RESEARCHERS CLAIM BREAKTHROUGH IN OPTO-ELECTRIC MODULATORS
Researchers at the University of Southern
California and the University of Washington claimed that new
polymeric electro-optic modulators can achieve
information-processing and bandwidth speeds as great as 10 times
those of lithium niobate crystals currently used as electro-optic
modulators. The new
electro-optic modulators require less than one-sixth of the power
used by crystals. Potential applications include ultra-fast
analog-to-digital conversion, signal transduction for cable
television, directional couplers or routing switches in optical
communications networks, optical switching elements in flat panel
displays, modulators in phased-array radar systems and voltage
sensing for the electric utility industry.
The modulators are fabricated and integrated with both
silica fibers and VLSI silicon chips.
The research was funded by the National Science Foundation,
the U.S. Air Force Office of Scientific Research and the Office of
Naval Research.

ADTECH
INTRODUCES FIRST OC-192C IP TEST SOLUTION
Adtech
introduced the first OC-192c IP test solution.
The new
OC-192c Generator/Analyzer,
which is part of the Adtech AX/4000 Broadband Test System,
generates up to 1,020 test streams, with each stream containing
billions of traffic flows. Users
can test class of service technologies, including MPLS and
DiffServ, as well as create sophisticated real-time traffic
distribution models with variable IP packet lengths and
interarrival times. The
module also auto-identifies and analyzes incoming substreams
simultaneously, based on virtually any type of IP traffic
classification. In addition to providing a complete set of QoS
measurements for each substream at full-rate, the analyzer will
provide full-rate capture for IP error characterization and
protocol decoding. OC-192c IP QoS testing can be performed in
conjunction with other Adtech IP QoS test modules, which cover a
variety of media types and speeds from SONET OC-3 through SONET
OC-48 including POS, IP/ATM, IP/Frame Relay, Gigabit Ethernet and
10/100 Ethernet. http://www.adtech-inc.com

ENNOVATE
AND ENSIM PARTNER For Hosted Applications over IP VPNS
Ennovate
Networks Inc. and Ensim Corporation announced a marketing and
technology partnership targeting hosted applications over IP
virtual private networks (IP VPNs).
The joint solution combines the Ennovate Envoy 1600
multi-services switch and the Ennovate EnSight Service Automation
System with Ensim’s ServerXchange application hosting
platform. Ensim’s ServerXchange convertes any server
running Linux, Solaris or NT into multiple private servers.
These virtual servers are linked to a virtual router on the
Ennovate Envoy 1600 platform.
The solution uses an IP VPN to guarantee security and
application quality of service without dedicating an entire
physical server to each customer.

LUMENON
DEVELOPS WWDM FOR GIGABIT ETHERNET LAN/MAN/WAN
Lumenon Innovative Lightwave Technology initiated development
of a new line of 1.3-micrometer Wide Wavelength Division
Multiplexers (WWDM) designed for parallel physical layer Gigabit
Ethernet for the LAN, MAN and WAN markets.
The company said its WWDM line would be an inexpensive, low
loss, small form product to support both the installed fiber base
of 62MMF and 50MMF links at 300M and 10km on SMF.

GIGA
A/S COMPLETES OC-192/STM-64
LINE CARD SOLUTION
GiGA A/S, which
was recently acquired by Intel, introduced a 10 Gbps Forward Error
Correction single chip transceiver and an OC-192/STM-64 Section
and Line Termination single chip transceiver.
Last mont, GIGA introduced STM-64/OC-192 transmitters and
receivers for SDH/SONET and DWDM applications.
With the devices, GIGA said it now can offer a complete 10
Gbps line card solution for OC-192/STM-64 SONET/SDH transmissions
systems. http://www.giga.dk/

ATM
VENDORS COMPLETE P-NNI INTEROPERABILITY TESTING AT EANTC IN BERLIN
Manufacturers
of ATM network components and analyzers met recently in the
laboratories of EANTC AG in Berlin, Germany to test the
interoperability of their devices in hierarchical P-NNI ATM
networks, as defined by The ATM Forum.
The tests covered three
major scenarios: routing
and signaling between 3 vendors; routing and signaling in large
simulated PNNI networks; and construction of large networks.
EANTC
reported that significant progress has been made on
interoperability since its last round of interoperability tests in
December, but highlighted some problems that still need to be
addressed concerning establishment of the routing channel between
higher level peers. Participants
in the test included Adtech/Telcordia, Alcatel IND, Cabletron
Systems, Cisco
Systems, Data Connection, GN Nettest Canada, IBM Global Services
ITS and Marconi/Fore Systems.
