2. Fiber-optic communication - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_communication

   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]

3. Router (computing) - Wikipedia

   en.wikipedia.org/wiki/Router_(computing)

   Router (computing) Rack containing a service-provider–class router connected to multiple networks. A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [2] [3] [4] A router is connected to two or more data lines from different IP networks.

4. Modem - Wikipedia

   en.wikipedia.org/wiki/Modem

   v. t. e. A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to ...

5. Single-mode optical fiber - Wikipedia

   en.wikipedia.org/wiki/Single-mode_optical_fiber

   In fiber-optic communication, a single-mode optical fiber ( SMF ), also known as fundamental- or mono-mode, [1] is an optical fiber designed to carry only a single mode of light - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell's equations and the boundary conditions.

6. Fiber media converter - Wikipedia

   en.wikipedia.org/wiki/Fiber_media_converter

   Fiber media converter. A fiber media converter is a simple networking device that makes it possible to connect two dissimilar media types such as twisted pair with fiber optic cabling. They were introduced to the industry in the 1990s, and are important in interconnecting fiber optic cabling-based systems with existing copper-based structured ...

7. Fiber to the x - Wikipedia

   en.wikipedia.org/wiki/Fiber_to_the_x

   Fiber to the x is the key method used to drive next-generation access ( NGA ), which describes a significant upgrade to the broadband available by making a step change in speed and quality of the service. This is typically thought of as asymmetrical with a download speed of 24 Mbit/s plus and a fast upload speed. [2]
