The market size of the worldwide 1G, 10G, 40G, 100G network port increased 5 percent in 2013 to $39 billion, said Infonetics Research.
Out of this, enterprise port revenue grew 5 percent, and service provider port revenue increased 4 percent.
Matthias Machowinski, directing analyst for enterprise networks and video at Infonetics Research, said that both enterprises and service providers invested in their networks to accommodate the growth in traffic, and revenue growth accelerated as buyers shifted to higher bandwidth and more expensive ports.
1G comprises major share of ports, while 10G delivers the bulk of revenue, though revenue growth is coming from the emerging 40G and 100G segments.
The 40G market is in transition as service providers are moving on to 100G.
40G is, however, finding success in the data center market, resulting in 40G port shipments more than doubling in 2013.
40G port shipments are expected to nearly triple this year to 1.5 million, said Infonetics.
100G ports almost quadrupled in 2013, thanks to surging service provider demand for 100G WDM
Infonetics said the first 100G ports on enterprise equipment started shipping in 2013, but aren’t expected to become a major factor until 2015.
Coherent 100G will be taking over the core, growing to nearly 80 percent of all wavelengths by 2016, effectively shutting down competing 10G and 40G deployments.
