“Coherent COBO; CohOBO Applications” is a Guide for Coherent
400 Gbps Data Center Interconnect Applications
SAN DIEGO–(BUSINESS WIRE)–lt;a href=”https://twitter.com/hashtag/COBO?src=hash” target=”_blank”gt;#COBOlt;/agt;–The Consortium
for On-Board Optics (COBO) today announced the availability of a new
application note Coherent COBO; CohOBO Applications, detailing
how to utilize the COBO standard in coherent Data Center Interconnect
The application note identifies CohOBO applications and details
different use cases, module design considerations, management interface
and other implementation details for developing COBO-based coherent
networking equipment at 400 Gbps and higher capacities.
CohOBO solutions provide an advantage for networking companies building
DCI networking equipment because they are designed to optimize airflow
and lower the system power dissipation with modules in proximity of the
switch silicon. In addition, CohOBO technology maximizes front-panel
port density for 400 Gbps and higher capacity networks when compared to
today’s pluggable optics alternatives.
Builds on COBO Specification
The application note was written by the COBO Coherent Working Group and
expands on the COBO specification. The document focuses on Class C
modules, which are designed to accommodate the necessary optical
engines, digital signal processing (DSP) components and power-density
required for a coherent solution.
“The DCI application is taking off as data center operators split their
workloads among multiple data centers to keep up with growing demand for
data,” said CohOBO Working Group Chair, Hugues Tournier of Ciena. “The
use of COBO standard for coherent optical communications enables DCI
technology to use the same footprint as short reach optics.”
COBO will be located in booth #1817 at OFC 2019 in the San Diego
Convention Center in San Diego, CA. The application note will be
available online at http://onboardoptics.org/.
