• Passive cascade of interferential filters perform the channel add and drop functions.
• Two software-controlled VOAs in the add section, one for each add port, regulate the optical power
of inserted channels.
• Software-controlled VOAs regulate insertion loss on express channels.
• VOA settings and functions, photodiode detection, and alarm thresholds are internally controlled.
• Virtual photodiodes (firmware calculation of port optical power) at the common DWDM output and
input ports are monitored within the software.
