17.1.7 OSC Regeneration Node
The OSC regeneration node is added to the DWDM networks for two purposes:
• To electrically regenerate the OSC channel whenever the span links are 37 dB or longer and payload
amplification and add/drop capabilities are not present. Cisco MetroPlanner places an OSC
regeneration node in spans longer than 37 dB. 31 dB is the longest span between the OSC
regeneration node and the next DWDM network site.
• To add data communications network (DCN) capability wherever needed within the network.
OSC regeneration nodes require two OSC-CSM cards, as shown in Figure 17-13.
