DCM- Dispersion Compensation Module
Jun 05 , 2024
In fiber communication, optical pulses extend due to dispersion and tend to overlap with adjacent pulse periods. This causes interference between adjacent bits and leads to a high BER.At a high bit rate equal to the pulse width, the bit error rate (due to dispersion) will become too large.The dispersion compensation module (DCM) (also known as the dispersion compensation unit, DCU) c...
