Embodiment
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The Fig. 1 of take below describes a kind of Wavelength allocation method that the embodiment of the present invention one provides in detail as example, the flow chart of a kind of Wavelength allocation method that Fig. 1 provides for the embodiment of the present invention one.The executive agent of this Wavelength allocation method is OLT.As shown in Figure 1, this Wavelength allocation method comprises the following steps:
Step S101, receives the operating parameter values that the current ONU reaching the standard grade sends, N the operating parameter values in wavelength tuning district when this operating parameter values adopts N wavelength available for this ONU, and this N operating parameter values and N wavelength available are corresponding one by one.
Wherein, N > 0.The present embodiment be take N the working temperature in operating parameter values wavelength tuning district when ONU adopts N wavelength available and is described as example.
The N of the current ONU a reaching the standard grade wavelength available is identical with N the wavelength available of online ONU.When online ONU adopts N wavelength available, N the working temperature in wavelength tuning district is stored in OLT.
This wavelength available is emission wavelength or receives wavelength.
When wavelength available is the emission wavelength of ONU up channel, optical module in ONU presets the working temperature in wavelength tuning district when adopting each emission wavelength, and when ONU adopts each emission wavelength by up channel, the working temperature in wavelength tuning district is sent to OLT.
When wavelength available is the reception wavelength of ONU down channel, first ONU will receive length scanning in preset range, the wavelength scanning and can therefrom parse correct downlink data is defined as to the wavelength available of down channel, then by adopt definite down channel wavelength available time wavelength tuning district working temperature be sent to OLT.
Step S102 is that the current ONU reaching the standard grade distributes wavelength according to the operating parameter values receiving.
Concrete, the operating parameter values of the operating parameter values of the current ONU reaching the standard grade and online ONU is sorted according to order from small to large.If the operating parameter values of the ONU reaching the standard grade current is positioned at the front 1/N of sequencing queue, corresponding wavelength during the operating parameter values maximum of distributing the current ONU wavelength tuning district reaching the standard grade in N wavelength available for the current ONU that reaches the standard grade; The operating parameter values of the ONU reaching the standard grade if current at the 1/N of sequencing queue between 2/N, the operating parameter values of distributing the current ONU wavelength tuning district reaching the standard grade in N wavelength available for the current ONU reaching the standard grade corresponding wavelength time greatly time; By that analogy, the operating parameter values of the ONU reaching the standard grade if current is positioned at the last 1/N of sequencing queue, and the operating parameter values of distributing the current ONU wavelength tuning district reaching the standard grade in N wavelength available for the current ONU that reaches the standard grade is the wavelength of hour correspondence.
In a concrete example, when the working temperature for receiving is carried out Wavelength Assignment, suppose that existing M-1 ONU is online, the emission wavelength of the up channel of all ONU all can be operated in 4 wavelength X 1, λ 2, λ 3, λ 4, suppose that all ONU adopt based on temperature controlled distributed feed-back (Distributed Feed Back, DFB) laser is as transmitter, by controlling the working temperature of Distributed Feedback Laser chip, realize the tuning of 4 wavelength, the working temperature of establishing first ONU Distributed Feedback Laser chip when adopting this four wavelength is followed successively by T<sub TranNum="127">1</sub>1, T<sub TranNum="128">1</sub>2, T<sub TranNum="129">1</sub>3, T<sub TranNum="130">1</sub>when 4, the second ONU adopt this four wavelength, the working temperature of Distributed Feedback Laser chip is followed successively by T<sub TranNum="131">2</sub>1, T<sub TranNum="132">2</sub>2, T<sub TranNum="133">2</sub>3, T<sub TranNum="134">2</sub>4, the like, when M-1 ONU adopts this four wavelength, the working temperature of Distributed Feedback Laser chip is followed successively by T<sub TranNum="135">m-1</sub>1, T<sub TranNum="136">m-1</sub>2, T<sub TranNum="137">m-1</sub>3, T<sub TranNum="138">m-1</sub>4.According to the attribute of wavelength itself, while adopting this four wavelength for all ONU, the working temperature magnitude relationship of Distributed Feedback Laser chip is all λ 1 < λ 2 < λ 3 < λ 4.When M ONU will register while reaching the standard grade, when it sends to this four wavelength of employing of OLT, the working temperature of Distributed Feedback Laser chip is followed successively by T<sub TranNum="139">m</sub>1, T<sub TranNum="140">m</sub>2, T<sub TranNum="141">m</sub>3, T<sub TranNum="142">m</sub>4.For the purpose of simple, the work temperature of Distributed Feedback Laser chip in the time of can only adopting λ 4 to ONU<sub TranNum="143">1</sub>4, T<sub TranNum="144">2</sub>4 ... T<sub TranNum="145">m</sub>4 sort according to order from small to large.If T<sub TranNum="146">m</sub>4 front 1/4 in sequencing queue, when M ONU adopts λ 4, the working temperature of Distributed Feedback Laser chip, in 1/4 minimum set, be the working temperature of this M ONU distribution Distributed Feedback Laser chip corresponding wavelength X 4 when the highest; If T<sub TranNum="147">m</sub>4 in 1/4 to 2/4 of queue, and when M ONU adopts λ 4, the working temperature of Distributed Feedback Laser chip, in inferior 1/4 low set, be the inferior wavelength X 3 corresponding when high of the working temperature of this M ONU distribution Distributed Feedback Laser chip; If T<sub TranNum="148">m</sub>4 in 2/4 to 3/4 of queue, and when M ONU adopts λ 4, the working temperature of Distributed Feedback Laser chip, in inferior 1/4 high set, be the inferior wavelength X 2 corresponding when low of the working temperature of this M ONU distribution Distributed Feedback Laser chip; If T<sub TranNum="149">m</sub>4 last 1/4 in queue, when M ONU adopts λ 4, the working temperature of Distributed Feedback Laser chip, in 1/4 the highest set, be the working temperature of this M ONU distribution Distributed Feedback Laser chip corresponding wavelength X 1 when minimum.
It should be noted that, the working temperature of Distributed Feedback Laser chip sorts when ONU is adopted to λ 4, also in the time of can adopting other wavelength in four wavelength to ONU, the working temperature of Distributed Feedback Laser chip sorts, can also sort to the mean value of the corresponding working temperature of four of ONU wavelength availables, or carry out integrated ordered to the corresponding working temperature of four wavelength availables.
In addition, for the reception wavelength of down channel, also can adopt to use the same method and distribute, at this, no longer be described in detail.
Step S103, sends indication information to the current ONU reaching the standard grade, and this indication information comprises the wavelength of distributing to the current ONU reaching the standard grade.
OLT is that the current ONU reaching the standard grade distributes after corresponding wavelength, sends the indication information of the wavelength that comprises distribution to this ONU, so that this ONU determines working channel according to the wavelength receiving.
