In the field of optical fiber communication, the dispersion compensation module (DCM) (also known as the dispersion compensation unit, DCU) is used to compensate for the dispersion, for example, to compensate for the dispersion in a long transmission fiber. Usually, this module provides a certain amount of dispersion, but there are also modules with tunable dispersion. Inserting the module into th...

With the explosion of network data flow, 100G transmission has begun to be widely used. At present, the traditional 100G/200G coherent optical DWDM CFP/CFP2 transmission solution is expensive and has a long lead time;FIBERWDM Ruid Ele-tech has launched a non-coherent 100G DWDM QSFP28 transmission solution through various efforts and cooperation, which has a good cost advantage in 100G short-distan...

    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...
