2. 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.

3. Optical fiber - Wikipedia

   en.wikipedia.org/wiki/Optical_fiber

   At optical intensities above 2 megawatts per square centimeter, when a fiber is subjected to a shock or is otherwise suddenly damaged, a fiber fuse can occur. The reflection from the damage vaporizes the fiber immediately before the break, and this new defect remains reflective so that the damage propagates back toward the transmitter at 1–3 ...

4. 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]

5. 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.

6. 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.
