The Huawei OSN3500 SSN2DCU supports dispersion compensation for up to two optical signals simultaneously. The dispersion compensation available is 680ps/nm (corresponding to the dispersion generated by 40km G.652 fiber), 1020ps/nm (corresponding to the dispersion generated by 60km G.652 fiber), or 1360ps/nm (corresponding to the dispersion generated by 80km G.652 fiber), or any combination of the three.
Huawei OSN3500 SSN2DCU Single Board Feature Code
The veneer characteristic code is the code located after the veneer name in the veneer barcode.The veneer characteristic code of the DCU is used to describe the amount of dispersion compensation of the optical signal.
The relationship between the veneer characteristic code of the DCU and the dispersion compensation amount is shown in Table 1.
