Cablevisión in 100Gbit/s backbone speed boost

Cablevisión, Argentina's largest pay-TV operator, will become the first MSOs in South America to have an optical network able to backhaul traffic at 100 Gbit/s.
The announcement was made by Alcatel-Lucent, the telecoms equipment maker that will provide the technology required. The next-generation network's main new component will be the 1830 Photonic Service Switch.
The technical upgrade will allow Fibertel, the cable operator's ISP, to increase the speed of its broadband services in the future. But a more immediate beneficial impact that the company should notice would be an improved efficiency (cost per bit) in the backbone portion of its HFC network.
Like virtually every other ISP in the world in recent years, Fibertel has seen an explosion in multimedia content consumption (particularly video and, increasingly, HD video) pushing its optical infrastructure dangerously close to its limit.
By raising its data transmission capacity ceiling to 100 Gbit/s (the highest possible throughput available today), the MSO will be looking to anticipate exponentially growing bandwidth demand over the next few years. But, crucially, the move will allow Cablevisión to remain competitive in the pay-TV business.
Customers are demanding TV bouquets with an increasing participation of HD services. This is an area where DTH operators can – and, in general, have – responded with greater agility due to their intrinsic satellite capacity advantage.
Having a more powerful fibre optics network (indeed, the most powerful in the Southern Cone) will allow the Grupo Clarín-owned MSO to launch new HD channels in the very near future.
This is vital for the company. Unlike what's been happening in Brazil and Mexico (Latin America's two other large pay-TV markets, where DTH has already become the dominant delivery platform), the cable industry in Argentina still commands the largest number of subscribers.
