Embodiment Construction

[0021] Below, we illustrate the content of the present invention through an example.

[0022] The information wavelength of the optical burst switching system is selected as 8 channels.

[0023] The control wavelength is selected as 1310nm, and the information wavelength is selected as the DWDM wavelength with 1550nm as the center of the ITU standard. The wavelength interval is 200GHz. The specific data is shown in Figure 3. According to the method provided by the present invention, a corresponding optical burst switching system can be obtained, and its optical path diagram is shown in FIG. 4 .

[0024] Experiments with the optical burst switching system shown in Figure 4 can meet the requirements of OBS system performance and optical signal transmission quality, and greatly reduce the cost of the optical burst switching system and save information wavelength channel resources.

Abstract

The invention provides a designing method for the light bursting exchange control wavelength, Both the control wavelength and the message wavelength of the typical light bursting exchange system take 1550nm as the ITU standard DWDM wavelength. The invention takes 1310nm as the control wave length and 1550nm as the message wave length, and selects 1310 / 1550 broad band wave multiplier to multiply and inverse multiply the control wavelength and the total message wavelength to realize the light transmission of the light bursting exchange system.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular relates to a design method of control and information channel wavelength in an optical burst switching system. Background technique [0002] The speed of the optical fiber network backbone is increasing rapidly, so the requirements for the processing power of routers and switches are also increasing. Due to the bottleneck of electrical processing in traditional electrical switching, three new solutions have been proposed for how to implement switching and transmission in optical networks: Optical Wavelength Switching (OλS), Optical Burst Switching (OBS), and Optical Burst Switching (OBS). ), Optical Packet Switching (Optical Packet Switching, OPS). Optical burst switching is an intermediate solution, which combines the advantages of OλS and OPS, and overcomes their shortcomings. It is a very promising optical switching mode. [0003] In the OBS network, a b...
