Fiber Dispersion Control

Dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency (wavelength). It is sometimes called chromatic dispersion due to the wavelength dependency nature. This issue becomes prominent for higher data rate (shorter pulse width) as well as longer transmission distance.

LDCM DISPERSION COMPENSATION MODULE

Other than fiber link attenuation, dispersion is another major factor which limits the transmission distance of 1550nm band of optical fiber system, particularly for long haul transmissions. Lightem LDCM series dispersion compensation fiber module, is negative dispersion compensation based on optical fiber technology, can effectively compensate for G.652 standard single-mode fiber transmission band of 1525 ~ 1565nm dispersion and dispersion slope characteristic.
