In the embodiment of the present application, step 201 can be executed before step 202 or step 201 can after step 202, It is executed before step 205.

Step 203, second device determine the first link according to the reception power and Initial Trans of the first optical signal The consume of first link.

In the embodiment of the present application, second device receive that first device is sent with Initial Trans by the first link the One optical signal.After second device receives the first optical signal, the reception power of the first optical signal can detect, and according to first The reception power and Initial Trans of optical signal determine the first link consume of the first link.Initial Trans are to be preset in Transmission power on first device and second device.

The consume of the first link, second device are subtracted since the reception power of the first optical signal is equal to Initial Trans The difference of Initial Trans and the reception power of the first optical signal can be determined as to the consume of the first link.

Step 204, second device send the second optical signal by the second chain road direction first device.

Step 204 executes after step 203.That is, after second device determines the consume of the first link, second Device sends the second optical signal by the second chain road direction first device.

Wherein, the transmission power of second optical signal is determined according to the consume of the first link and Initial Trans.Tool Body, after second device determines the consume of the first link, determine that the second light is believed according to the consume of the first link and Initial Trans Number transmission power, then by the second link with the transmission power of determining second optical signal to first device send second Optical signal.

Step 205, first device is consumed according to reception power, the second link of the second optical signal and Initial Trans are true Fixed first link consume.

In the embodiment of the present application, after first device receives the second optical signal that second device is sent by the second link, The reception power of the second optical signal is detected, and according to the reception power of the second optical signal, the consume of the second link and initial transmissions function Rate determines that the first link consumes.

Step 206, first device consume the transmission power of the first link of adjustment according to the first link.

In the embodiment of the present application, after first device determines the consume of the first link, according to the first link consume adjustment first The transmission power of link.

For example, as shown in figure 3, first device determines that the second link consumes P_TBFor 13dBm (decibel milliwatt).First dress It sets with Initial Trans P₀The first optical signal is sent to second device.After second device receives the first optical signal, the is determined The reception power of one optical signal.As it can be seen that the reception power of the first optical signal is P₀-P_TA, wherein P_TAFor the first chain of the first link Road consume.After second device determines the reception power of the first optical signal, by Initial Trans P₀With connecing for the first optical signal The difference for receiving power is determined as the first link consume P_TA.Assuming that Initial Trans P₀For 20dBm, the reception power of the first optical signal For 8dBm, then the first link consumes P_TAFor 12dBm.

Second device determines that the first link consumes P_TALater, P is consumed according to the first link_TAWith Initial Trans P₀It determines The transmission power of second optical signal, and the second optical signal is sent with determining transmission power by the second chain road direction first device. First device is according to the reception power P of the second optical signal₁, the second link consume P_TBWith Initial Trans P₀Determine the first link Consume P_TA.For example, the transmission power of the second optical signal can be Initial Trans P₀P is consumed with the first link_TAThe sum of, i.e. P₀ +P_TA.Therefore, the reception power P of the second optical signal₁=P₀+P_TA-P_TB.First device is according to the reception power P of the second optical signal₁、 Second link consumes P_TBWith Initial Trans P₀It just can determine that the first link consumes P_TA, i.e. P_TA=P₁-P₀+P_TB.Certainly, second The transmission power of optical signal may be to consume P according to the first link_TAWith Initial Trans P₀Other determining transmission powers, The embodiment of the present application is without limitation.

First device determines that the first link consumes P_TALater, so that it may which P is consumed according to the first link_TAAdjust the first link Transmission power.

As it can be seen that by implementing method described in Fig. 2, first device can determine the link consume of transmitting link, Jin Ergen According to the transmission power of link consume adjust automatically optical signal.Therefore, by implementing method described in Fig. 2, deployment light decay is not had to Subtract device can the transmission power automatically to the optical signal of first device be adjusted.

In a kind of possible embodiment, Initial Trans are greater than the receiving sensitivity of second device, and less than the The maximal received power of two devices.The transmission power of first link adjusted is that Initial Trans and the first link consume it With.Wherein, the receiving sensitivity of second device refers to that second device can be properly received the minimum reception power of signal.The The maximal received power of two devices is the maximal received power that second device can receive signal.

By implementing the possible embodiment, the reception power that second device receives the optical signal is initial transmissions function Rate.Since Initial Trans are greater than the receiving sensitivity of second device, and it is less than the maximal received power of second device, because This, second device is to the reception power of optical signal in reasonable range.Therefore, by implementing the embodiment, first device can Suitable transmission power automatically is adjusted to the transmission power of the optical signal of first device, connects second device to optical signal Power is received in reasonable range.

In a kind of possible embodiment, when second device determines that the consume of the first link is less than predetermined power threshold value, The transmission power of second optical signal is to consume compensated power by the first link, and the transmission power of second optical signal is The sum of the consume of first link and Initial Trans.

Correspondingly, first device is consumed according to reception power, the second link of the second optical signal and Initial Trans are true The specific embodiment of fixed first link consume the following steps are included:

(11) first device detects the reception power of the second optical signal, and determines the first compensation power Y₁Value, Y₁=P₁+ P_TB-P₀, P₁For the reception power of the second currently detected optical signal, P_TBFor the consume of the second link, P₀For Initial Trans.

(12) when first compensates power Y₁Value be less than predetermined power threshold value when, first device by first compensate power Y₁'s Value is determined as the consume of the first link.

For example, as shown in figure 4, second device mode according to described in above-mentioned Fig. 3 determines that the first link consumes P_TA For 12dBm.First device determines that the second link consumes P_TBFor 13dBm.

If predetermined power threshold value P_THFor 14dBm, then second device determines that the first link consumes P_TALater, second device is true The transmission power of fixed second optical signal is P₀+P_TA, and the is sent by the second chain road direction first device with determining transmission power Two optical signals.After first device receives the second optical signal, the reception power P of the second optical signal is determined₁, and determine that first mends Repay power Y₁Value, Y₁=P₁+P_TB-P₀.The reception power P of second optical signal₁For 19dBm, the second link consumes P_TBFor 13dBm, Initial Trans P₀For 20dBm, therefore the first compensation power Y₁Value be 12dBm.Due to the first compensation power Y₁Value be less than Predetermined power threshold value, therefore, first device determine that the first link consumes P_TAFor 12dBm.Last first device uses the first link Consume P_TAAdjust the transmission power of the first link.Fig. 4 is P with transmission power adjusted_TA+P₀For.

By implementing the possible embodiment, the first link can be consumed the hair of compensation to the second link by second device Power is penetrated accurately to notify the first link to consume to first device.

Optionally, when second device determines that the consume of the first link is greater than or equal to predetermined power threshold value, the first link consumption Damage is divided into N+1 times and compensates to the transmission power of the second link, and the preceding compensated transmission power of n times is predetermined power threshold The sum of value and Initial Trans, the compensated transmission power of last time are P_xThe sum of with Initial Trans, wherein P_TA= N*P_TH+P_x, P_TAFor the consume of the first link, P_THFor predetermined power threshold value, N is positive integer, P_xMore than or equal to zero, and it is less than default Power threshold；The transmission power of second optical signal alternately changes according to compensated transmission power and Initial Trans.

Correspondingly, first device is consumed according to reception power, the second link of the second optical signal and Initial Trans are true The specific embodiment of fixed first link consume is further comprising the steps of in addition to including above-mentioned (11) and (12):

(13) when first compensates power Y₁Value be equal to predetermined power threshold value when, first device continues to test the second optical signal Reception power, and continue to determine the first compensation power Y according to the reception power of the second optical signal detected₁Value.

(14) when first compensates power Y₁Value be greater than zero, and be less than predetermined power threshold value when, first device stop detection The reception power of second optical signal and stopping determine the first compensation power Y₁Value, and determine P_xValue be and to be less than greater than zero First compensation power Y of predetermined power threshold value₁Value.

(15) when the reception power for detecting the second optical signal is that the first reception power continuously reaches preset duration, first Device stops the reception power of the second optical signal of detection and stops determining the first compensation power Y₁Value, and determine second device The power P of last time compensation_xIt is zero, which is the difference that Initial Trans and the second link consume.

(16) first device determines the times N of the transmission power with predetermined power threshold compensation to the second link, the times N For the first compensation power Y₁Value be equal to predetermined power threshold value total quantity, the N be positive integer.

(17) first device is according to predetermined power threshold value, the times N and P_xDetermine that the first link consumes, wherein P_TA=N* P_TH+P_x。

For example, as shown in figure 5, second device mode according to described in above-mentioned Fig. 3 determines that the first link consumes P_TA For 12dBm.First device determines that the second link consumes P_TBFor 13dBm.

If predetermined power threshold value P_THFor 5dBm, due to P_TA=N*P_TH+P_x=12dBm, N are positive integer, P_xIt is greater than or equal to Zero, and it is less than predetermined power threshold value P_TH.Therefore, N is equal to 2, P_xEqual to 2dBm.Second device determines that the first link consumes P_TAIt Afterwards, the first link is consumed into P_TADivide 3 times and the transmission power of the second link is compensated, the hair of the second link after compensating for the first time Penetrating power is P₀+ 5dBm, the transmission power of the second link is P after second of compensation₀+ 5dBm, the second link after third time compensates Transmission power is P₀+2dBm.Second device is according to compensated transmission power and Initial Trans P₀Alternately variation sends second Optical signal.For example, the transmission power variation of the second optical signal can be as shown in Figure 6.

Correspondingly, first device can detect the reception power of the second optical signal.First device detects the second light for the first time The reception power P of signal₁For P₀+5-P_TB.First device is according to the reception power P of the second currently detected optical signal₁Determine One compensation power Y₁Value.Due to the first compensation power Y₁=P₁+P_TB-P₀=5dBm, the first compensation power Y₁Value be equal to it is default Power threshold P_TH, therefore first device continues to test the reception power of the second optical signal, and continues according to the second light detected The reception power of signal determines the first compensation power Y₁Value, and first device record predetermined power threshold value compensated to second The number of the transmission power of link is 1.Optionally, first device can start counter and be compensated predetermined power threshold value to second The number of the transmission power of link is counted.The reception power P for the second optical signal that first device detects for the second time₁For P₀- P_TB, first device is according to the reception power P of the second optical signal detected for the second time₁Determine the first compensation power Y₁=P₁+P_TB- P₀=0dBm.The reception power P for the second optical signal that first device third time detects₁For P₀+5-P_TB, first device is according to The reception power P of the second optical signal detected three times₁Determine the first compensation power Y₁=P₁+P_TB-P₀=5dBm.Therefore first It is 2 that device, which records predetermined power threshold value by the number compensated to the transmission power of the second link, i.e. counter adds 1.First device The reception power of 4th the second optical signal detected is P₀-P_TB, first device believes according to the second light detected for the 4th time Number reception power P₁Determine the first compensation power Y₁=P₁+P_TB-P₀=0dBm.The 5th the second light detected of first device The reception power P of signal₁For P₀+2-P_TB, due to the reception power P of the second optical signal detected according to the 5th time₁Determining One compensation power Y₁=P₁+P_TB-P₀=2dBm, the first compensation power Y₁Value be less than predetermined power threshold value P_TH(i.e. 5), and be greater than 0, then first device determines P_xFor 2dBm.When first device detects the first compensation power Y₁Value be less than predetermined power threshold value P_TH (i.e. 5dBm), and be greater than 0 when, first device stop detection the second optical signal reception power and stop determine first compensation function Rate Y₁Value.Finally, it is 2 that first device, which determines that predetermined power threshold value is compensated to the times N of the transmission power of the second link, and And P_xFor 2dBm.First device determines that the first link consumes P_TA=N*P_TH+P_x.Last first device consumes P using the first link_TA Adjust the transmission power of the first link.Fig. 5 is P with transmission power adjusted_TA+P₀For.

Again for example, if predetermined power threshold value P_THFor 6dBm, due to P_TA=N*P_TH+P_x=12dBm, N are positive integer, P_x More than or equal to zero, and it is less than predetermined power threshold value P_TH.Therefore, N is equal to 2, P_xEqual to 0dBm.Second device determines the first link Consume P_TALater, the first link is consumed into P_TAThe transmission power of second link is compensated, the after compensating for the first time points for 3 times The transmission power of two links is P₀+ 6, the transmission power of the second link is P after second of compensation₀+ 6, the second chain after third time compensates The transmission power on road is P₀+0.Second device is according to compensated transmission power and Initial Trans P₀Alternately variation sends the Two optical signals.For example, the variation of the second optical signal can be as shown in Figure 7.

Correspondingly, first device can detect the reception power of the second optical signal.First device detects the second light for the first time The reception power P of signal₁For P₀+6-P_TB.First device is according to the reception power P of the second optical signal detected for the first time₁It determines First compensation power Y₁Value.Due to the first compensation power Y₁=P₁+P_TB-P₀=6dBm, the first compensation power Y₁Value be equal to it is pre- If power threshold P_TH, therefore first device continues to test the reception power of the second optical signal, and continues according to second detected The reception power of optical signal determines the first compensation power Y₁Value, and first device record predetermined power threshold value is compensated to the The number of the transmission power of two links is 1.The reception power P for the second optical signal that first device detects for the second time₁For P₀- P_TB, first device is according to the reception power P of the second optical signal detected for the second time₁Determine the first compensation power Y₁=P₁+P_TB- P₀=0dBm.The reception power P for the second optical signal that first device third time detects₁For P₀+6-P_TB, first device is according to The reception power P of the second optical signal detected three times₁Determine the first compensation power Y₁=P₁+P_TB-P₀=6dBm.Therefore first It is 2 that device, which records predetermined power threshold value by the number compensated to the transmission power of the second link, i.e. counter adds 1.First device The reception power P of 4th the second optical signal detected₁For P₀-P_TB, and continuous 2ms detects the reception of the second optical signal Power P₁For P₀-P_TB, therefore, first device determines P_xFor 0dBm.When first device detects that continuous 2ms reception detects second The reception power of optical signal is P₀-P_TBWhen, first device stops the reception power of the second optical signal of detection and stops determining the One compensation power Y₁。

Finally, first device determines that N is 2, and P_xFor 0dBm.First device determines that the first link consumes P_TA=N*P_TH+ P_x。

(21) when first compensates power Y₁Value be equal to predetermined power threshold value when, first device continues to test the second optical signal Reception power, and continue to determine the first compensation power Y according to the reception power of the second optical signal detected₁Value.

(22) during first device detects the reception power of the second optical signal, target power P is determined₃, the target Power P₃=n*P_TH+P₀, n is fixed first compensation power Y₁Value be equal to predetermined power threshold value quantity.

(23) as target power P₃Greater than first device maximum transmission power when, stop detection the second optical signal reception Power and stopping determine the first compensation power Y₁Value, and to host reporting fault information.Wherein, which can be first Equipment where device, the first equipment where the first device as described in above-mentioned communication system.

For example, if second device determines that the first link consumes P_TAFor 30dBm, predetermined power threshold value P_THFor 4dBm, then Second device, which is divided 8 times, compensates the transmission power of the second link, and the power of preceding 7 compensation are predetermined power threshold value P_TH(i.e. 4), the power of last time compensation is P_x(i.e. 2dBm).If the maximum transmission power of first device is 55dBm, initial transmissions function Rate P₀For 40dBm, then the first compensation power Y is determined in first device₁Value be equal to predetermined power threshold value quantity be 4 when, target Power P₃=4*P_TH+P₀=56dBm.Due to target power P at this time₃Greater than the maximum transmission power of first device, then first device Stop the reception power of the second optical signal of detection and stops determining the first compensation power Y₁Value, and to host reporting fault believe Breath.

Optionally, when first device determines target power P₃Greater than first device maximum transmission power when, and second Link consumes P_TBLess than predetermined power threshold value P_THWhen, first device can also be to second device with transmission power P₀+P_TBAnd P₀+P_TH Optical signal is sent, alternately to notify second device to stop sending the second optical signal.Second device detects the light letter of the first link Number reception power be P₀+P_TB-P_TAAnd P₀+P_TH-P_TAWhen alternately changing, stop sending the second optical signal.

When first device determines that target power P3 is greater than the maximum transmission power of first device, illustrate that the first link consumes P_TAIt is excessive, it has not needed to consume P using the first link at this time_TAAdjust the transmission power of the first link, therefore first device is not Need to continue to test the reception power of the second optical signal to determine that the first link consumes P_TA.As it can be seen that by implementing the optional side Formula, first device can notify second device to stop sending the second optical signal in time, be conducive to the CPU money for saving second device Source.

Optionally, first device continues to send optical signal to second device during receiving the second optical signal.If the Two devices do not receive any optical signal by the first link within a preset period of time during sending the second optical signal, then Second device is reported to host is used to indicate the instruction information that the corresponding optical fiber of the first link is pulled out.
