficial to
the
industry, as evidenced by its widespread adoption,” said Dr. Paul Voois,
Co-founder
and CEO of ClariPhy.
In
addition to the patents granted and pending, ClariPhy holds copyrights
on the
MATLAB™ code used to describe the underlying algorithm.
ClariPhy has agreed to license the
intellectual property required to practice various standards under a
reasonable
and nondiscriminatory basis. For
licensing information, please contact Dr. Swenson.
