Tamares Telecom partners with Grid Telecom to create ANDROMEDA, a subsea optical fiber cable system connecting Greece, Cyprus, and Israel, aiming to establish a new telecommunications corridor between Europe and the Middle East. This strategic alliance offers enhanced connectivity, network diversity, and low latency for wholesale customers across the region.

The SHEFA-2 underwater cable, which connects the Faroe Islands to Scotland’s mainland through the Shetland and Orkney Islands, suffered damage in two separate instances last week, rendering much of the island without Internet access.   In separate events, three critical subsea cables linking Marseille to Lyon, Milan and Barcelona were deliberately severed in the south of France, according to the cable’s operator, affecting internet service for consumers in Europe, Asia and the United States. Cloud service providers worked quickly to repair the backbone infrastructure.   According to a report by the cloud security company Zscaler, the unanticipated cable damage caused packet loss and increased latency for websites and apps transiting the damaged pathways.   While the French authorities believe sabotage occurred, their Scottish colleagues are still unsure of what actually severed the wires.   “We expect it will be fishing vessels that damaged the cable but it is very rare…

NEC Corporation, along with its subsidiary OCC Corporation and Sumitomo Electric Industries, has stated that they have conducted the first testing of an uncoupled 4-core underwater fiber cable and confirmed its transmission performance to fulfill the stringent requirements of global telecommunications networks.   International data usage is anticipated to increase by 30-40%  by 2026, owing to reasons such as the expansion of 5G mobile data and the necessity to exchange ever more content between data centers located around the world. Submarine networks are using space division multiplexing (SDM) technology to fulfill this need, which increases the number of separate spatial channels to maximize the overall capacity of the system, decrease energy usage and minimize the cost per bit transferred. Multicore fiber is projected to increase the number of parallel optical fiber cores without changing the size and structure of underwater cables, allowing the introduction of second generation of submarine SDM…
