Q&A: Ciena’s CTO on R&D
Gazettabyte spoke with Steve Alexander, CTO of Ciena, about optical technology and R&D. In Part 1 of the Q&A, Alexander shares his thoughts about the practice and challenges of R&D.
Part 1: R&D
"The R&D model has shifted a lot. Time has marched on and there are newer ways of doing things"

The table shows the selected players in AT&T's domain supplier programme announced to date.
AT&T has stated that there will likely be eight domain supplier categories overall so four more have still to be detailed.
Looking at the list, several thoughts arise:
Still some way to go
Briefing: Dynamic optical networking
Part 1: The vision .... back in 2000
I came across this article (below) on the intelligent all-optical network. I wrote it in 2000 while working at the EMAP magazine, Communications Week International, later to become Total Telecom.
What is striking is just how much of the vision of a dynamic photonic layer is still to be realised. Back then it had also been discussed for over a decade. And bandwidth management, like in 2000, is still largely at the electrical layer.
And yet much progress has been made in networking technology. But the way the network has evolved means that a more flexible photonic layer, while wanted by operators, is only one aspect of the network optimisation they seek to reduce the cost of transporting bits.
Ciena post-MEN
Ciena has been busy since completing the acquisition of Nortel’s Metro Ethernet Networks (MEN) business back in March.
“The 40G and 100G technology were key to the deal and we made sure that the core team was still there”
