Extinction Ratio
Extinction ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage. Extinction ratio = P1/P0

Receiver
A receiver is a detector and electronic circuitry to change optical signals into electrical signals.

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
