  2. Optical ground wire - Wikipedia

    en.wikipedia.org/wiki/Optical_ground_wire

    OPGW as a communication medium has some advantages over buried optical fiber cable. Installation cost per kilometre is lower than a buried cable. Effectively, the optical circuits are protected from accidental contact by the high voltage cables below (and by the elevation of the OPGW from ground).

  3. Optical power budget - Wikipedia

    en.wikipedia.org/wiki/Optical_power_budget

    The optical power budget (also fiber-optic link budget and loss budget) in a fiber-optic communication link is the allocation of available optical power (launched into a given fiber by a given source) among various loss-producing mechanisms such as launch coupling loss, fiber attenuation, splice losses, and connector losses, in order to ensure that adequate signal strength (optical power) is ...

  4. Backhaul (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Backhaul_(telecommunications)

    Wireless backhaul is easy to deploy, cost efficient and can provide high capacity connectivity, e.g., multiple gigabits per second, and even tens of Gbps. Wireline fiber backhaul, on the other hand, can provide practically endless capacity, but requires investment in deploying fiber as well as in optical equipment.

  5. Link budget - Wikipedia

    For example, a "2 by 4" wood stud wall with drywall on both sides results in about 6 dB loss per wall at 2.4 GHz. [2] Older buildings may have even greater internal losses than new buildings due to materials and line of sight issues. Experience has shown that line-of-sight propagation holds only for about the first 3 meters.

  6. Optical attached cable - Wikipedia

    en.wikipedia.org/wiki/Optical_attached_cable

    SkyWrap fibre-optic cable installation Optical attached cable ( OPAC ) is a type of fibre-optic cable that is installed by being attached to a host conductor along overhead power lines . The attachment system varies and can include wrapping, lashing or clipping the fibre-optic cable to the host.

  7. Fiber to the x - Wikipedia

    en.wikipedia.org/wiki/Fiber_to_the_x

    Fiber to the x (FTTX; also spelled "fibre") 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 ...

  9. Last mile (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Last_mile_(telecommunications)

    The word "mile" is used metaphorically; the length of the last mile link may be more or less than a mile. Because the last mile of a network to the user is conversely the first mile from the user's premises to the outside world when the user is sending data, the term first mile is also alternatively used.
