Chapter 1 Applications
ONS 15216 EDFA1 Operation
• Low-noise figure of < 6.0 dB
Constant Gain Mode
Constant amplification per wavelength is important for bandwidth-on-demand wavelength services. As
wavelengths are added/dropped from an optical fiber, small variations in gain between channels in a
span can cause large variations in the power difference between channels at the receivers. The
ONS 15216 EDFA1 enables bandwidth-on-demand services by guaranteeing that every wavelength is
amplified by 23 dB, regardless of the number of wavelengths being amplified.
Constant gain mode is achieved using an automatic control circuit that adjusts pump power when
changes in input power are detected. The ONS 15216 EDFA1 operates in constant gain mode by default,
but because other operating modes can be required, the EDFA can also be set to operate in any one the
following modes:
• Constant-pump current mode
• Constant-pump power mode
• Constant-output power mode
Gain Flatness
Figure 1-2 illustrates the importance of the ONS 15216 EDFA1’s gain-flattening filter. With the first
fiber (a), channels having equal power going into a cascaded network of amplifiers have vastly different
powers and optical signal-to-noise ratio (SNR) at the output—without a gain flattening filter. In contrast,
with the second fiber (b), the EDFAs reduce this effect by introducing a gain-flattening filter within each
amplifier

Transient Suppression
Transients in the performance of EDFAs are inevitable whenever the number of signals or the relative
power of signals change. The amount of time required by an amplifier to recover from a change indicates
the suitability of the amplifier for add/drop applications.
