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.
In telecommunications, broadband or high speed is the wide-bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Internet access. The transmission medium can be coaxial cable, optical fiber, wireless Internet (radio), twisted pair cable, or satellite.
Internet access is a facility or service that provides connectivity for a computer, a computer network, or other network device to the Internet, and for individuals or organizations to access or use applications such as email and the World Wide Web. Internet access is offered for sale by an international hierarchy of Internet service providers (ISPs) using various networking technologies. At the retail level, many organizations, including municipal entities, also provide cost-free access to the general public.

A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. In this use, a PON has a point-to-multipoint topology in which an ISP uses a single device to serve many end-user sites using a system such as 10G-PON or GPON. In this one-to-many topology, a single fiber serving many sites branches into multiple fibers through a passive splitter, and those fibers can each serve multiple sites through further splitters. The light from the ISP is divided through the splitters to reach all the customer sites, and light from the customer sites is combined into the single fiber. Many fiber ISPs prefer this system.
Gerard A. Alphonse is a Haitian electrical engineer, physicist and research scientist, and was the 2005 president of the United States division of the Institute of Electrical and Electronics Engineers (IEEE). He has served on several of IEEE's committees and boards.
C Spire, formerly known as Cellular South, Inc., is a privately owned telecommunications and technology company headquartered in Ridgeland, Mississippi. The company consists of three business divisions – Wireless, Home Fiber, and Business.
An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss and are immune to electromagnetic interference. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, such as fiber optic sensors and fiber lasers.
Phonoscope Communications is a broadband and communications provider with corporate headquarters in Houston, Texas. The company's infrastructure spans eight counties and reaches distant locations such as Baytown, Galveston, Freeport, Magnolia, Richmond-Rosenberg, Splendora, Texas City and Willis, Texas.
Frontier Communications Parent, Inc. is an American telecommunications company. Known as Citizens Utilities Company until 2000, Citizens Communications Company until 2008, and Frontier Communications Corporation until 2020, as a communications provider with a fiber-optic network and cloud-based services, Frontier offers broadband internet, digital television, and computer technical support to residential and business customers in 25 states. In some areas it also offers home phone services.
The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices. It is complemented by the MAC layer and the logical link layer. An implementation of a specific physical layer is commonly referred to as PHY.
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.
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 fiber-optic communication in different applications, for example long-distance telecommunication or providing a high-speed data connection between different parts of a building.
The Internet in the United States grew out of the ARPANET, a network sponsored by the Advanced Research Projects Agency of the U.S. Department of Defense during the 1960s. The Internet in the United States in turn provided the foundation for the worldwide Internet of today.
Grande Communications Networks, LLC is an American telecommunications company, based in San Marcos, Texas, that uses a fiber optic and cable network to offer broadband services. The company was established in 1999 when it was the recipient of the largest round of venture capital funding in Texas. Grande delivers internet access, local and long-distance telephone service and digital cable over its own network to nine different markets in Texas. Grande Communications serves as the primary provider of cable services for dormitories on the campuses of Texas State University, University of the Incarnate Word, Baylor University and the University of Texas at Austin. It is controlled by private equity firm TPG Capital through its affiliate Patriot Media Consulting. Grande Communications is available to an estimated 1.1 million people, making it the 16th largest provider of cable broadband in the U.S. by coverage area.
