Okay, next week it's DWDM week! Sorry I am very busy at the moment, but will try and post as much DWDM stuff as possible over the next week to give an insight. It is more than likely that Ericy leads in Europe on this, although the US came up with the goods some time back (although I do not know how commercially deployed it is there?). Up until summer Alcatel was also waving a DWDM banner, but since then I have heard nothing. Earlier this year I saw that Nokia were pushing it, but alas, since then nothing. It does not heavily rely on previous transmission/transport sales, but it does help! In which case, Ericsson should do well overall. We may just be at the beginning of a whole new fixed infra sales boom (so it is not nescessarily just mobile handsets etc.). Hope people are waking up to the idea that there is more than that to telecomm's -than what they might read on the other threads! ;) Smiley happy people, Mika PS Don't forget even the 3G debate that we will need highbandwidth infra to convey all the information. WCDMA promotes ATM as the architecture of choice, and here Ericy is also at the forefront.

Tim, While we wait for Mika to put Ericsson's WDM into terms that I can understand, here are some links ....... 1. From Ericsson Review, issue no 3, 1988 -http://www.ericsson.se/Review/er3_98/art4/art4.html ERION--Ericsson opticalnetworking using WDM technology By Magnus Grenfeldt 2. ericsson.se 'Networker' joins the ERION™ family, safeguarding investment & reputation while offering 'new technology, not a new network' On show at CommunicAsia is Networker, the newest member of the Ericsson Optical Network (ERION ™) portfolio. This 16-32 wavelength Dense Wavelength Division Multiplexing (DWDM) system has been chosen by both BT and Telefónica for intensive field tests. Dirk Uhlemann Ericsson's Transport and Cable Networks Global Marketing Director said that the interest shown by both BT and Telefónica is a strong vote of confidence for ERION™ and, in particular, the Networker's unique, patented failure protection mechanism. Describing the ERION 'flexing bus' optical protection device as, "Networker's most important advantage over competing DWDM offerings", Mr Uhlemann said: "ERION's™ optical fault protection safeguards a company's investment in infrastructure and reputation. When you're carrying half a million calls which might be lost with a single failure, optical fault protection is a crucial advantage". Deployed in a ring network configuration, Networker's 'flexing bus' can autonomously switch traffic from one bus configuration to another in the event of failure in the fibre. The 'flexing bus' is fast, independent and operates under equipment control, independent of network management. Meeting the demands of the bandwidth explosion is another powerfully important motivation for deploying Networker. Made possible by breakthroughs in laser technology, ERION's™ Networker uses multiple wavelengths, or 'colours', of light fired down a single fiber to multiply its' capacity. It effectively solves the problem of fibre exhaustion by carrying multiple traffic streams on a single fibre pair. As well as helping carriers avoid laying new fibre while meeting growing demands on capacity, ERION™ optical networking technology allows the information capacity of current generations of transmission equipment to be maximised, and provides a migration path to future transport systems based on ATM and fast IP interconnect. Mr Uhlemann said that the ERION™ system offers, "new technology, not investment in a new network". The ERION product family is an integral part of the Ericsson Transport Network Architecture (ETNA™). ETNA provides an integrated transport infrastructure for all telecommunications services, including Plesiochronous Digital Hierarchy (PDH) and Synchronous Digital Hierarchy (SDH). More than 70 customers in over 50 countries worldwide have already chosen transport network systems from Ericsson. Mardy.
