" They don't NEED to commit to today's WDM technology."

OK, if the qualifier is now "today's WDM," then I see their point. But this is slightly different from your last post on this point which stated:

"According to Nacchio, QWST is not currently, nor does it have any future plans to buy or deploy WDM technology for it's fiber network."

Alright, I took that to mean "never," which it still sounds like to me, but perhaps I shouldn't have. Game Point: Steve!

>>The article goes on to suggest (perhaps as per your re-read) that the Cisco exploration with CIEN of WDM networks is as an argument to IP Terarouter startups like Juniper and (QWST testing) Avici (who are collaborating with NT on the carrier grade IP terarouter. And per PR: "..Nortel intends to develop independent optical wavelength capability to enable interworking between Avici IP switches and Nortel IP-optimized backbone networks...")<<

All very interesting that some players are going about developing independent optical capabilities, but when it comes to winning mega-contracts with RBOC densification projects, they have to stick to the interoperability standards as prescribed by Bellcore and Telecommunications Management Network (TMN) dictates. Unless, of course, they want to view the short list from a distance.

I've reviewed some of Bell Atlantic's qualifying criteria for WDM vendor acceptance. Unless a vendor's line of xWDM is capable of operating with, and being co-managed with, other vendors (this also includes uniform GHz separations between optical channels, and TMN element management parameter adherence), that vendor is out of the running.

Concerning safety, an IBEW fiber-optic splice foreman I know (well, he still carries a union card, anyway) received a stripped-back three quarter-inch fiber "end" in his foot (half in, half out), after stepping on it in a work area on a trading floor while wearing regular leather shoes. Right through the leather, and into the sole of his foot. Serious business. No fooling.

Good night, Steve, and All.

An interesting and somewhat long article I posted concerning IP-over-SONET on the VoIP board, at

Steve,

This may well be overdone and glossed up a bit, as to the actual levels of science involved, but note the number of interfaces supported by this Cambrian-LU DWDM arrangement:

>SONET/SDH, Gigabit Ethernet, D 1 Video, fiber channel, ESCON<

I know of situations here in NYCity where MFNX has been supporting IBM's ESCON along with SONET interfaces between different parts of the city for some large brokerage firms, and the techies are just crazy about it, since it's saving them an enormous bundle on recurring costs. FYI

Cambrian Systems and Lucent Technologies Collaborate to
Demonstrate Interoperability of Optical Networking
Systems

June 2, 1998

KANATA, Ontario, June 1 /PRNewswire/ via NewsEdge
Corporation -- Optical networking leaders Cambrian
Systems and Lucent Technologies today announced
their collaboration on interoperability between their
metropolitan and long-haul Dense Wavelength Division
Multiplexing (DWDM) systems. Interoperable DWDM
products enable service providers to build flexible,
scalable, cost-effective networks.

Both companies successfully completed initial testing
between Lucent's WaveStar(TM) OLS 40G and
Cambrian's OPTera(TM) Metro DWDM systems, as well
as Lucent's WaveStar OLS 40OG long-haul DWDM
system. Cambrian and Lucent will demonstrate
interoperability of their systems at SUPERCOMM'98 in
both the Cambrian Booth (#8051) and Lucent Booth
(#6639).

This collaborative effort focuses on optical interworking
through open interfaces and includes joint testing of
end-to-end transmission across multiple DWDM
systems. In addition, Cambrian and Lucent are exploring
unified network management and applications for
specific customers.

"In the competitive local network, DWDM-based optical
transport networks are critical to the service providers
ability to effectively manage rapid, unpredictable growth
and to meet increasing bandwidth demands. Cambrian
believes the value of DWDM will be greatly enhanced
for our customers through coordinated and tested
interoperability. We are committed to full support of the
standards process, but also recognize the value of
working with other leading DWDM providers such as
Lucent Technologies to extend the application of optical
technology in carriers' networks," said Don Smith,
president and CEO of Cambrian Systems.

Cambrian and Lucent are also evaluating joint support of
those standards that will best accelerate the
development of widespread interoperability for the
industry as a whole.

"It's added insurance for carriers when their optical
networking equipment is not only standards compliant,
but fully compatible with systems from different
vendors," said Gerry Butters, president of Lucent's
Optical Networking business. "Our joint testing and
progress with Cambrian is further proof of Lucent's
commitment to developing products that are truly
interoperable, enabling service providers to take
advantage of the most advanced optical technologies in
their network while maximizing cost efficiency."

Lucent's WaveStar OLS 40G directly supports a full
range of SONET and high-speed data rates used in
metropolitan areas. This system allows service providers
to economically transport a wide range of services, such
as voice, video and data, with the same circuit pack over
the same fiber -- providing ultimate flexibility and cost
control in meeting the need for rapid service deployment.
Designed by Bell Labs, Lucent's WaveStar OLS 40G
provides a wide array of interface options -- OC-3, 12 and
48 SONET rates, as well as any data rate or format in the
150-750 Megabit per second. In addition, the system
supports up to 16 wavelengths configured in a wide
variety of network architectures -- including ring, linear
and flexible add/drop -- and supports span distances of
up to 132 kilometers.

Also designed by Bell Labs, Lucent's WaveStar OLS
40OG provides up to 400 gigabits per second over a
single strand of fiber -- record-breaking capacity that's
well ahead of competitive systems available today. This
single-platform system is the first to enable
communications providers to grow incrementally from
one to 80 wavelengths, or channels. This optical
networking system can be configured to handle up to
eight fibers, each transmitting 400 gigabits per second, to
give communications providers a maximum capacity of
3.2 terabits (or 3.2 trillion bits) per second of voice, video
and data traffic. That's equivalent to transmitting over
90,000 volumes of an encyclopedia in one second.

Cambrian Systems' OPTera is a survivable metropolitan
DWDM transport system delivering 32 wavelengths or
channels for a total capacity scalable to 80 gigabits per
second over a single strand of fiber. OPTera's modular,
cost-effective architecture enables direct bit-rate and
protocol independent transport of a broad range of
signals including SONET/SDH, Gigabit Ethernet, D 1
Video, fiber channel, ESCON and other signal formats up
to 2.5 gigabits per second with or without optical
amplifiers. Per wavelength optical supervisory channel
and ring protection switching enable flexible, high
quality service delivery. OPTera offers DWDM
metropolitan transport solutions for the future, today.

Cambrian and Lucent indicated that further work on
interoperability will continue through the remainder of
the year, and further progress is expected to be
demonstrated at the National Fiber Optic Engineering
Conference (NFOEC) in September.
