OpenFlow extends its control to the optical layer

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

100 Gig: Is market expectation in need of a reality check?

Recent market research suggests that the 100 Gigabit-per-second (Gbps) era is fast-approaching and that 100Gbps promises to leave the 40Gbps market opportunity in its wake.


“It could easily be ten to 15 years before we see 100Gbps in a big way on the public network side”

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"
