The Guernsey-Jersey-4 submarine cable (GJ4) is a high-speed fiber optic cable that connects the islands of Guernsey and Jersey in the English Channel. The cable is owned and operated by Guernsey Electricity and Jersey Electricity and was installed in 2015 to provide improved telecommunications services between the two islands.
The GJ4 cable is approximately 30 kilometers long and has a capacity of 100 gigabits per second, providing high-speed internet and data transmission services between the two islands. The cable was designed to enhance connectivity and support the growing demand for internet services, particularly in the areas of e-commerce, e-learning, and telemedicine.
The installation of the GJ4 cable was a collaborative effort between Guernsey Electricity, Jersey Electricity, and Alcatel-Lucent Submarine Networks, a leading provider of submarine cable systems. The project was completed on time and within budget, and the cable has been operational since its installation.
In addition to improving connectivity between the islands, the GJ4 cable has also contributed to the economic development of the region. By providing a reliable and high-speed internet connection, the cable has attracted new businesses and investment to the area, helping to create jobs and stimulate economic growth.
Overall, the Guernsey-Jersey-4 submarine cable is an essential piece of infrastructure that has improved connectivity and supported economic development in the English Channel region.
