2. Wavelength selective switching - Wikipedia

   en.wikipedia.org/wiki/Wavelength_Selective_Switching

   This provides cost and performance benefits for next generation colorless, directionless, contentionless (CDC) reconfigurable optical add-drop multiplexer (ROADM) networks, resulting from improved scalability of add/drop ports and removal of erbium-doped fiber amplifier (EDFA) arrays (which are required to overcome splitting losses in multicast ...

3. Optical fiber - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber

   These fiber optic coating layers are applied during the fiber draw, at speeds approaching 100 kilometers per hour (60 mph). Fiber optic coatings are applied using one of two methods: wet-on-dry and wet-on-wet. In wet-on-dry, the fiber passes through a primary coating application, which is then UV cured, then through the secondary coating ...

4. Polarization-maintaining optical fiber - Wikipedia

   en.wikipedia.org/wiki/Polarization-maintaining...

   The output of a PM fiber is typically characterized by its polarization extinction ratio (PER)—the ratio of correctly to incorrectly polarized light, expressed in decibels. The quality of PM patchcords and pigtails can be characterized with a PER meter. Good PM fibers have extinction ratios in excess of 20 dB.

Cable assembly containing one or more optical fibers that are used to carry light A TOSLINK optical fiber cable with a clear jacket. These cables are used mainly for digital audio connections between devices. A fiber-optic cable, also known as an optical-fiber cable, is an assembly ...

6. Multi-mode optical fiber - Wikipedia

   en.wikipedia.org/wiki/Multi-mode_optical_fiber

   The equipment used for communications over multi-mode optical fiber is less expensive than that for single-mode optical fiber. [1] Typical transmission speed and distance limits are 100 Mbit/s for distances up to 2 km (), 1 Gbit/s up to 1000 m, and 10 Gbit/s up to 550 m.

7. Fiber-optic communication - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_communication

   Fiber-optic communication is a form of optical communication for 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 ]

9. Radio over fiber - Wikipedia

   en.wikipedia.org/wiki/Radio_over_fiber

   Electrical RF is directly connected to a TV or set-top box. 1550 nm is more popular because it has less losses in the fiber and by using fiber-optic amplifier known as EDFA it is possible to extend the transport distance. 1310 nm loses about 0.35 dB/km of optical signal, 1550 nm loses only 0.25 dB/km. Optical budget between transmitter and ...
