OTN DCM Dispersion Compensation Module Implemented For Lines 20 PS/ Nm•Km
The FONST 3000 provides the DCM module, which can compensate for the dispersion caused transmission performance degradation.
The DCM (Dispersion Compensation Module) can compensate the optical signal dispersion accumulated during the transmission process in the fiber and suppress the optical signal pulse, so as to resume the optical signal. It is used together with the optical amplification card to implement the long-haul optical regeneration transmission.
The optical line with a rate of 10 Gbit/s or above is sensitive to dispersion. Dispersion compensation should be implemented for lines whose length is more than a certain value. Users can choose compensation schemes according to the following tables (the G.652 fiber chromatic dispersion is 20 ps/ nm•km).
| Module Type | Typical Compensation Distance (km) | Maximum Insertion Loss (dB) | Dispersion Slope Compensation Rate | PMD (ps) | Polarization Dependent Loss (dB) | Maximum Input Power Allowed (dBm) | Operating Wavelength Range (nm) |
