The tools of the spy trade included listening/recording devices, super telephoto lenses, a submarine, a stylish and aloof international man or woman and, most importantly, a very fast car, plane or speed boat. At least, that’s what the James Bond movies led us all to believe ...

Every time Ethernet increases by a factor of ten, or Fibre Channel accelerates by a factor of four, analysts carefully probe the pricing factors involved in determining the slope of user acceptance. The arrival of 10G Ethernet was slowed significantly by the price of some semiconductor logic components, and by the price of implementation in line cards. At other times, the shifting price differentials in multimode vs. single-mode fiber, or pricing of different laser types (VCSEL, DFB, Fabry-Perot) has been named as a key factor in determining how quickly fiber networks scale to a new speed grade, whether in LAN, SAN, MAN, or WAN.

For nearly ten years, storage and virtualization analysts who were supposedly in the know, predicted the imminent demise of Fibre Channel, to be displaced by protocols such as iSCSI or FCoE riding atop 10G Ethernet. Given the splash many storage vendors have made over 16G Fibre Channel, the ubiquity of Ethernet is nothing to anticipate in the next few quarters. So what happened?

Whether interconnecting facilities in support of high-frequency trading, high-performance computing, business continuity, disaster recovery, migration of virtual machines among physical servers or some other demanding application, there are certain networking requirements that tend to be shared among enterprise data-center managers. Optical networking is not a commodity technology space, and data-center managers must investigate at least seven primary areas of technological differentiation in doing their due diligence to deploy the right solution for their given organization’s specific interconnection requirements:
