Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
In WDM technology, the light signal of the different wave length be coupled is referred to as optical wavelength passage; And by optical wavelength passage from multiplexing one end, to being terminated one end of optical wavelength passage demultiplexing, an end-to-end link of formation is referred to as optical multiplexing section.
Embodiment 1
As shown in Figure 1, a kind of method setting up multichannel polyaluminium chloride PAC in dense wavelength division network, comprises the following steps:
Step S1, obtains the optical wavelength schedule information of multiple optical multiplexing section and each optical multiplexing section;
The acquisition obtaining optical multiplexing section in above-mentioned steps has various ways, and the general obtain manner of optical multiplexing section and its optical wavelength schedule information is described for typical scene below:
Due under typical scene, optical multiplexing section is carried by optical transmission section, therefore will obtain optical multiplexing section and just first must obtain optical transmission section;
Optical transmission section is directly connected by optical fiber by the optical transport light mouth of a pair transmitting-receiving.Optical transport Guang Kou, conjunction glistening light of waves mouth and a point glistening light of waves mouth directly can be determined by board type coding, and then are optical transport light mouth by the optical interface type judging Fiber connection two ends, just can obtain optical transmission section.
If the wherein one or both ends of optical fiber are the extra long distance amplifying unit of raman amplifier or remote optical pumping amplifier and so on, then can extend in turn along the tail optical fiber of raman amplifier or remote optical pumping amplifier and find, until find optical transport light mouth, namely find optical transmission section.
After finding optical transmission section, determine to exist with optical transport light mouth according to the hardware specification of board the light mouth that optical multiplexing section is fixedly connected with, and be starting point by there is with the optical transport light mouth at optical fiber two ends the light mouth that optical multiplexing section is fixedly connected with, and then extend in turn along the tail optical fiber on this light mouth, until find optical multiplexing section light mouth.
When optical multiplexing section light mouth is all found at the two ends of optical transmission section, then this forms an optical multiplexing section to optical multiplexing section light mouth.
The obtain manner of optical wavelength schedule information is as follows:
The acquisition of Wavelength dispatching information comprises two kinds of situations: the first is that in this case, Wavelength dispatching information depends on the Fiber connection between optical add/drop multiplexer for fixing optical add/drop multiplexer; The second is for can the optical add/drop multiplexer of reprovision, and in this case, Wavelength dispatching information is made up of the Fiber connection between the configuration-direct of optical add/drop multiplexer and add-drop multiplexer;
For fixing optical add/drop multiplexer, be specially and determine to close a point glistening light of waves mouth H1 according to the specification of board, close point glistening light of waves mouth and the wavelength channel signal annexation up and down between glistening light of waves mouth L1; The mouth of the glistening light of waves up and down at the wavelength channel signal place that the characteristic frequency of conjunction glistening light of waves mouth demultiplexing is corresponding is determined according to above-mentioned annexation; Then the direction of wavelength channel signal is traced into according to Fiber connection one step of upper and lower glistening light of waves mouth; When having accessed the receiver of a wavelength channel above on the direction of the wavelength channel signal found, then think to only have to close and divide wavelength channel corresponding on glistening light of waves mouth H1 occupied; If accessed another to close the mouth of the glistening light of waves up and down H2 corresponding to point glistening light of waves mouth H2, then think that the wavelength channel closing point glistening light of waves mouth H1 and H2 corresponding is all occupied.
For configurable optical add/drop multiplexer, compared with above-mentioned fixing optical add/drop multiplexer, the difference of the deterministic process of its wavelength channel configuration information is: the wavelength channel signal annexation of closing between point glistening light of waves mouth and upper and lower glistening light of waves mouth is not determined by board specification, but dynamically determined by exterior arrangement, these configuration informations can be obtained by instructions query, substituting into fixing add-drop multiplexer processing procedure by inquiring about the configuration information obtained, the configuration information of wavelength channel can be obtained equally.Continue for aforementioned, closing acquiescence between point glistening light of waves mouth H1 to upper and lower glistening light of waves mouth L1 does not have wavelength channel signal to connect.On upper ripple direction, one group of optical wavelength signal arrives L1 light mouth simultaneously, and the wave frequency of this group optical wavelength signal can not exist repetition, and exterior arrangement instruction certain optical wavelength signal specified on L1 leads to a conjunction point glistening light of waves mouth H1.The process in lower ripple direction is similar, enters in all optical wavelength signals closing point glistening light of waves mouth H1, has an optical wavelength signal to be specified by instruction and is sent to L1 light mouth.The process of closing between point glistening light of waves mouth is identical with the process of fixed light add-drop multiplexer, optical wavelength signal on L1 light mouth is sent to another by Fiber connection and closes the mouth of the glistening light of waves up and down L2 corresponding to point glistening light of waves mouth H2, then completes the signal communication between L2 and H2 by configuration-direct.All the other processes and the first situation similar, do not repeat them here.
