n the data center, speed is everything.
The challenge is to look ahead and know
what you have to be prepared to deliver
– in the immediate future and later on –
and chart the most expedient and flexible
course forward. Dell’Oro predicts Ethernet switch revenue
will continue to grow through the end of
the decade, with a large share allocated to
25G and 100G ports.
The faster that available technologies and
applicable standards evolve, the harder
that job becomes. The growing affordability of 100G switch
links – multimode and singlemode – is
enabling many companies to update their
switch networks from 10G directly to
100G, skipping 40G altogether.
Recent data center trends continue
to predict 25 to 35% annual
growth in data center traffic and
bandwidth requirements.

This demand for more network capacity
can only be supported by a shift to higher
switching speeds, which is precisely what
is now happening in the market.
According to Dell’Oro Group, shipments of
25 Gbps and 100 Gbps ports increased to
more than one million in the first quarter
of 2017.
Migration strategies are evolving as well.
The shift to 25G lanes is well underway
as well, with 25G-lane switches becoming
more commonplace.
Meanwhile, the entrance of proprietary
and standards-based PAM-4 modulation
has ushered in the introduction of 50G
lane rates.
The increasing popularity of 25G and 50G
ports continues to affect uptake of 40G
server attachments. ◊
