Protection In DWDM System: -<br />
06. CONS OF DWDM<br />
DWDM link can be designed to provide either p<strong>at</strong>h switched protection (two fiber working) or<br />
bi-directional line switched protection (four fiber working). The equipment protection can also<br />
be provided by using additional set of equipment. The protection facility is not available in the<br />
equipment being deployed in telecom network. In case of failure, the protection system of SDH<br />
ring will take care of the fault.<br />
