A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables were laid beginning in the 1850s and carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858.
The Southern Cross Cable is a trans-Pacific network of telecommunications cables commissioned in 2000. The network is operated by the Bermuda-registered company Southern Cross Cables Limited. The network has 28,900 km (18,000 mi) of submarine and 1,600 km (990 mi) of terrestrial fiber optic cables, all which operate in a triple-ring configuration. Initially, each cable had a bandwidth capacity of 120 gigabit/s. Southern Cross offers capacity services from 100M/STM-1 to 100 Gbit/s OTU-4, including 1G, 10G and 40G Ethernet Private Line services.
Fibre-optic Link Around the Globe (FLAG) is a 28,000-kilometre-long fibre optic mostly-submarine communications cable that connects the United Kingdom, Japan, India, and many places in between. The cable is operated by Global Cloud Xchange, a subsidiary of RCOM. The system runs from the eastern coast of North America to Japan. Its Europe–Asia segment was the fourth longest cable in the world in 2008.
SEA-ME-WE3 or South-East Asia - Middle East - Western Europe 3 is an optical submarine telecommunications cable linking those regions and is the longest in the world.

Broadband Internet in Israel has been available since the late 1990s in theory, but it only became practically accessible to most customers in 2001. By 2008, Israel had become one of the few countries with developed broadband capabilities across two types of infrastructure—cable and DSL—reaching over 95% of the population. Actual broadband market penetration stands at 77%, ranked 7th in the world. In 2010, Israel was ranked 26th in The Economist's Digital Economy Rankings. In 2022, Israel was ranked first for digital quality of life by Surfshark.
