Operators know it all too well: streaming video, cloud
computing, the Internet of Things and the evolution to 5G place massive
pressure on today's networks, requiring capacity increases by orders of
magnitude and the ability to respond to even greater unpredictability in
traffic patterns. The optical network sits at the heart of communications,
connecting people, data centers and an increasing number of devices across any
distance, from next door to an ocean away.
With both the cloud and the IoT coming to dominate the
enterprise data environment, the need to push connectivity across greater
distances becomes paramount.
Recently, numerous platforms and service offerings have that
aim to forge tighter links not only between remote data centers, but between
individual server and storage components within those data centers. Ultimately,
the aim is to produce a single federated ecosystem that spans local, co-located
and cloud-based infrastructure, all defined on an abstract, virtual layer to
achieve limitless flexibility and scalability.
This requirement for high-bandwidth services comes
particularly from cloud service providers, who seek both higher bandwidth
networking and software defined network-enabled connectivity solutions. Data
center-based traffic is expected to nearly double by the end of the decade,
growing to 20.6 zettabytes in 2021 from 11.6 zettabytes in 2017, with the cloud
accounting for 95% of this traffic, according to Cisco's Global Cloud Index:
Forecast and Methodology, 2016-2021.
The significant escalation in enterprise traffic is manifest
in enterprises' migration of IT to public data centers and cloud services,
driving demand for cloud connect services and increasing Ethernet service
bandwidth by close to 30% annually, Coriant found.
Advances in Ethernet switches drives the data center
interconnect (DCI) market, reports research firm Ovum. The 100Gbit/s equivalent
DCI market will enjoy a compound annual growth rate of 56% between 2017 and
2021, driving the need for low cost 100Gbit/s over single lambda (wavelength)
solutions, Ovum found. At the same time the industry will start adopting higher
speed 400Gbit/s links also using single lambda technology. As 400G switches
enter the market, optical transceivers must keep pace and rapidly transition to
400Gbit/s.
A series of
three reports dives deeper into the state of the next generation optical
networking market as technologies and deployments ramp up from 100Gbit/s to
400Gbit/s and beyond.
