SAN MATEO, Calif., June 11 -- The first substantial deployment of 40 Gbs-per-channel, long haul network equipment in revenue traffic will occur in 2004. According to a study by the marketing firm Electronicast, this will follow the advancement of key singlemode components from their current qualification/evaluation status to substantial commercial shipments in 2003. Key components singled out by the study include transmitter/receiver pairs (and related modulators), chromatic and polarization mode dispersion compensators and 40 Gb/s-optimized fiber. The forecast outlines 40 Gbs-per-channel singlemode link component trends and 20-480 Gb/s (and up) throughput multichannel/multifiber links for LH/ULH, metro/access, LAN/MAN/WAN and intra-equipment applications. Forty Gb/s single-channel transmitter-receiver (T/R) pairs are forecast to gain a 59 percent share of the over-10 Gb/s throughput fiber link global consumption in 2003, reaching $447 million. The consumption value of multifiber link T/Rs is forecast to grow faster than 40 Gb/s-per-channel T/Rs, with multifiber market share expanding from 41 to 63 percent during 2003-2006 reaching a combined $1.87 billion.
