LIME, the Caribbean arm of Cable & Wireless Communications (CWC), and Xtera (news) have finished up work on the Carribean East West Cable network. Spanning 1,700km the new cable hooks up Jamaica, the British Virgin Islands, and the Dominican Republic. Xtera's gear will enable an initial 120Gbps across the system, with the ability to expand to 720Gbps - higher with future technology. Here's a map I found lying around someplace:
This is the third cable lately in the region for CWC, following the CBUS and Gemini cables, as the company is adding both capacity and diversity to its incumbent markets. There have also been rumors of some sort of new Bermuda-Spain connectivity in the works.
