Carriers Pumping Cash Into DWDM

The vast majority of telecom operators are in the throes of increasing the capacity on their DWDM backbones, with only a tiny minority planning on sticking with what they have, according to a new global carrier survey conducted by Heavy Reading.

The survey results, based on feedback from more than 60 carriers from all over the world, show that nearly 80 percent of those operators are either expanding their DWDM capacity right now or are planning to do so next year, while only 2 percent have no plans to beef up their DWDM backbones.

"A great deal of attention has been put on the metro of late, but what we are finding here is a real willingness among carriers worldwide to stop patching up their core DWDM networks and move to adopting new generations of technology to solve long-term scalability issues," says Clavenna.

The carriers were also asked about their approach to 100-Gbit/s wavelengths. More than 40 percent say they're investigating the enabling technology, but none are trialing it. Only 16 percent said they had no interest.

These survey results are just some of the data points collected by Heavy Reading Chief Analyst Scott Clavenna and his team ahead of The Future of Optical Networking, a one-day conference taking place at the Langham Hotel in London on Tuesday, December 12.

Further data from the carrier survey, plus Heavy Reading's latest optical market forecasts (including MSPPs worldwide, long-haul DWDM, and ROADM systems) will be included in presentations at the event.

Clavenna, who is moderating the conference, will be tackling such issues as:

  • The factors driving the current optical networking market resurgence

  • How WDM systems are evolving in light of new networking requirements

  • The role of the optical layer in an IP NGN network, with panel session contributions from Ciena Corp. (NYSE: CIEN), Infinera Corp. (Nasdaq: INFN), Transmode Systems AB , and Tropic Networks Inc.

  • The impact of business Ethernet services on metro and core optical network requirements and whether Ethernet transport might replace Sonet/SDH, with panelists Alcatel-Lucent (NYSE: ALU), Ciena, and Meriton Networks Inc.

  • The impact that triple-play access network and service rollouts will have on metro and core optical networking, including a panel discussion involving ADVA Optical Networking , Ciena, and JDSU (Nasdaq: JDSU; Toronto: JDU)

  • What future optical network architectures will look like
The day's debate will also include discussion about one of the optical sector's fiercest current debates -- Provider Backbone Transport (PBT), the new controversial flavor of Ethernet transport, versus Transport Multiprotocol Label Switching (MPLS) (T-MPLS), its nearest direct rival for carrier hearts and minds.

And with the event being held in London, home to the headquarters of one of PBT's most outspoken supporters, BT Group plc (NYSE: BT; London: BTA), the debate is set to be lively.

re: Carriers Pumping Cash Into DWDM A lot of money may have been invsted in DWDM upgrades this year, with more to come in 2007 and beyond, but is anyone making any money from it? Or have the margin pressures generated by a desperation for new business and additional competition from China eased any?
