Is optical networking back to life?

Is optical networking back to life?

Perhaps? In fact some positive facts on the optical market were highlighted during 3Q05 financial reviews. Some tiny quakes were noticed by some vendors in terrestrial and submarine systems, in metro networks as well as in long haul systems. Even component vendors noticed the fact. JDSU saw increases in metro and long-haul activity. Operators also seem more likely to to spend on optical again. As an example, Level 3 has been rebuilding its entire optical footprint in a six-month period in US and Europe, growing capacity by a factor of two or three. It is new. How long capacity increase has been scrapped from our vocabulary? Probably for the past four or five years. Something is changing therefore. Main trends today seem Gigabit Ethernet and 10G Ethernet support, intelligence control plane for dynamic IP routing, GMPLS and ROADMs.
