| http://www.w3.org/ns/prov#value | - At Step 413, a respective communication signal modulates the multimode light of each laser device for each DWDM channel 151, 152, 153, 15N. This modulating communication signal is typically an electrical data signal in digital format, but can also be an analog electrical signal, optical signal, or other signal that can cause optical modulation of the multimode light.
