CIENA
INTRODUCES ITS LONG DISTANCE OPTICAL TRANSPORT PLATFORM
Ciena announced enhancements to its MultiWave
CoreStream switch enabling the optical transport platform to support spans
longer than 5,000 km without additional optical-to-electrical signal
regeneration. The
enhancements would allow the CoreStream to support up to 160 channels of
10 Gbps traffic over a span of 2,000 km without regeneration, or scaling
to transport more channels or span greater distances.
The greater distances will be achieved using forward error
correction (FEC), nonlinearity management and dispersion mapping
technologies. Ciena estimates
that regeneration may account for up to 50% of the cost of transport in
some networks. Beta trials
are expected to begin in April 2000.

QTERA'S LONG-HAUL DWDM TESTED IN QWEST'S NETWORK
Qtera Corporation, a start-up based in Boca Raton,
Florida, said its all-optical, long haul photonic transport platform has
successfully completed a 30-day field trial in Qwest's network.
The Qtera platform carried 10 Gbps signals 2,400 km (or 1,440
miles) without any opto-electronic regeneration.
Qtera's long-haul platform also provides the ability to add/drop
wavelengths at any node. A
protection switching design enables traffic signals to be restored within
10 milliseconds, faster than SONET's 50 millisecond standard across far
shorter distances. Qtera
expects to begin beta tests soon using live commercial traffic.
Qtera is led by Fahri Diner, formerly with Siemens Information and
Communications Networks.
The company received financing from Battery Ventures, Mayfield Fund
and Oak Investment Partners, among others.

CORVIS' ALL-OPTICAL TRANSPORT TESTED BY QWEST
Corvis Corporation's all-optical transmission platform
completed its first phase of testing in Qwest's network.
The Corvis system allows the transmission of optical signals up to
3,200 km without electrical regeneration.
An upcoming field trial with Qwest is expected to demonstrate the
ability to transmit both OC-48 and OC-192 signals over the long distance
spans. http://www.corvis.com/news/press/press_22.html

Earlier this week, Corvis announced that Williams
Communications had also agreed to test its platform.
SPRINT
DROPS TELLABS' TDM-TO-ATM GATEWAY, TELLABS CONTINUES DEVELOPMENT WORK
Sprint has decided not to implement Tellabs'
TDM-to-ATM gateway, which was being developed under the JCS 2000 program
as a means of migrating Sprint's network to a voice over ATM architecture.
In a conference call, Tellabs officials said Sprint attributed the
cancellation of the program to a continued need to deploy traditional
voice switches in its network. Tellabs
plans to continue development of its AN2100 Gateway Exchange (GX) despite
Sprint's decision. A more
fully featured version of the AN2100 product will be ready for field
trials in mid 2000.

COVAD
AND ICG ANNOUNCE VODSL SERVICE PARTNERSHIP
Covad Communications and ICG Communications agreed to
jointly develop Voice over DSL service offerings.
ICG Communications, which recently sold its Netcom dial-up ISP
business to MindSpring, is now pursuing a Gateway Strategy to provide
access, transport and other services, such as VoDSL, to the Internet
service provider community. Additionally,
the agreement enables ICG to expand its national DSL footprint using
Covad's network. http://www.icgcom.com/investor/News/release.asp?date=1999-11-23

GTS ANNOUNCES PLANS FOR 6 MORE EUROPEAN CITY NETWORKS
Global TeleSystems Group
(GTS) will build high-density fiber networks in Frankfurt, London,
Vienna, Amsterdam, Madrid and Stockholm.
The company currently operates city networks in Paris, Berlin,
Prague and Budapest, and is preparing to launch metropolitan services in
Geneva.

GTS, November 23, 1999
Earlier
this week, GTS secured 500 million
Euro (US$514 million)
through high-yield bond offerings to fund expansion of its network.
GTS currently has 16,000
route kilometers of fiber in operation across Europe, representing 118,000
active "wavelength" kilometers based on its DWDM network.
GTS is a joint partner in FLAG Atlantic-1, a terabit capacity
trans-Atlantic undersea dual-cable system now under development.
MOBILKOM
TESTS GPRS FOR MOBILE COMMUNICATIONS
Mobilkom, Austria's main mobile communications network
operator, successfully tested GPRS (General Packet Radio Service) in
anticipation of commercial launch by summer 2000.
The test network uses Motorola's GPRS solution.
There are currently two million subscribers on Mobilkom Austria's
GSM A1 network. http://horizongprs.motorola.com
Motorola, November 23, 1999
GPRS supports packet access over GSM networks at
speeds up to 115 Kbps.
