LUCENT
ADDS DWDM TRANSPORT TO ITS PROTOTYPE 10 GBPS ETHERNET MUX
Lucent Technologies announced DWDM compatibility for its
GigaChannel Ethernet multiplexer, a prototype device that transports
native Ethernet frames (without protocol conversion) at rates of 10 Gbps.
The device takes up to eight Gigabit Ethernet streams and multiplexes them
onto a single fiber link for transport across a campus or metropolitan
network. Native Ethernet framing is preserved, as are the payload, VLAN
tagging, quality of service, and other Layer-2 and Layer-3 services. The
new DWDM compatibility enables the
experimental GigaChannel Ethernet multiplexer to run across 40 km of
standard single-mode fiber using Lucent's WaveStar MetroPoint
point-to-point optical system, or across multiple 80 km fiber spans using
Lucent's long-reach WaveStar OLS 400G with online erbium-doped optical
amplifiers and dispersion compensation. http://www.lucent.com/press/0999/990927.bla.html

LUCENT
INTRODUCES FIRST COMMERCIAL 40 GBPS OPTICAL DEVICE,
TUNABLE LASERS
Lucent Technologies introduced a lithium niobate electro-optic
modulator operating at 40 Gbps -- four times faster than current
generation optical components, making it the highest speed commercially
available optoelectronic device. Lucent said its 40-gpbs modulator is
suitable for DWDM systems used in high-speed digital networks operating up
to SONET OC-768 and SDH STM-256 rates. The device supports the wavelength
range of 1525-1565
nanometers and requires a 6-volt power supply. Lucent is currently
shipping the 40 Gbps modulator. http://www.lucent.com/press/0999/990927.mec.html
Lucent Technologies' Microelectronics Group also introduced a 2.5 Gbps
wavelength-stabilized tunable transmitter for applications ranging from
200 to 640 km. The device enables network equipment manufacturers and
service providers to tune in one of four adjacent, 50-gigahertz
(GHz) channels, minimizing the need for a separate laser for each ITU-T
wavelength. http://www.lucent.com/press/0999/990927.med.html
Lucent Technologies, September 27, 1999
In August, researchers at Siemen's Transport System Laboratories
transmitted 80 wavelengths of 40 Gbps channels generated using an
Electronic Time Division Multiplexing ETDM system developed by Siemens. In
July, BT researchers demonstrated a high-speed optical gating device for
regenerating input signals at 80 Gbps line rates. Alcatel has also
announced 40 Gbps line rate tests earlier this year.
ERICSSON
PLANS OPTICAL CROSS CONNECT WITH WAVELENGTH ROUTING
Ericsson disclosed plans to build a next generation optical cross connect
featuring a reconfigurable OADM (Optical Add-Drop Multiplexer), dynamic
wavelength routing, wavelength protection/reuse/conversion, full SONET
support, low cost amplifier-free metro configurations and end-to-end
optical circuit network management. The ERION Optical Cross Connect, which
will be introduced next year, would allow service providers to route,
manage and provision individual wavelengths through their optical
networks. Ericsson said its forthcoming Optical Cross Connect enables
limitless combinations of interconnections between ring, bus and
point-to-point networks. Product specifics were not disclosed. http://www.ericsson.com

CHROMATIS
DEVELOPS SELECTIVE WDM FOR METRO NETWORKS
Chromatis Networks, a Maryland start-up with R&D in Israel, unveiled
its Selective Wave Division Multiplexing (SWDM) architecture for
delivering one or more wavelengths to those sites on a metropolitan fiber
ring that require multi-gigabit capacities, while allowing other sites on
the same ring to share less-expensive bandwidth that is not based on DWDM.
The Chromatis SWDM platform creates two rings on the same fiber: one is an
inexpensive single- channel ring that is shared by all network elements
and runs at 1310 nanometers, and the second is a multi-channel DWDM ring
running at 1550 nanometers. Chromatis technology manages the two separate
wavelength regions to make them appear as a single network. All sites can
communicate at a variety of speeds using the 1310nm-shared ring, while
only the sites that need very high bandwidth tap into one or more of the
1550nm DWDM wavelengths. Only the high-bandwidth sites pay for DWDM
optics. Chromatis plans to integrate SWDM with higher-level protocols and
will begin carrier tests in November. http://www.chromatis.com/news-092799.html

KPN
CONVERGES VOICE/DATA WITH ERICSSON'S ATM SWITCH AXD 301 AND
TELEPHONY SERVER
Dutch operator KPN International Network Service will deploy
Ericsson's ATM switch AXD 301 and Telephony Server to integrate voice and
data services in its pan-European network serving France, Germany, Italy
and Switzerland. The contract also covers use of Ericsson's AXE TransLocal
4 switches and Cross Border Interconnect technology. British Telecom and
Telia Denmark have previously selected Ericsson's multiservice integration
roadmap. http://www.ericsson.com/pressroom/19990927-0002.html

SIEMENS
INTRODUCES OC-192 OPTICAL REGENERATOR FOR WDM
Siemens announced a lower-cost 10 Gbps Optical Channel Regenerator
for long-haul transmission networks. The optical channel regenerator is
designed for optically amplified WDM systems that require 3R signal
regeneration (reshape, retime and regenerate). http://www.siemens.com

ADC
UPGRADES ITS CELLWORX ATM VIRTUAL PATH RING SYSTEM TO OC-48
ADC Telecommunications announced OC-48 capacity for its Cellworx
Service Transport Node (STN), a multiservice optical access platform that
uses ATM Virtual Path (VP) ring technology instead of SONET hierarchies to
manage bandwidth in fiber loop networks. ADC
said the bandwidth efficiency of the new upgraded Cellworx OC-48 enables a
carrier to potentially support the same level of customer traffic as it
would with a TDM-based OC-192/STM-64 SONET platform. The Cellworx STN is
currently deployed in seven communication networks, the Iowa
Communications Network and Midcontinent Communications, as well as
three reseller training/demonstration centers.

NORTEL
NETWORKS PROMOTES SECURE DSL WITH NETWORK-BASED FIREWALL
Nortel Networks announced a network-based solution for addressing
the security risks of always-on DSL lines. The network-based packet
firewall will be offered as a new feature on the company's Subscriber
Services System and Shasta 5000 Broadband Service Node (BSN) system.
The Shasta 5000 enables the aggregation of tens of thousands of DSL
subscribers in a single chassis. Its GUI-based policy management system
could be used to create and provision highly flexible firewall and other
service policies for thousands of subscribers. The company said that
unlike current segmentation mechanisms - e.g. based on number of IP
addresses assigned - network firewall based segmentation mechanisms could
not be spoofed or bypassed. Ten other DSL vendors have agreed to provide
interoperability with the Shasta 5000, including Cayman Systems,
CopperCom, Efficient Networks, FlowPoint, Jetstream Communications,
Netopia, Network TeleSystems, Promatory Communications, TollBridge
Technologies and Wind River Systems.
