    en.wikipedia.org/wiki/Google_Fiber

    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]

  3. Reconfigurable optical add-drop multiplexer - Wikipedia

    en.wikipedia.org/wiki/Reconfigurable_optical_add...

    In optical communication, a reconfigurable optical add-drop multiplexer (ROADM) is a form of optical add-drop multiplexer that adds the ability to remotely switch traffic from a wavelength-division multiplexing (WDM) system at the wavelength layer.

  4. Fiber tapping - Wikipedia

    en.wikipedia.org/wiki/Fiber_tapping

    Tapping of optical fiber allows diverting some of the signal being transmitted in the core of the fiber into another fiber or a detector. Fiber to the home (FTTH) systems use beam splitters to allow many users to share one backbone fiber connecting to a central office, cutting the cost of each connection to the home. Test equipment can simply ...

  5. Add-drop multiplexer - Wikipedia

    en.wikipedia.org/wiki/Add-drop_multiplexer

    An add-drop multiplexer. An add-drop multiplexer (ADM) is an important element of an optical fiber network. A multiplexer combines, or multiplexes, several lower-bandwidth streams of data into a single beam of light.

  6. Fibre Channel - Wikipedia

    en.wikipedia.org/wiki/Fibre_Channel

    Fibre Channel director with SFP+ modules and LC optical fiber connectors with Optical Multimode 3 (OM3) fiber (aqua) Fibre Channel switches can be divided into two classes. These classes are not part of the standard, and the classification of every switch is a marketing decision of the manufacturer:

  7. Optical networking - Wikipedia

    en.wikipedia.org/wiki/Optical_networking

    Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks.These include limited range local-area networks (LAN) or wide area networks (WANs), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks.

  8. Fiber to the premises in the United States - Wikipedia

    en.wikipedia.org/wiki/Fiber_to_the_premises_in...

    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.

  9. Optical transport network - Wikipedia

    en.wikipedia.org/wiki/Optical_transport_network

    ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links, able to provide functionality of transport, multiplexing, switching, management, supervision and survivability of optical channels carrying client signals. [1]
