Thursday, June 28, 2012 at 2:59PM OpenFlow may be causing an industry stir as system vendors such as ADVA Optical Networking extend the protocol's reach to the optical layer, but analysts warn that it will take years before the technology benefits operators' revenues.
"We see OpenFlow as an additional solution to tackle the problem of network control"
Jörg-Peter Elbers, ADVA Optical Networking
Wednesday, March 7, 2012 at 8:19PM Cisco Systems has demonstrated 100 Gigabit transmission over a 3,000km span. The coherent-based system uses a single carrier in a 50GHz channel to transmit at 100 Gigabit-per-second (Gbps). According to Cisco, no Raman amplification or signal regeneration is needed to achieve the 3,000km reach.

"The days of a single modulation scheme on a part are probably going to come to an end in the next two to three years"

Friday, October 15, 2010 at 10:06AM In the second and final part, Rafik Ward, vice president of marketing at Finisar, discusses Google’s call for a new 100 Gig interface, the ECOC show, and what Finisar has learnt from running a corporate blog.
"Feedback we are getting from customers is that the current 100 Gig LR4 modules are too expensive"
Rafik Ward, Finisar
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 7, 2010 at 6:48AM 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.
Friday, August 6, 2010 at 8:26AM CIP Technologies is bringing its reflective component expertise to an EU-funded project to reduce the power consumption of optical systems.
System vendors will be held increasingly responsible for the power consumption of their telecom and datacom platforms. That’s because for each watt the equipment generates, up to six watts is required for cooling. It is a burden that will only get heavier given the relentless growth in network traffic.
"Enterprises are looking for huge capacity at low cost and are increasingly concerned about the overall impact on power consumption"
David Smith, CIP Technologies
