100 Gigabit Ethernet optical transceiver market set for growth

Globally, 10G, 40G, and 100G optical transceiver revenues totaled $1.9 billion in 2016, up 18% from 2015, and are expected
to grow a further 10% to reach $2.1 billion for full-year 2014, according to the latest report from Infonetics Research.

In the first half of 2014 (1H14), 10G, 40G and 100G transceiver revenues grew 11% from the same period a year ago,
according to the report. This increase is due almost entirely to the increase in shipments of 100G WDM and 40G QSFP+ modules,
market research firm says. However, the long-anticipated ramp of 100 Gigabit Ethernet (100GbE) optical modules may be at hand.

"Major growth in the data center for 100 Gigabit Ethernet is on the horizon due to new silicon entering the market and lower-cost
QSFP28 optics, including SR4 and much cheaper 2-km LR4 optics," said Andrew Schmitt, principal analyst for carrier
transport networking at Infonetics Research. "Interest in 25GbE is also building momentum for a jump in these formats.

"In the telecom world, the market for 100G coherent equipment is controlled by five vendors – Alcatel-Lucent, Ciena, Cisco,
Huawei, and Infinera – who are vertically integrated, and this is preventing an incursion by standalone component vendors,"
he added. Infonetics forecasts the coherent WDM market to double in 2014.

Meanwhile, volumes in the metro 100G market are expected to ramp in a year and, according to service providers, this will be led
by data center and Internet content providers, Schmitt notes.

Interest in 100G data center network optics is accelerating, but has yet to be turbocharged by widespread data center deployment
in the way 40G QSFP optics have been.

Shipments of 40GbE QSFP optics in 1H14 were lower than anticipated due to softer demand from Internet content providers,
whose needs remain unpredictable, the market research firm says. Even so, growth in 40G data center interfaces is now
affecting 10G volumes, as QSFP+-based interfaces used for high-density 10G start encroaching; growth in the 10G datacom
segment is expected to slow down as a result starting this year, the firm suggests.
