In the metro, investment is rapidly rotating away from legacy SONET/SDH to packet-optical transport systems that combine optical and Ethernet circuit switching in the same chassis.” The group’s research also found the OTN transport and switching equipment market grew 8 percent last year to $7.3 billion, with North America the top purchaser. Infinera is the North American supplier of choice, it adds.
