Product Description - Asymmetric Optical Interleaver

Conventional Optical Interleaver is Symmetric Optical Interleaver. By "Symmetric" we mean that both "Odd" and "Even" channels have the same passband widths and waveforms. Optoplex offers a new type of Optical Interleaver whose "Odd" and "Even" channels have different passband widths and waveforms. This is FlexSlicer™ Asymmetric Optical Interleaver.

Based on Optoplex’s patented technologies, FlexSlicer™ Asymmetric Optical Interleaver has superior passband and dispersion characteristics that are particularly suitable for 40-Gb/s data-rate. A major feature of the device is that customer has the freedom of specifying the ratio of the passband widths for Odd and Even channels for the two interleaving ports. FlexSlicer™ has passed the reliability testing based on Telcordia GR-1221 requirements.

Being the first of its kind, FlexSlicer™ Asymmetric Optical Interleaver has been developed specifically to help telecommunication carriers to ease the migration from low to high data-rate (2.5 ~ 10 Gb/s or 10 ~ 40 Gb/s). With the help of FlexSlicer™, low and high data-rate signals can coexist in the same infrastructure and utilize the same telecommunication equipment. The carriers can retain the current investment while introducing the high data-rate services with minimum incremental cost.

Parameter Definition of Optical Interleaver

Parameter Definition

 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

Definition of interleaver parameters

 

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
