WebWhat is the frequency range of optical Fibre? 10 14 to 10 15 Hz The light sent down the fiber-optic cable corresponds to an electromagnetic wave with a frequency in the range of 10 14 to 10 15 Hz. As mentioned already, the system appears capable of sending information at rates of 10 14 bits/s. What is optical frequency? WebThe free spectral range of an optical resonator ( cavity) is the spacing of its axial (Gaussian-shaped) resonator modes in terms of optical frequency . It is also called axial mode spacing . For an empty standing-wave resonator of length L, it can be calculated as. For a ring resonator, the factor of 2 is removed, since there is no double pass.
