In the latest of our WDM & Next Generation Optical Networking speaker interviews, Merrion Edwards, Regional Marketing Manager (EMEA & India) at Corning Optical Fiber, talks about her hopes for the event and thoughts on the industry. Corning are Platinum Sponsors at the event, and lead sponsor of the Submarine Optical Networking stream.
What are you looking forward to at the WDM and Next Generation Optical Networking show?
I am looking forward to the annual meeting of key minds in the optical transport industry and the opportunity to exchange industry knowledge on optical transport and fiber technology advances and their potential impact on optical transport trends
What do you feel are the key challenges that the optical networking industry is facing in 2013 and what do you hope the conference will answer?
A key challenge is how to meet the capacity demands of the future when many operators have a legacy network that may be performance and cost- challenged at data rates beyond 100G. A big question is, how long is it cost efficient to exploit legacy infrastructure and when should an operator make the move to deploy an advanced next generation optical fiber cable overlay.
Where has 100G has taken us so far and where is 400G & 1T likely to take us?
In western markets 100G has temporarily relieved capacity bottle necks and in emerging markets 100G has enabled life extension of low fibre count cables. 400G and 1T should provide further such capacity relief but the big question is over system reach. If 400G and 1T require significant additional regeneration stages on legacy optical fiber cables (as is most likely) then the cost per bit could spiral, making the deployment of advanced next generation optical fiber overlays a much more attractive proposition.
What are the practical evolution pathways for legacy networks?
Coherent systems are now available that enable 100G on most legacy G.652 and G.655 optical fiber networks. In addition a low cost non-coherent 100G solution exists that can operate over 600km reach on Corning LEAF G.655 fiber. Beyond that the options are as follows:
1. Deploy ever more complex and equipment intensive systems to deliver higher capacity, while limiting the fundamental optical fibre infrastructure upgrades to maintenance driven section replacement and upgrade
2. Deploy an overlay network using advanced optical fibre (ultra-low attenuation, maybe larger effective area) to enable lower cost, less complex and less equipment intensive systems and provide a platform for transition to even higher future data rates.
What are your views on OTN and ROADMs and their role in the next generation optical network?
Driving down cost per bit and increasing capacity utilisation are two key carrier profitability drivers. By enabling protocol and vendor transparency, OTN supports lower cost per bit, and ROADMs by enabling agile wavelength switching assist with increasing capacity utilization.
What do Cloud and SDN mean for next generation optical networking?
As the datacentres that support the Cloud migrate towards the core in search of lower cost energy and real estate, this increases the capacity pressure on core and regional networks.
Could you give a brief overview paragraph of what you will discuss during your presentation?
As we look beyond 100G transmission we see 400G and even 1T on the horizon. We explore drivers of this capacity demand (data center migration towards the core, high speed broadband with FTTH-LTE convergence and high speed home-networking), and how to use advanced optical fiber to deliver that capacity with lower cost, longer reach and lower latency. We consider the network dilemma faced by many carriers today: when to upgrade, when to invest, is there an alternative? And we reveal the benefits of early transition to a next generation advanced optical fiber infrastructure.
