[0037] The following takes the input optical packet signal as an example of 2.5Gb / s optical label and 100Gb / s payload:
[0038] 1. Device selection
[0039] In the QDSOA-based optical label and payload separator of the present invention, the key components are selected as follows:
[0040] 1) Selection of QDSOA: the central working wavelength of QDSOA is 1550nm;
[0041] 2) Selection of the second wavelength division multiplexer WDM2: λ 1 1550nm, λ 2 1570nm;
[0042] 3) Selection of semiconductor laser LD: the center wavelength is 1570nm;
[0043] 4) Selection of low-pass filter LPF: the cut-off frequency is 2.5GHz.
[0044] 2. Build optical tags and payload separators
[0045] according to figure 1 And related descriptions, build optical tags and payload separators.
[0046] 3. Working parameter setting
[0047] The main working parameters of the optical tag and payload separator are set as shown in Table 1. The optical tag is modulated by 2.5Gb / s non-return-to-zero ...
