Extinction Ratio Calculation Formula for Optical Transmitters

Extinction ratio shows how well a system tells strong signals from weak ones. Extinction ratio, when used to describe the performance of an optical transmitter used in digital communications, is simply the ratio of the energy (power) used to transmit a logic level '1', to the energy used to transmit a logic level '0'. For a graphical description, the eye-diagram is commonly. Eye diagram showing an example of two power levels in an OOK modulation scheme, which can be used to calculate extinction ratio.

Transnational Optical Cable Transmission Rate

Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on (SONET). Transmission rates are defined by rate of the of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84. Thus, the speed of optical-carrier-classified lines labeled as OC-n is.
