 Adds Cable Diversity, Reliability
 MIAMI--(BUSINESS WIRE)--Columbus Networks has completed cable installation on the first phase of an undersea fiber optic express route that connects Colombia with Florida. The company expects to illuminate the first of two fiber cable segments and begin offering service in April.
 The first-phase undersea cable segment links Cartagena, Colombia and Morant   Point, Jamaica. Installation work is continuing on the second phase of the cable   that connects Jamaica to Florida in Boca Raton. The principal operator of the   ARCOS undersea network, Columbus Networks expects to complete the second leg of   the express route in July.
 
 Once complete, the express route will provide customers in Colombia with the   most direct route, an increased performance and the lowest latency data and IP   connection to the USA, adding data traffic diversity, redundancy, and improved   network reliability.

 "Columbus Networks clearly recognizes the importance of the   thriving Colombian market on the regions' overall growth and   economic expansion," said Paul Scott, president of Columbus   Networks. "We decided to build the express route and add cable   diversity to better meet increasing bandwidth demand, and to more evenly   distribute communications traffic across a multi-path network."
 
 Columbus Networks' Colombia-Florida Sub Sea Fiber Project, dubbed   "CFX", includes more than 2,400 kilometers of deep-sea   repeated high-capacity fiber optic cable. It also includes a new landing station   in Cartagena where other regional communications providers are co-located for   interconnection with Columbus Networks.
 
 CFX is the largest network expansion project the company has undertaken since   Columbus Communications acquired the company in September 2005.
