BELL
LABS ESTIMATES THEORETICAL CAPACITY OF FIBER AT 100 TBPS
Scientists
from Lucent Technologies' Bell Labs published a paper in
the British journal Nature in which they estimate that
the theoretical capacity of a standard, commercially
available fiber strand is approximately 100 Tbps. Current
commercial DWDM systems operate at under 2 Tbps and lab
experiments have shown the potential for 10 Tbps
systems. Previous
estimates for fiber capacity have ranged from 50 – 350
Tbps. The
Bell Labs study took a multi-disciplinary approach to
calculate the theoretical spectral capacity. http://www.lucent.com/press/0601/010628.bla.html

360NETWORKS
FILES FOR BANKRUPTCY PROTECTION
360networks
filed for bankruptcy protection under Canada’s
Creditors Arrangement Act and under Chapter 11 of the US
Bankruptcy Code. Its
European subsidiaries will also initiate insolvency
proceedings. The
company and the subsidiaries have $155 million in
remaining cash, which they hope to use to maintain
service to existing customers in Canada and the US, and
to complete key segments of its North American network.
Further growth would require additional financing
or strategic investment into the reorganized company.
Yesterday, 360networks
announced the layoff of approximately 800 employees.

June 28, 2001
- As
of May 15, 360networks had completed about 35,700 km
of its planned 43,000 km network.
About 22,000 km were lit and in commercial
service. Construction
of 13 of approximately 20 planned metro area
networks in the US and Canada was completed,
including networks in Seattle, Toronto and Calgary.
In Europe, 360networks had lit approximately
9,800 km of its long haul network.
The company had also completed and was in the
process of lighting metro networks in London,
Amsterdam, Frankfurt and Paris.
In Q1, 360networks also completed
installation of its 11,700 km undersea transatlantic
cable, as well as about 15,000 km of its undersea
and terrestrial network between North America and
South America.
KPNQWEST
COMPLETES EURO RINGS ON SCHEDULE
KPNQwest
connected two new OC-192 self-healing rings in its
“EuroRings” network.
The new Eastern and Southern rings connect 13
cities (of which 4 are new additions to its network)
across 3,900 km in Austria, the Czech Republic, France,
Germany, Italy and Switzerland.
Each ring consists of 120 fiber strands, capable
of delivering 80 wavelengths per strand at up to 10 Gbps
per wavelength, giving it more than 96 Tbps of
macro-capacity when fully lit.
KPNQwest now has connected 40 out of 50 cities in
its planned network.

WHITE
ROCK NETWORKS OFFERS GIGABIT ETHERNET IN MINI SONET ADM
White Rock
Networks, a start-up based in Dallas, Texas, added full
line-rate Gigabit Ethernet capabilities to its line of
mini SONET add/drop multiplexers (ADM).
White Rock Networks’ OC-192 SONET add/drop
multiplexer (ADM) measures two rack units (3.5 inches)
in height - one-fifth the size of the smallest
competitive OC-192 multiplexer.
Its OC-48 SONET
ADM measures one rack unit in
height. http://www.whiterocknetworks.com
White Rock Networks, June 29,
2001
- In May, White Rock
announced details of a software-embedded
control plane supporting OSPF-TE/GMPLS inter-working
between optical cross-connects and also between edge
access devices.
White Rock’s “VLXconnect” control plane
sets up connections between devices in the network
so that multiple systems can communicate after being
provisioned once.
The company said its control plane
infrastructure allows carriers to establish
connections in a White Rock SONET network in
seconds. When
the emerging signaling standards are adopted by
other equipment vendors, such as cross-connect
system vendors, the same end-to-end provisioning
will work in a heterogeneous network.
- White Rock Networks
was founded in November 1999 by Lonnie Martin
(previously President of ADC’s Business Broadband
Group), Tony Masella (previously Vice President
& General Manager of ADC’s Transport Systems
Division) and Greg Lowe (previously Vice President
of Engineering for ADC’s Transport Systems Group).
WEST
BAY LAUNCHES HIGHEST DENSITY OC-3/STM-1 FRAMING
PROCESSOR
West Bay
Semiconductor, a start-up based in Vancouver, Canada,
introduced a 16
x 155 Mbps channelized framing processor for SONET/SDH
systems – its first product.
The device incorporates clock and data recovery
(CDR) units and terminates datapaths down to the STS-
1/VC-3 level. West
Bay’s framing processor includes the SONET/SDH
framing, full overhead processing, alarm detection,
performance monitoring, tandem connection processing,
line and path bit error rate monitoring (BERM) and
complete STS-1/VC-3 timeslot interchange that supports
traffic grooming and automatic protection switching.
It also includes an On-line Fault Detection
feature that ensures user traffic integrity in the
entire datapath. Applications
could include multi-service routers, switches, access
concentrators and DWDM equipment.
Samples are currently shipping.

REDBACK
ATTRIBUTES 30% DROP IN Q2 REVENUES TO DELAYED CARRIER
PURCHASES
Citing
a continuing weak global telecommunications market,
Redback Networks cut its forecast for Q2 revenues to
approximately $55 to $60 million, resulting in a pro
forma loss of approximately $0.27 to $0.32 per share.
Quarterly expectations were in the $90 million
range. Redback
plans to take a significant inventory write down charge.
In a
conference call, the company said all the major ILECs
purchased Redback’s products in Q2, but that many
orders were delayed as carriers chose to slow down
deployments and reallocate existing network capacity.
This included Williams, Genuity, SBC, and Bell
South. Redback
believes these networks will continue to be expanded and
that orders for its subscriber management systems have
only been delayed.
The company does not expect any cutbacks in staff
as it expects the market to recover.
