![]() ![]() In our post earlier this year, We are more connected than we think, we began to highlight the multiple submarine cable systems that currently operate in the Caribbean using Figure 2 below. How does the Caribbean fare in comparison to the Cayman Islands? ![]() LIME indicated that Internet and phone customers would experience some degradation, and even intermittent failure, of service during the period the MAYA-1 was down (Source: Caymanian Compass). Thereafter, the traffic from the Cayman Islands would leave Jamaica through up to three submarine cables that connect to the United States.Īlthough LIME/Cayman Islands was able to use the Cayman-Jamaica Fiber System as a back up to the MAYA-1, the transition was not especially smooth or transparent to consumers. In the two days until service on that cable was restored (30 July), the international traffic carried on the MAYA-1, which would have been originated from a number of local providers including LIME, was routed through the Cayman-Jamaica Fiber System, another submarine cable network also owned by CWC, LIME’s parent company. This first repeater is some 47km out to sea, and at this stage there is no definitive information on the exact location of the impairment that is causing the shunt fault so LIME’s team is continuing to work with local resources, suppliers and the other MAYA landing stations on this matter. The failure is preventing the local power feeding units from reaching their operating output levels and forcing them into shutdown mode despite numerous attempts to restore them. LIME’s initial findings are that the Maya-1 Cable System has suffered a shunt fault at on Segment 6, which is located between Half Moon Bay (Cable station) and Repeater 1 (Line Amplifier) in Cayman. On 28 July, LIME, the incumbent telecoms provider in the Cayman Islands, and the local operator of the MAYA-1 submarine cable, announced that a major failure had occurred along the cable: The project is set to be completed by 2022 but, as Google knows all too well from its experience with the Pacific Light Cable Network, international projects of this scale have a habit of encountering obstacles.Figure 1: MAYA-1 route map and select specifications (Sources: MAYA-1 & TeleGeography) MAYA-1 failure in Cayman Google’s new cable will also harness new optical fibre switching techniques to increase reliability, allowing the company to “better move traffic around outages.” The undersea web cable will be the first of its kind to use the technology, which Google says it is looking forward to integrating into other systems going forward. For context, the current fastest cable (jointly owned by Microsoft and Facebook) has eight fibre pairs and achieved record speeds of 26.2Tb per second last year. Grace Hopper will boast a whopping 16 fiber pairs - more than any cable in use today. “Private subsea cables allow us to plan effectively for the future capacity needs of our customers and users around the world, and add a layer of security beyond what’s available over the public internet,” explained the company. In response to ever-increasing capacity requirements, the world’s technology giants have taken it upon themselves to fund and manage many undersea cabling projects, as shown by Google’s latest endeavor. ![]()
