A quick overview of submarine communications cable systems in the Caribbean.<\/em><\/p>\n
TeleGeography<\/a>\u00a0maintains a free interactive map of active and planned submarine communications cable installations worldwide. The data used is from Global Bandwidth Research Service, a TeleGeography\u00a0property, and is updated\u00a0regularly \u2013 the most recent was 31 January 2013. Figure 1 is an excerpt of the global map and shows submarine cables and their landing points around the Caribbean basin. The cables shown have\u00a0a maximum\u00a0upgradeable capacity of at least 5 Gbps\u00a0(or 5,000 Mbps).<\/p>\n

There are at least 15 independent submarine cables connecting Caribbean\/CARICOM countries<\/p>\n
Table 1 provides a quick summary of the number of submarine cables or landing points in individual Caribbean countries.<\/p>\n

As is, Figure 1 can be quite overwhelming. Table 2 highlights a few of the important submarine cables in the English-speaking Caribbean<\/p>\n

1. \u00a0Similar to fibre optic cables on land, submarine cables are expensive to deploy; hence many developing countries tend to rely on wireless, especially satellite, solutions to provide\u00a0international connectivity. However, wireless services can be expensive for consumers, have speed limitations, and for voice and Internet services in particular, the time delay in reception, due to distance, can result in poor service quality. On the other hand, once submarine cables are deployed, they tend to be more cost-effective and reliable on major routes.<\/p>\n
2.\u00a0 Cables can be\u00a0broken.\u00a0 Fishing trawlers, anchors, earthquakes, turbidity currents among other things, are typical culprits. You may recall that the 2010 earthquake in Haiti had damaged the submarine cable systems to that country. In the aftermath of the disaster, one of the first order of business was to re-establish connectivity, which in the first instance, was achieved via satellite and other wireless solutions.<\/p>\n
3.\u00a0 According to the International Cable Protection Committee<\/a>, the following international treaties protect submarine cables:<\/p>\n
4.\u00a0 Transmission speeds on submarine cables are dependent on, among other things, the condition of the cable, the distance being covered and the equipment connected to the cable.<\/p>\n
As of 2012, operators had \u201csuccessfully demonstrated long-term, error-free transmission at 100 Gbps\u00a0across Atlantic Ocean\u201d routes of up to 6000 km, meaning a typical cable can move tens of Terabits\u00a0per second overseas. Speeds improved rapidly in the last few years, with 40 Gbit\/s having been offered on that route only three years earlier in August 2009… <\/em>(Source: Twisted Sifter<\/a>)<\/p><\/blockquote>\n
