WDM and 100G: A Q&A with Infonetics' Andrew Schmitt

The WDM optical networking market grew 8 percent year-on-year, with spending on 100 Gigabit now accounting for a fifth of the WDM market. So claims the first quarter 2014 optical networking report from market research firm, Infonetics Research. Overall, the optical networking market declined 2 percent, due to the continuing decline of legacy SONET/SDH.

In a Q&A with Gazettabyte, Andrew Schmitt, principal analyst for optical at Infonetics Research, talks about the report's findings.

Q: Overall WDM optical spending was up 8% year-on-year: Is that in line with expectations?

AS: It is roughly in line with the figures I use for trend growth but what is surprising is how there is no longer a fourth quarter capital expenditure flush in North America followed by a down year in the first quarter. This still happens in EMEA but spending in North America, particularly by the Tier-1 operators, is now less tied to calendar spending and more towards specific project timelines.

This has always been the case at the more competitive carriers. A good example of this was the big order Infinera got in Q1, 2014.

NFV moves from the lab to the network

Service providers have long covetted the efficiencies achieved by hyperscale data centre operators running applications on servers. The telecom operators want their networking functions to run on servers in the cloud, instead of having to buy - and maintain - custom boxes running proprietary software for each new service.  

Dor Skuler

In October 2012, several of the world's leading telecom operators published a document to spur industry action. Entitled Network Functions Virtualisation - Introductory White Paper, the document stressed the many benefits such a telecom transformation would bring: reduced equipment costs, power consumption savings, portable applications, and nimbleness instead of ordeal when a service is launched.

Netronome prepares cards for SDN acceleration

Source: Netronome

Netronome has unveiled 40 and 100 Gigabit Ethernet network interface cards (NICs)  to accelerate data-plane tasks of software-defined networks.

Dubbed FlowNICs, the cards use Netronome's flagship NFP-6xxx network processor (NPU) and support open-source data centre technologies such as the OpenFlow protocol, the Open vSwitch virtual switch, and the OpenStack cloud computing platform.

OFC 2014 industry reflections - Part 1

Gazettabyte is asking industry figures for their thoughts following the recent OFC 2014 exhibition and conference: the noteworthy developments and trends, what they learnt at the show, and the topics to track in the coming year.  

T.J. Xia, distinguished member of technical staff at Verizon

The CFP2 form factor pluggable - analogue coherent optics (CFP2-ACO) at 100 and 200 Gig will become the main choice for metro core networks in the near future. 

I learnt that the discrete multitone (DMT) modulation format seems the right choice for a low-cost, single-wavelength direct-detection 100 Gigabit Ethernet (GbE)  interface for data ports, and a 4xDMT for 400GbE ports.

Ciena uses software to dip into the photonic layer

Ciena has enhanced its control plane and line elements to enable software to control the optical networking layer. The additions are part of Ciena's OPn network architecture evolution to enable greater visibility and automation. "It is about putting software into a system to allow you to program the photonic line," says Michael Adams, vice president of product & technology marketing at Ciena.

"For an SDN controller to control a photonic line, we need to present it as a programmable layer. The infrastructure is now there to be programmed."

Books in 2013 - Part 1

Gazettabyte is asking various industry figures to highlight books they have read this year and recommend, both work-related and more general titles.

Part 1:

Tiejun J. Xia (TJ), Distinguished Member of Technical Staff, Verizon

The work-related title is Optical Fiber Telecommunications, Sixth Edition, by Ivan Kaminow, Tingye Li and Alan E. Willner. This edition, published in 2013, includes almost all the latest development results of optical fibre communications.

My non-work-related book is Fortune: Secrets of Greatness by the editors of Fortune Magazine. While published in 2006, the book still sheds light on the 'secrets' of people with significant accomplishments.
