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. [1] [2] The light is a form of carrier wave that is modulated to carry information. [3]
Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. [2] Thus, the speed of optical-carrier-classified lines labeled as OC-n is n × 51.84 Mbit/s.
19165 (Webpass) 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.
Internet speed. As of January 2019 in Addis Ababa there are 2G/3G and 4G (Ethiopian Telecommunication) connection options. Despite the availability of 4G sim & connections speed for a mobile connection hardly reach 3 Mbit/s of download speed, and 1 Mbit/s for upload (average 1.5 Mbit/s download, 0.3 Mbit/s upload).
Fiber-optic communication remains the medium of choice for Internet backbone providers for several reasons. Fiber-optics allow for fast data speeds and large bandwidth , they suffer relatively little attenuation , allowing them to cover long distances with few repeaters , and they are also immune to crosstalk and other forms of electromagnetic ...
An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] 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 (data transfer rates) than electrical cables.
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 ...
Internet connections in the United States are largely provided by the private sector and are available in a variety of forms, using a variety of technologies, at a wide range of speeds and costs. In 2000, a majority of U.S. households had at least one personal computer and internet access the following year. [1]
