S101, forward adjustment is carried out to the luminous power of the first optical conversion element OMS section;
S102, basis regulate the forward that the luminous power of an OMS section is carried out, and oppositely regulate the luminous power of the 2nd OMS section, the 2nd OMS section is the downstream OMS section of an OMS section in optical-fiber network.
The optical signal power control method that the embodiment of the present invention provides, be applicable to existing various types of optical-fiber network, as shown in Figure 2, Fig. 2 provides the structural representation of a kind of optical-fiber network that the embodiment of the present invention is suitable for, multiple OTU transmitting terminal can be comprised in this optical-fiber network, the multipath light signal that multiple OTU transmitting terminal sends is switched via wavelength selectivity and is closed ripple plate (WavelengthSelectiveSwitchingMultiplexingBoard, WSM) a road light signal is synthesized after, light signal is after several OMS sections, partial wave plate (WavelengthSelectiveSwitchingDemultiplexingBoard is switched again through wavelength selectivity, WSD) multipath light signal corresponding with transmitting terminal is divided into after, input to multiple OTU receiving terminal respectively.Usually several Reconfiguration Optical Add/drop Multiplexer unit (Reconfigurationopticaladd/dropmultiplexer can be comprised between the WSM of transmitting terminal and the WSD of receiving terminal, ROADM), each ROADM unit can comprise image intensifer, WSD and WSM usually.
Wherein, the OMS section related in the embodiment of the present invention, such as: an OMS section and the 2nd OMS section, generally include optical amplifier part, WSD and WSM, optical amplifier part can comprise image intensifer (OpticalAmplifier, OA) and Variable Optical Attenuator Unit (variableopticalattenuatorboard, VOA).First OMS section in optical-fiber network, can be the WSD input port of WSM delivery outlet to next ROADM of first ROADM usually, that is, the multiplexing veneer delivery outlet of business input and output, to the demultiplexing veneer input port of next business input and output.Optical-fiber network shown in Fig. 2 comprises 3 sections of OMS, is respectively OMS1, OMS2 and OMS3, the concrete dividing mode of each OMS section see Fig. 2, but not in this, as the restriction to the embodiment of the present invention.
It should be noted that, the OMS section related in the embodiment of the present invention not refers in particular to first OMS section in optical-fiber network, and any OMS section in optical-fiber network can be referred to, but usually can refer to the upstream OMS section in optical-fiber network, so-called upstream OMS section, be for receiving terminal OTU, closer to the OMS section of transmitting terminal OTU.2nd OMS section refers to the downstream OMS section of an OMS section, that is, relative to an OMS section, the 2nd position of OMS section in optical-fiber network is closer to receiving terminal OTU.And the 2nd OMS section can be the downstream OMS section adjacent with an OMS section, also can be and an OMS section non-conterminous downstream OMS section.
The luminous power of equipment to an OMS section with power detection can be adopted to detect in real time or periodically detect, if the luminous power deterioration of an OMS section, that is, luminous power exceedes certain thresholding, then can regulate the luminous power of an OMS section.Wherein, in the embodiment of the present invention, the luminous power of indication can comprise: light puts input power and/or single wave power.That is, input power can be put to the light of an OMS section to regulate, make it to reach light and put nominal input power, can also regulate single wave power of an OMS section, make it single popin smooth.
Owing to may impact downstream the 2nd OMS section of an OMS section the adjustment of an OMS section luminous power, therefore, in the embodiment of the present invention, after forward adjustment is carried out to the luminous power of an OMS section, oppositely can regulate the luminous power of the 2nd OMS section.Be understandable that, so-called forward regulates and oppositely regulates, and refers to and regulates in the opposite direction luminous power, such as: it is the decay controlling luminous power that forward regulates, improve luminous power, so oppositely adjustment be then control luminous power decay to reduce luminous power, vice versa.It should be noted that, for the multiple two OMS sections adjacent with an OMS section, oppositely can regulate according to the Wavelength dispatching direction of each 2nd OMS section when oppositely regulating.
In order to farthest offset the optical power adjustment of an OMS section to the impact of downstream the 2nd OMS section, optionally, the luminous power amplitude of the OMS section that forward regulates, can be identical with the luminous power amplitude of the 2nd OMS section oppositely regulated.Certainly, be understandable that, before oppositely regulating before the optical power adjustment to an OMS section and to the luminous power of the 2nd OMS section, first the luminous power of the 2nd OMS section can be detected, to determine the impact of the optical power adjustment of an OMS section on the 2nd OMS section luminous power, and then oppositely regulate according to the amplitude that affects of luminous power, to reach good reduction impact effect.
It should be noted that, relate in the embodiment of the present invention to OMS section optical power adjustment, existing various optical power adjustment mode can be adopted.Specifically can put input power as controlled plant using light: the conjunction ripple VOA before regulating light to put and/or single ripple VOA; Can also using flatness as controlled plant: the single ripple VOA regulating corresponding wavelength.Existing various optical power adjustment instrument can be adopted to regulate, and these adjustment means can manually arrange pad value and issue adjusting command, thus regulating optical power.Or, automatically can also be identified the luminous power of an OMS section and the 2nd OMS section by instrument, pad value is arranged, thus regulating optical power.
The optical signal power control method that the embodiment of the present invention provides, forward adjustment is carried out by the luminous power of the upstream OMS section to optical-fiber network, the luminous power of downstream OMS section is oppositely regulated, carry out the adjustment of luminous power to the impact of the luminous power of downstream OMS section to reduce upstream OMS section, reduce the error rate of receiving terminal OTU.
Fig. 3 is the flow chart of another embodiment of optical signal power control method provided by the invention, as Fig. 3, present embodiments provide a specific embodiment of optical signal power control method, in this embodiment, step-length can be adopted to regulate method to the optical power adjustment of each OMS section, that is, at every turn can to the amplitude of an Attenuation adjustable step-length of an OMS section, such as: can 0.5dB be regulated.
The method specifically comprises:
S201, the decay of the luminous power of an OMS section to be regulated, to reduce the decay of the luminous power of an OMS section, improve the luminous power of an OMS section.
Concrete, can be specifically regulate to close wave attenuation to the Attenuation adjustable of the luminous power of an OMS section, that is, the decay of involutory paths regulates.
S202, the attenuation amplitude of the luminous power of an OMS section regulated according to forward, regulate the decay of the luminous power of the 2nd OMS section, to improve the decay of the luminous power of the 2nd OMS section, reduce the luminous power of the 2nd OMS section.
Regulating the decay of the luminous power of the 2nd OMS section can be specifically single wave attenuation of adjustment the 2nd OMS section, that is, regulate the decay of single ripple passage.
For Fig. 2, using OMS1 section as an OMS section, OMS2 is as the 2nd OMS section, if OMS1 section wavelength power is deteriorated, then need the decay of the luminous power regulating OMS1 section, ensure that input power that light is put reaches light and puts nominal input power, bonding wave power is smooth.Concrete, the optical power attenuation of OMS1 section can be reduced, thus improve the luminous power of OMS1 section.
Contrary, when downstream OMS2 section oppositely regulates, the pad value identical with OMS1 section adjusting range can be improved, thus reduce the luminous power of OMS2, make single wave power revert to the baseline value of setting.
S203, the luminous power baseline value of the 2nd OMS section according to setting, carry out to the luminous power of the 2nd OMS section through oppositely regulating corrections and regulate, with the difference of the luminous power and baseline value that make the 2nd OMS section after correction adjustment in setting range.
As shown in Figure 2, before Fig. 2 gives forward adjustment, single wave power value of an OMS section (OMS1), the 2nd OMS section (OMS2) and the 3rd OMS section (OMS3).S203 is optional step.After the luminous power of downstream OMS2 section is oppositely regulated, the single wave power value in the OMS2 section of downstream can be checked further, such as: spectrum analysis class veneer can be checked, such as: MCA4 (4-channelspectrumanalyzerboard), MCA8, single wave power value of OPM8 (8-channelopticalpowermonitorboard) etc., judge now single wave power value, whether deviation is there is with the single wave power value recorded before OMS1 section power adjustments, namely, can using single wave power value of recording before OMS section power adjustments each in optical-fiber network luminous power baseline value as the 2nd OMS section of setting, when deviation exceeds setting range, such as: more than 0.5dB, then can carry out correction to the luminous power of OMS2 section to regulate, repair up-regulated number of times and according to actual conditions or setting can be needed, such as: can set and repair up-regulated number of times and be no more than twice at most.Revising to regulate to ensure in downstream OMS2 section not by the impact of upstream OMS1 section further, or reduces upstream OMS1 section to the impact of downstream OMS2 section.
Fig. 4 provides the optical power change schematic diagram of each OMS section in forward adjustment and reverse adjustment process.Put input power to OMS1 section light to regulate, make it to reach light and put nominal input power, can also regulate single wave power of an OMS section, make it single popin smooth after, the each wavelength power of OMS2 section raises simultaneously, accordingly, oppositely can regulate each wavelength of OMS2 section, make it to recover setting baseline value.If a certain single wave power value of OMS2 section exceedes setting range 0.5dB with setting baseline value deviation, then correction is carried out to the luminous power of OMS2 section and regulate, make it to recover setting baseline value.
S204, the error rate of receiving terminal optical wavelength conversion element OTU to be detected.
If the S205 error rate is more than or equal to setting thresholding, then before the luminous power of an OMS section being returned to forward adjustment, and before the luminous power of the 2nd OMS section being returned to oppositely adjustment.
Specifically, if to regulate the forward of luminous power in S201 and S202 and reverse adjustment is adjustment for pad value respectively, then in S205 to an OMS section luminous power return to forward regulate before, specifically refer to by the pad value of an OMS section is returned to forward regulate before; Equally, before the 2nd OMS section luminous power is returned to and oppositely regulated, specifically refer to and will the pad value of the 2nd OMS section be returned to anyway to before adjustment.
Wherein, S204 can perform after S203 step, also can perform after S202 step.Can using the adjustment process of the adjustment process of S201 and S202 as a step-length, or, when comprising S203 in the method, can using the adjustment process of the adjustment process of S201-S203 as a step-length.
After the adjustment process of a step-length terminates, can detect the error rate of receiving end OTU, if the error rate is more than or equal to setting thresholding, namely be deteriorated to a certain degree, then adjustment can be suspended, before the luminous power of the one OMS section can being returned to forward adjustment, and before the luminous power of the 2nd OMS section being returned to oppositely adjustment, specifically by the adjustment process rollback of last step-length, before returning to the adjustment process of last step-length by the luminous power of an OMS section, before the luminous power of the 2nd OMS section is returned to the adjustment process of last step-length, thus ensure that the error rate can not deterioration.
After the adjustment process of a step-length terminates, if the error rate is less than setting thresholding, then can proceed the adjustment of next step-length.
The optical signal power control method that the embodiment of the present invention provides, forward adjustment is carried out by the luminous power of the upstream OMS section to optical-fiber network, the luminous power of downstream OMS section is oppositely regulated, carry out the adjustment of luminous power to the impact of the luminous power of downstream OMS section to reduce upstream OMS section, reduce the error rate of receiving terminal OTU.Further, the method can also be carried out correction to the luminous power of the OMS section after oppositely regulating and be regulated, and to ensure in downstream OMS section not by the impact of upstream OMS section further, or reduces upstream OMS section to the impact of downstream OMS section.In addition, the method can also after forward regulates and oppositely regulates, according to the error rate deterioration of receiving terminal OTU, before upstream OMS and downstream OMS being returned to forward adjustment and reverse adjustment, thus the error rate of receiving terminal OTU is returned to before forward regulates and oppositely regulate, further reduce the possibility of receiving terminal OTU deterioration, improve the performance of receiving terminal OTU.
