Parameter Definition
Example
Wavelength Range (nm) is the spectral range over which the optical interleaver's opticalperformance can be met.
1530.33 - 1563.05 nm
Insertion Loss (dB) is the relative power level transmitted to the output ports referenced to the 0-dB level when the optical interleaver is inserted. It is the power difference between the 0-dB level and the minimum power level measured within a given passband window. See figure below.
1.5 dB
Ripple (dB) is defined as the power difference between the minimum loss and the maximum loss within a given passband.
0.3 dB
Passband Bandwidth (GHz) is defined as the spectral width centered at ITU grid at a given power level, typically at 0.5 dB below the minimum insertion loss point.
ITU ± 30 GHz
Isolation (dB) is defined as the power difference between maximum insertion loss measured within a given passband window and the minimum insertion loss measured within the adjacent stopbandwindow
24 dB
Insertion Loss Uniformity (dB) is the difference between the maximum insertion loss and minimum insertion loss over all channels, either within one output port or both ports.
0.3 dB
Polarization Dependent Loss (PDL) (dB) is the difference between the maximum and minimum insertion loss over all polarization states within a given passband window.
0.3 dB
Chromatic Dispersion (CD) (ps/nm) is the derivative of the Group Delay versus wavelength within a given passband width.
24 ps/nm within ITU±20%FSR
Polarization Mode Dispersion (PMD) (ps) is the maximum Differential Group Delay within a givenpassband width.
0.2 ps within ITU±30%FSR
Optical Return Loss (dB) is the ratio between the input power and the reflected power over all polarization states at each port , RL = -10×log10(Pr/Pin).
40 dB
Operating Temperature (°C) is the ambient temperature range over which the device's performance spec can be met.
-5 to 65 °C
Storage Temperature (°C) is the ambient temperature range over which the device can be stored without affecting its intended application afterwards.
-40 to 85 °C
