  此可切換光學梳狀分波/合波器有兩種操作模式:

  ● 模式A:全通

  ● 模式B:光學梳狀分波/合波器

  當器件處于模式A時,系統中的所有通道(可以是任何通道間隔)經過模塊的輸入端和一個輸出端,就如沒有器件插入一樣。當器件切換到模式B時,模塊即成為一個標準的對稱光學梳狀分波器(或也可以是非對稱光學梳狀分波器),其工作原理示意圖如下所示。通道間隔不限制在50-100GHz,可由用戶指定。它們可以在任何頻率之間:N-GHz到2N-GHz。

 Parameter Definition of Optical Interleaver

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
