Opnext Demonstrates Record-Breaking 3,300km Transmission Distance Using 100Gbps Coherent PM-QPSK Subsystem on SURFnet DWDM Infrastructure
FREMONT, Calif. & UTRECHT, Netherlands--(BUSINESS WIRE)--
Opnext, Inc. (NASDAQ:OPXT), a global leader in high speed optical
communications technology, and SURFnet, the National Research and
Education Network (NREN) in the Netherlands, today announced a
successful 100Gbps coherent field trial between the National
Supercomputing Center, SARA, in Amsterdam and CERN (Conseil Européen
pour la Recherche Nucléaire - European Organization for Nuclear
Research) in Geneva. Opnext used its OTS-100FLX 100Gbps digital coherent
subsystem for the field trial, utilizing next-generation 100Gbps single
carrier technology and soft decision forward error correction (SD-FEC)
to optically link Amsterdam to Geneva with a transmission distance of
1,650km using only erbium doped fiber amplifiers (EDFAs).
To further demonstrate the subsystem's performance, the embedded fiber
link comprised a combination of the relatively high-nonlinear TW+ and
TWRS fibers. Furthermore, the circuit was optically looped back in
Geneva, thus creating a 3,300km circuit. The looped-back 3,300km link
operated error-free for more than 23 hours (BER < 10-15)
over the entire C-band and over a range of launch powers, highlighting
the true upgrade potential of this link to 8Tbps in the future using
100Gbps coherent transponders.
"This trial is another clear demonstration that coherent 100Gbps PM-QPSK
transmission technology is tolerant to a very large range of impairments
(i.e. chromatic dispersion, polarization mode dispersion, noise) and
allows the use of alien wavelengths in research networks over DWDM
systems from multiple vendors," said Roeland Nuijts, Optical Network
Architect for SURFnet. "Transmission distance and tolerance against
different impairments will be critical going forward as we look to build
out international networks across geographic and administrative borders
in order to realize a global facility for research networking."
The Opnext subsystem consists of a suite of OTS-100FLX 100Gbps
flexponder line cards and a newly released OTS-mini ETSI shelf with a
4RU small form factor.
"It is great to see the results of our 100Gbps coherent product
development deliver both the capacity and reach needed to scale
next-generation optical networks around the world," said Mike Chan,
President of Opnext's subsystems business unit. "SURFnet's 3,300km field
trial really pushed us, and our 100Gbps coherent technology met the
