Google Fiber, sometimes stylized as GFiber, is a fiber broadband Internet service operated by Google Fiber Inc., [2] a subsidiary of Alphabet, [3] servicing a growing number of households in cities in 19 states across the United States. [4] In mid-2016, Google Fiber was estimated to have about 453,000 broadband customers. [5]
With its U-verse product, AT&T (formerly SBC) had pursued a strategy of Fiber to the Neighborhood (FTTN) and had even delivered Fiber to the Premises (FTTP) prior to the services' launch. Currently, U-verse is deployed as a Fiber to the Hub (FTTH) service; the line connecting the hub to the home is a dual copper pair line.
The most common types that are added to fiber optic cable in inside plant environments are LC, SC, ST, and FC. Some fiber connectors are pre-polished mechanical connectors for ease of installation or anaerobic connectors which require cleaving and polishing. [1] Once the appropriate connector has been identified, the termination process can begin.
Cable jetting is the process of blowing a cable through a duct while simultaneously pushing the cable into the duct. Compressed air is injected at the duct inlet and flows through the duct and along the cable at high speed.
(fiber-to-the-screen or -seat): On an airplane, fiber reaches the IFE screens (fiber-to-the-street): The customer is connected using copper to the fiber passing near the building, up to 200 m (700 ft) away. This is a compromise between FTTB and FTTC. Typically providing up to 500 Mbit/s (fiber-to-the-subscriber): This is a synonym for FTTP

The process of communicating using fiber optics involves the following basic steps: creating the optical signal involving the use of a transmitter, [9] usually from an electrical signal; relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak; receiving the optical signal; converting it into an ...
An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications .
