Since ECOC launched in 1974, things have certainly changed, with the introduction of revolutions such as the Internet and Dense Wavelength Division Multiplexing (WDM). But things could change even more radically in the next 30 years, reckons Per Andersson, conference chairman and director of business development for Ericsson AB (Nasdaq: ERICY). "Maybe one day we will all have fiber to the home -- and report the results at ECOC 2034,” he quips.
Back in the present, vendors had plenty of developments to announce here at the show. Here’s our pick of the most interesting ones:
CoreOptics, which also makes its own modules, supplied a custom EDC chip for Marconi to build into its transponders. Separately, CoreOptics announced that it is using tunable lasers from Santur Corp. in its own transponder modules.
“In that market, where people fight for a few tenths of a decibel, that’s a lot,” contends Dexter Johnson, its director of laser products and manufacturing. The extra senstitivity will allow equipment makers to relax requirements in other parts of the system. Samples are ready for shipping.
At the moment, vendors sidestep the issue of routing 10-Gbit/s signals by breaking them down into four lower-speed channels, but this gets problematic as more and more channels are terminated on the board. The polymers used by Dow Corning are inorganic polymers, which are closely related to materials that are already proven in the electronics industry for processes such as encapsulation, says Babette Pettersen, Photonics program director, Europe.
