Q&A with Rafik Ward - Part 1

In the first of a two-part interview, Rafik Ward, vice president of marketing at Finisar, talks about 40 and 100 Gigabit optics, emerging market opportunities and why this is the best time for a decade to be in the optical components industry.   

 

"This is probably the strongest growth we have seen since the last bubble of 1999-2000." Rafik Ward, Finisar

Google and the optical component industry

Google caused a stir at ECOC by requesting a new 100 gigabit-per-second (Gbps) interface, claiming the existing 100 Gigabit standards fall short of what is needed.

According to a report by Pauline Rigby, Google wants something in between two existing IEEE interface standards. The 100GBase-SR10, which has 10 parallel channels and a 125m span, has too short a reach for Google.

 

“What is good for an 800-pound gorilla is not necessarily good for the industry. It [Google] should have been at the table when the IEEE was working on the standard."

Daryl Inniss, practice leader, components, Ovum

Cisco Systems' coherent power move

Cisco Systems’ acquisition of CoreOptics means the company has largely cornered the coherent market, says Telecom Pragmatics. 

Cisco Systems announced its intent to acquire the optical transmission specialist CoreOptics back in May. CoreOptics has digital signal processing expertise used to enhance high-speed long-haul dense wavelength division multiplexing (DWDM) optical transmission. Cisco’s acquisition values the German company at US $99m.

 

"Let me be clear, we don’t believe 100Gbps serial will dominate the market for a long time, or 40Gbps for that matter"

Mark Lutkowitz, Telecom Pragmatics

Bringing WDM-PON to market

Significant power, size and cost challenges must be overcome before WDM-PON will be widely deployed.

 

 "We see just one way to bring down the cost, form-factor and energy consumption of the OLT’s multiple transceivers: high integration of transceiver arrays"

Klaus Grobe, ADVA Optical Networking

 

Considerable engineering effort will be needed to make next-generation optical access schemes using multiple wavelengths competitive with existing passive optical networks (PONs).

Such a multi-wavelength access scheme, known as a wavelength division multiplexing-passive optical network (WDM-PON), will need to embrace new architectures based on laser arrays and reflective optics, and use advanced photonic integration to meet the required size, power consumption and cost targets.

To efficiency and beyond

Briefing:  Dynamic optical networks

Part 3: ROADM and control plane developments

ROADMs and control plane technology look set to finally deliver reconfigurable optical networks but challenges remain.

Operators are assessing how best to architect their networks - from the router to the optical layer - to boost efficiencies and reduce costs.  It is developments at the photonic layer that promise to make the most telling contribution to lowering the cost of transport, a necessity given how the revenue-per-bit that carriers receive continues to dwindle.
