Wednesday, October 13, 2010 at 9:13AM 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
Tuesday, September 21, 2010 at 5:02AM 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"

“It would be irresponsible of any system vendor to overlook a solution that can bring a cost advantage to their customer”

Part 2: 40 and 100Gbps optical transmission
The market for 40 and 100 Gigabit-per-second optical transmission is set to grow over the next five years at a rate unmatched by any other optical networking segment. Such growth may excite the industry but vendors have tough decisions to make as to how best to pursue the opportunity.
Market research firm Ovum forecasts that the wide area network (WAN) dense wavelength division multiplexing (DWDM) market for 40 and 100 Gigabit-per-second (Gbps) linecards will have a 79% compound annual growth rate (CAGR) till 2014.
In turn, 40 and 100Gbps transponder volumes will grow even faster, at 100% CAGR till 2015, while revenues from 40 and 100Gbps transponder sale will have a 65% CAGR during the same period.
Yet with such rude growth comes uncertainty.
“We upgraded to 40Gbps because we believe – we are certain, in fact – that across the router and backbone it [40Gbps technology] is cheaper”
Jim King, AT&T Labs.
Systems, transponder and component vendors all have to decide what next-generation modulation schemes to pursue for 40Gbps to complement the now established differential phase-shift keying (DPSK). There are also questions regarding the cost of the different modulation options, while vendors must assess what impact 100Gbps will have on the 40Gbps market and when the 100Gbps market will take off.
“What is clear to us is how muddled the picture is,” says Matt Traverso, senior manager, technical marketing at Opnext.

Part 1: The start-up
Ofidium is a 100 Gigabit start-up that refuses to follow the herd.
While the optical industry has chosen polarisation-multiplexing quadrature phase-shift keying (PM-QPSK) for 100 Gigabit-per-second (Gbps) transmission, the Australian start-up is developing a module based on orthogonal frequency division multiplexing (OFDM) modulation.
"For data rates higher than 100Gbps, it [OFDM] is the only way to go"
Jonathan Lacey, CEO
Friday, March 12, 2010 at 6:26AM AT&T’s 100 Gigabit-per-second (Gbps) coherent trial between Louisiana and Florida detailed earlier this week was notable for several reasons. It included a mix of 10, 40 and 100Gbps wavelengths, Cisco Systems' newest IP core router, the CRS-3, and a 100Gbps line-side design from Opnext.
According to Andrew Schmitt, directing analyst of optical at Infonetics Research, what is significant about the 100Gbps AT&T trial is the real-time transmission; unlike previous 100Gbps trials no received data was block-captured and decoded offline.
