DWDM grid comb light sources

Spectrally sliced broadband light with selectable channel spacing on the ITU grid.

  • 50 GHz or 100 GHz channel spacing
  • 22 dBm listed output
  • Unpolarized optical output

Use the required band, spacing and number of channels to define a comb-source configuration. A grid-sliced source is not being described as a phase-coherent frequency comb.

Configuration options

Each row is a separate configuration. Limits from different rows must not be combined.

Conditions and configuration notes

  • The description lists up to 100 channels at 50 GHz spacing. Confirm channel count, band edges and per-channel spectral density for the chosen unit.
  • The 22 dBm entry is not assigned to each individual channel.

Applications to discuss

  • DWDM component testing
  • Optical network emulation
