Wave Division Multiplexing (WDM)
Version
1.0, Nov. 5th, 1998
Experiment leader
Victor Reijs, SURFnet bv, The Netherlands
Participants
IT, FR, NL, ???
Goals
- exchange information between the participants on the use of WDM in
WAN-networks.
- test in a small environment, WDM on international links (if possible!!!
otherwise LAN/MAN environment).
- get an idea on fiber quality,
management and resilience issues of WDM provision.
Description
Wave Division Multiplexing is an emerging technology to get high bandwidth
on a single fiber (pair), upto at least 640 Gbit/s. Over this technology it is
possible to transport IP over SDH over WDM
(the present way of doing it) and, in the future, IP over WDM.
This activity will primarily streamline experience exchange gotten on a national
or local environment.
There will perhaps not be many posibilities to test
WDM on international fibers (although there is perhaps a BE-NL fiber possibility),
but at least exchanging information will be done on how to connect router/switches [interfaces: IP over SONET over WDM or IP over WDM] in an NRN
environment to WDM
equipement (like WDM repeaters, OADM [Optical Add and Drop Multiplexers], OXC
[Optical X-cross Connets]). Also discussions will take place on the type of
fiber needed ('normal' or 'zero dispersion' type).
Pre-requisites
None
Dates and phases
- ongoing
information exchange
- 1Q,- 2Q 1999
define possible test on LAN/WAN's with WDM
- 3Q - 4Q 1999
testing WDM in LAN/WAN environment by participants (tests can hosted in one country if no WAN WDM connectivity is used/available)
- 4Q 1999
write down experience on management, resilience and technology issues
Network infrastructure
Dark fiber (type is yet unknown)
Local infrastructure
Be to decided.
Hard- and software
- Routers/switches/conversion boxes that have the possibility to connect to a WDM
infrastructure.
- WDM equipement
