Aelis Photonics Unveils Processing
Solution For Networks
Aelis Photonics, Inc., an emerging innovator in dynamic optical signal
processing, unveiled an adaptive optical equalization technology that will
dramatically extend the reach and speed of optical networks.
The company will deploy its patent-pending ReachExtender technology in
adaptive optical equalizers designed to enable cost-effective high-bit-rate
optical networks by allowing cost sharing across multiple optical channels and
phase distortion phenomena. Optical equalizers can reduce intersymbol
interference and improve the bit error rate several decibels better than the
best electrical equalizers.
"In developing ReachExtender technology, our multi-disciplinary team
applied
to optical networking the principles of adaptive equalization used in wireless
communications," said Menachem Tipris, Aelis' chief executive officer. The
result is a breakthrough technology for simultaneous mitigation of multiple
phase distortion sources -- chromatic dispersion, polarization mode dispersion
(PMD) and self-phase modulation (SPM) -- in multiple optical links, using a
single optical device. It tackles dynamic link impairments that limit optical
transmission reach and upgradeability and cause unpredictable random system
outages.
"Other companies address link impairment problems in an optical or an
electrical way, but all other solutions on the market today have their
limitations," Tipris added. "They can correct only one wavelength at a time,
or only one dispersion phenomenon at a time, or only to a limited degree.
ReachExtender technology is much more flexible and efficient than the other
solutions."
Targeted at telecommunications carriers and OEMs of optical network
equipment,
ReachExtender technology will provide adaptive equalization of 10- and 40-
gigabits-per-second (Gbps) optical links. Aelis will incorporate the
technology into a single device that handles multiple impairment sources and
multiple optical channels and will enable long-haul transmission by
compensating up to 300 picoseconds total delay spread (at 10 Gbps) resulting
from PMD, chromatic dispersion and SPM. The Aelis solution reduces capital and
operating expenses by extending transmission reach to the noise-limit, which
can save carriers several million dollars per link in regeneration costs (20
channels at 40 Gbps); allowing use of legacy fiber plant for 10- and 40- Gbps
transmission; minimizing outage time; and decreasing maintenance costs.
Aelis has successfully tested its new ReachExtender technology in the
laboratories of several leading OEMs and carriers and plans to introduce its
first adaptive optical equalizer product in 2004. Meanwhile, the company is
scheduling private demonstrations of the technology at the Omni Hotel (at CNN
Center) during the OFC Conference in Atlanta, March 23-28. Interested OEMs and
carriers should e-mail Eran Yarkoni at eyarkoni@netvision.net.il.
