DWDM

[Scott E. MacKenzie]

Does anyone know where I can locate a list of DWDM networks deployed for
Education, Science & Research, and Commercialization?

We need to determine the practicality of DWDM use...

you seem to have missed menog unfortunately. you may want to come to
the afren meeting in rabat coming up, where things such as this are
covered pretty deeply.

The UK research and Education network is based on a DWDM backbone as far
as I know. Some of the regional networks on the Janet backbone also use
DWDM.

The current technologies for DWDM have really made it technology
that's reasonably straight forward to deploy. The last
generation was a nightmare!

Tuneable optics, dispersion compensation, and ROADM have made
a substantial difference to deploying and operating DWDM networks.

I had experience with the former generation system from Nortel
which although very reliable it was very resource intensive
to deploy new services, the latest CPL technology from Nortel
is a real breakthrough, for once a vendor has listened and understood
the challenges for operators and actively addressed our concerns.

Here's a map showing some of the regional optical networks
run by the R&E community. There's a lot more unrepresented
here, especially in metro environments.

Most of this stuff is then connected into NLR, Internet2.

Highly practical, and the latest network planning tools seem
to be halfway decent from the 2 vendors we use.

europe is similar. some of asia is similar.

scott might better have asked what r&e communities were not dwdm.

re: "the latest CPL technology from Nortel is a real breakthrough, for once a
vendor has listened and understood the challenges for operators and actively
addressed our concerns."

When CPL was appeared I found its architecture refreshingly straightforward, as
you've also noted, which was best demonstrated (to me, at least) by Kees Neggers
within SURFnet6 throughout the Netherlands about three years ago (thus allowing
him to offload boatloads of Layer3 gear).

I'm not sure which issue of the Cook Report it was in, but the details of this
SURFnet6 deployment were captured in an interview of Neggers quite nicely by
Gordon Cook in one of his reports during that era.

During the intervening three years, however, advancements in dispersion
management have been introduced and opened the door for some new players, such as
Infinera, whose use of electronic dispersion compensation (EDC) in its WDM
platforms has now given it somewhat of an edge, or so it seems at the moment,
based on the market share it has gained in a very short time. I'm hardly
suggesting that Infinera trumps the former CPL approach across all areas of
design consideration, but only that it's an approach that merits investigation.

I should note that Infinera went diametrically against the grain of the
"all-optical" holy grail that is commonly sought by many, and actually leverages
its ability to perform functions in the 'electronic' domain a lot more
efficiently than other vendors have been capable of achieving in the purely
optical domain, thus positioning itself in a category that's pretty much all its
own today. I'd be eager to read comments and criticisms from anyone who's had
actual experience with its wares.

Frank,
Agreed, the infinera platform is very good also.
thanks for he link.
