A terrestrial cable is a communications cable which crosses land, rather than water. Terrestrial cable may be subterranean (buried) or aerial (suspended from poles), and may be fiber or copper. [1] [2] The term "terrestrial cable" is principally used to distinguish it from submarine cable, [3] although some overlap exists between the two. [4]
Major terrestrial cable systems include the Europe-Persia Express Gateway and the family of Eurasia terrestrial cable networks. [5] [6] [7]

In telephony, the local loop is the physical link or circuit that connects from the demarcation point of the customer premises to the edge of the common carrier or telecommunications service provider's network.
Telecommunications in Armenia involves the availability and use of electronic devices and services, such as the telephone, television, radio or computer, for the purpose of communication. The various telecommunications systems found and used in Armenia includes radio, television, fixed and mobile telephones, and the internet.
Fiber to the x or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber.
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.
Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching systems, and other plain old telephone service facilities, optical fiber cabling, IP networks, and microwave transmission systems. Telecommunications engineering also overlaps with broadcast engineering.
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for optical communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building.
Telecommunications in Guyana include radio, television, fixed and mobile telephones, and the Internet. Early telecommunications were owned by large foreign firms until the industry was nationalized in the 1970s. Government stifled criticism with a tight control of the media, and the infrastructure lagged behind other countries, Guyana Telephone and Telegraph Company (GT&T) holding a monopoly on most such services. In a 2012 census report on Guyanese households, 55.5% had a radio, 82.7% had a television, 27.8% had a personal computer, and 16.2% had internet at home, 49.3% had a telephone landline, and 70.6% had a cellular phone.
Telecommunications in Angola include telephone, radio, television, and the Internet. The government controls all broadcast media with a nationwide reach.
Telecommunications in Ivory Coast include radio, television, fixed and mobile telephones, and the Internet.
Phase 3 Telecom is an aerial fiber-optic network infrastructure provider, providing connectivity, network management, and data storage services to wholesale, enterprise, and retail customers across West Africa. The company was incorporated in 2003 and is headquartered in Abuja, Nigeria. Licensed by the Nigerian Communications Commission in 2006 - the company in 2014, 2018, and 2022, added more kilometers to its existing coverage area with footprint expansion of its backbone, enterprise network, and broadband services. Phase operates 6,000 kilometres (3,700 mi) and counting open-access aerial fiber-optic network. The company, for over two decades has been vital to growth in Africa's growing ICT market, implementing the Wire Nigeria Project—conceived by the Nigerian Communications Commission to help provide broadband communications access to rural communities. Phase 3 has a broad range of wholesale and enterprise clients including Glo, MTN, 9Mobile, Ntel, Airtel, Smile Communications, World Bank, Julius Berger, Unity Bank, etc. Some of the African countries where the company currently has partner operations include Nigeria, Benin, Togo, and the Republic of Niger.
MAREA is a 6,605 km long transatlantic communications cable connecting the United States with Spain. Owned and funded by Microsoft and Meta Platforms, but constructed and operated by Telxius, a subsidiary of the Spanish telecom company Telefónica, it is the "highest-capacity submarine cable in the world" with a system design capacity of 200 terabits per second as of 2019.
G.657 is an international standard developed by the Standardization Sector of the International Telecommunication Union (ITU-T) that specifies single-mode optical fiber (SMF) cable.
G.651.1 is an international standard developed by the Standardization Sector of the International Telecommunication Union (ITU-T) that specifies multi-mode optical fiber (MMF) cable.
