Application of CWDM boards on OSN 1800

27

In the case of a CWDM and DWDM hybrid network, the 1531 nm and 1551 nm wavelengths in the CWDM system must be reserved for the expansion to the DWDM system. The optical ports for the 1531 nm and 1551 nm wavelengths can be extended to access 10 and 16 DWDM wavelengths respectively. That is, a total of 26 DWDM wavelengths can be extended.
