2. 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 ...

3. Link budget - Wikipedia

   en.wikipedia.org/wiki/Link_budget

   A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver.

4. Cutback technique - Wikipedia

   en.wikipedia.org/wiki/Cutback_technique

   A variation of the cutback technique is the substitution method, in which measurements are made on a full-length of fiber, and then on a short length of fiber having the same characteristics (core size, numerical aperture), with the results from the short length being subtracted to give the results for the full length.

5. Extinction ratio - Wikipedia

   en.wikipedia.org/wiki/Extinction_ratio

   Eye diagram showing an example of two power levels in an OOK modulation scheme, which can be used to calculate extinction ratio. P 1 and P 0 are represented by (binary 1) and (binary 0) respectively. In telecommunications, extinction ratio (r e) is the ratio of two optical power levels of a digital signal generated by an optical source, e.g., a ...

6. 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 ...

7. List of optics equations - Wikipedia

   en.wikipedia.org/wiki/List_of_optics_equations

   Subscripts 1 and 2 refer to initial and final optical media respectively. These ratios are sometimes also used, following simply from other definitions of refractive index, wave phase velocity, and the luminal speed equation:

9. Optical power margin - Wikipedia

   en.wikipedia.org/wiki/Optical_power_margin

   The optical power margin is usually expressed in decibels (dB). At least several dB of optical power margin should be included in the optical power budget . The amount of optical power launched into a given fiber by a given transmitter depends on the nature of its active optical source ( LED or laser diode ) and the type of fiber, including ...
