S-, C- and L-band Raman counter-pump modules

Multi-wavelength Raman pumping for gain and power-tilt control across extended signal bands.

  • 1390, 1405 and 1430 nm pump lines
  • 1460-1610 nm signal passband
  • Power limits apply per wavelength

The listed pump powers apply to individual pump wavelengths. The signal passband and supervisory wavelength describe different optical paths and should not be treated as the pump wavelengths.

Configuration options

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

Conditions and configuration notes

  • A value in dBm describes optical power; a value in dB describes gain, loss or an optical budget. A link budget is not a distance in kilometres.
  • Performance depends on channel loading, fibre losses and the selected operating point; family limits do not automatically apply together.
  • The 40 dB supervisory-channel budget is stated with the Raman pumps off and span loss evaluated at 1624 nm.
