Applications of O-Band Interleaver for 5G-PON Mux/DeMux

DWDM PON is the choice of 5G PON for the front-haul optical links. For 50GHz grid DWDM for O-band, particularly for outdoor applications where the required operating temperature range from -40oC to +85oC, optical interleaver plus 100GHz thin film filter DWDM is the best solution due to its high performance and excellent temperature stability.

 Example

Wavelength Range (nm) is the spectral range over which the optical interleaver's optical performance 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 stopband window

24 dB

Parameter definition of Optoplex interleaver

 

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 given passband 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
