On the Road to IP and Optics Convergence

By: Peter Bernstein, Senior Editor

For what seems like ages now the communications industry has been talking about convergence. We have already gone through many phases as networks move from TDM to being end-to-end Internet Protocol (IP) with voice traffic increasingly being carried on converged networks.  Indeed, the popularity of Voice-over-IP (VoIP) and the coming of Voice-over-LTE (VoLTE) on mobile networks is the future.  

That said, convergence is not just about IP but is also about the transformation of global network infrastructures in the wired world, with legs into the wireless one as well, of IP and Optics.  And, as Steve Vogelsang, VP Strategy and CTO, IP Routing and Transport Business Division, Alcatel-Lucent noted in a recent TechZine blog, IP and optics: Time to make nice, “Let’s face it. The future of the communications industry requires a convergence of IP and optics. So maybe it’s time to give each other some overdue respect."

Coherent Technology Enables the Seamless Upgrade to 100 Gb/s

Susan J. Campbell

The demand for data consumption and rich multimedia interactions is driving the call for 100 Gb/s. Fortunately, coherent technology in high-performance electro-optics engines enable the cost and performance benefits of such transmissions to be viable commercially. 

A recent Alcatel-Lucent TechZine article by Sam Bucci, Vice President and General Manager, Terrestrial Optics, entitled, Coherent Technology: Making 100 Gb/s Viable, focused on how fiber impairments can decrease the performance and quality of the data transmission as speeds increase. It made a compelling case that such impairment can be overcome with coherent technology which ensures performance and cost benefits are optimized.
