Detailed Description
The embodiment of the application provides a method and a device for calculating optical power of gateway equipment, which are used for solving the problem of higher cost in the aspect of calculating the optical power of the gateway equipment in the prior art.
In order to make the technical solution of the present application better understood by those skilled in the art, the technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, shall fall within the scope of the application.
Fig. 1 is a schematic application scenario diagram of an optical power calculation method of a gateway device according to an embodiment of the present application, where the application scenario includes FTTR a main gateway and at least one sub gateway, as shown in fig. 1. In an actual usage scenario, other devices, such as an optical attenuation device, an optical splitter, etc., may be connected between the FTTR main gateway and at least one sub gateway. After the sub-gateway accesses FTTR the primary gateway, registration is completed on FTTR the primary gateway. After the sub-gateway successfully registers, the optical power of the gateway device may be calculated in the manner shown in fig. 2. The gateway registration method is in the prior art, and is not described herein.
As shown in fig. 2, the optical power calculation method of the gateway device includes the following steps S202 to S206:
S202, acquiring first sending optical power and first receiving optical power reported by a sub-gateway to a FTTR main gateway. The first transmitting optical power is the optical power generated by the sub-gateway, and the first receiving optical power is the optical power generated by the FTTR main gateway and received by the sub-gateway.
S204, calculating FTTR the link loss between the main gateway and the sub-gateway according to the first received optical power and the second transmitted optical power. The second sending optical power is the optical power generated by FTTR main gateways.
S206, calculating FTTR the second received optical power of the main gateway according to the link loss and the first transmitted optical power.
As shown in connection with fig. 1, after the sub-gateway completes registration on the FTTR main gateway, the sub-gateway sends uplink optical power, that is, first sending optical power, to the FTTR main gateway. FTTR the main gateway sends downlink optical power, namely second sending optical power, to the sub-gateway. In the optical power transmission process between the sub-gateway and the FTTR main gateway, certain link loss exists, so that the optical power received by the sub-gateway (i.e. the first received optical power) is smaller than the second transmitted optical power transmitted by the FTTR main gateway, and the optical power received by the FTTR main gateway (i.e. the second received optical power) is smaller than the first transmitted optical power transmitted by the sub-gateway.
Optionally, before performing S202, FTTR the primary gateway sends the second transmit optical power to the sub-gateway.
By adopting the technical scheme of the embodiment of the application, the transmitting optical power and the first receiving optical power which are reported to the FTTR main gateway by the sub gateway and are generated by the sub gateway are obtained, wherein the first receiving optical power is the optical power which is received by the sub gateway and is generated by the FTTR main gateway; and calculating FTTR the link loss between the main gateway and the sub-gateway according to the first received optical power and the transmission optical power generated by the FTTR main gateway, and further calculating FTTR the received optical power of the main gateway according to the link loss and the transmission optical power generated by the sub-gateway. Therefore, the technical scheme realizes the optical power calculation process of the gateway equipment by adopting a software calculation method, and omits hardware design cost and implementation cost. In addition, because the transmitted optical power generated by the sub-gateway, the first received optical power and the transmitted optical power generated by the FTTR main gateway can be accurately obtained, compared with a hardware measurement mode, the accuracy of the mode of adopting software calculation is higher, and the method can be suitable for the condition of burst received optical power at the FTTR main gateway side.
In one embodiment, when calculating FTTR the link loss between the main gateway and the sub-gateway according to the first received optical power and the second transmitted optical power, the link loss between the main gateway and the sub-gateway may be obtained FTTR by calculating the difference between the second transmitted optical power and the first received optical power. The calculation can be expressed as the following formula:
Second transmit optical power-first receive optical power = link loss
In one embodiment, when calculating FTTR the second received optical power of the primary gateway according to the link loss and the first transmitted optical power, the difference between the first transmitted optical power and the link loss may be calculated, so as to obtain the second received optical power. The calculation can be expressed as the following formula:
First transmit optical power-link loss = second receive optical power
In the above embodiment, the link loss between the FTTR main gateway and the sub-gateway is obtained by calculating the difference between the second transmitted optical power and the first received optical power, and then the received optical power of the FTTR main gateway is obtained by calculating the difference between the first transmitted optical power and the link loss, so that the optical power calculation process of the gateway device is realized by adopting the software calculation method, and the hardware design cost and the realization cost are saved. In addition, the first sending optical power, the first receiving optical power and the second sending optical power can be accurately obtained, and the difference value calculating mode is very simple, convenient and quick, so that the calculating efficiency and the accuracy of the receiving optical power of the FTTR main gateway are ensured.
Fig. 3 is a schematic flow chart of an optical power calculation method of a gateway device according to another embodiment of the present application. As shown in fig. 3, the Optical power calculation method of the gateway device is applied to the scenario shown in fig. 1, in this embodiment, FTTR the main gateway is a MINI-OLT (Optical LINE TERMINAL ), and the sub-gateway is an ONU (Optical Network Unit, optical node), which specifically includes the following steps S301-S305:
S301, the sub-gateway ONU completes registration on the main gateway MINI-OLT, and the main gateway MINI-OLT sends second sending optical power to the sub-gateway ONU.
S302, the sub-gateway ONU generates and transmits first transmission optical power and receives second transmission optical power transmitted by the main gateway MINI-OLT.
The sub-gateway ONU is internally provided with an optical module circuit system, and uplink optical power, namely first transmitting optical power, is generated by utilizing the optical module circuit system and is transmitted to the main gateway MINI-OLT.
And S303, the sub-gateway ONU reports the transmitted first transmitting optical power and the received first receiving optical power to the main gateway MINI-OLT.
The first received optical power is the optical power generated by the primary gateway MINI-OLT and received by the sub-gateway ONU, that is, when the sub-gateway ONU receives the second transmitted optical power sent by the primary gateway MINI-OLT, the first received optical power actually received is smaller than the second transmitted optical power due to the link loss.
S304, the main gateway MINI-OLT calculates the link loss between the sub-gateway ONU and the main gateway MINI-OLT according to the received first transmitting optical power and the first receiving optical power.
The link loss calculation mode is as follows: second transmit optical power-first receive optical power = link loss.
S305, the main gateway MINI-OLT calculates the optical power actually received by the main gateway MINI-OLT according to the link loss and the first transmission optical power.
The optical power actually received by the primary gateway MINI-OLT may be marked as a second received optical power, where the second received optical power is calculated in the following manner: first transmit optical power-link loss = second receive optical power.
It should be noted that the embodiment shown in fig. 3 only illustrates the case of transmitting optical power between one sub-gateway ONU and the main gateway MINI-OLT. In practical application, a plurality of sub-gateway ONUs can be connected and registered on the same main gateway MINI-OLT, in this case, when the sub-gateway ONU reports the first transmitted optical power and the received first received optical power, the unique identification information of the sub-gateway ONU itself needs to be carried, so that the main gateway MINI-OLT can determine which sub-gateway ONU reports the optical power according to the unique identification information.
Therefore, by adopting the technical scheme of the embodiment of the application, the transmitting optical power and the first receiving optical power generated by the sub-gateway are reported to the main gateway through the sub-gateway, wherein the first receiving optical power is the optical power generated by the main gateway and received by the sub-gateway, so that the main gateway can calculate the link loss between the main gateway and the sub-gateway according to the first receiving optical power and the transmitting optical power generated by the main gateway, and further calculate the receiving optical power of the main gateway according to the link loss and the transmitting optical power generated by the sub-gateway, thereby realizing the optical power calculation process of the main gateway by adopting a software calculation method, and saving the hardware design cost and the realization cost. In addition, because the transmitting optical power generated by the sub-gateway, the first receiving optical power and the transmitting optical power generated by the main gateway can be accurately obtained, compared with a hardware measurement mode, the accuracy of the mode of software calculation is higher, and the method can be suitable for the situation of burst receiving optical power at the side of the main gateway.
In one embodiment, after calculating FTTR the second received optical power of the primary gateway according to the link loss and the first transmitted optical power, accuracy detection may be performed on the calculation result of the second received optical power. Optionally, determining a calculation error of the second received light power, and comparing the calculation error with a preset error threshold, if the calculation error of the second received light power is smaller than or equal to the preset error threshold, determining that a calculation result of the second received light power meets a preset accurate condition, that is, the calculation accuracy reaches an expected value.
In one embodiment, the calculation error of the second received light power may be determined by the following steps A1-A3:
And step A1, after the test sub-gateway is accessed to the FTTR main gateway, calculating FTTR a first test received optical power of the main gateway, wherein the first test received optical power is the optical power received by the FTTR main gateway after the test sub-gateway transmits the test transmitted optical power.
The test sub-gateway may be any one or more sub-gateways. When the test sub-gateway is the same as the sub-gateway in the embodiment shown in fig. 2, the test transmit optical power is the first transmit optical power.
After the test sub-gateway is accessed and registered on the FTTR main gateway, the test sub-gateway transmits optical power, i.e., test transmission optical power, to the FTTR main gateway.
The first test received optical power is calculated in the steps S202-S206 in the embodiment shown in fig. 2, specifically, first, the test sub-gateway sends test transmission optical power (i.e. uplink test transmission optical power) to the FTTR main gateway, and the FTTR main gateway sends downlink test transmission optical power to the sub-gateway; secondly, reporting uplink test transmitting optical power and received third test receiving optical power to FTTR main gateway by the test sub gateway, wherein the third test receiving optical power is the optical power actually received for the downlink test transmitting optical power; then FTTR the primary gateway performs the following calculations: uplink test transmit optical power-link loss = first test receive optical power. Wherein link loss = downlink test transmit optical power-third test receive optical power.
And step A2, after the optical power detection device is connected between the FTTR main gateway and the test sub-gateway, detecting FTTR second test received optical power of the main gateway by using the optical power detection device.
The optical power detection device may be any existing optical power meter. The distance difference between the communication distance between the optical power detection device and the test sub-gateway and the communication distance between the FTTR main gateway and the test sub-gateway is smaller than or equal to a preset difference threshold. The preset difference threshold is set to avoid inaccurate measurement when the optical power detection device is too far from the FTTR main gateway, and in general, the preset difference threshold may be set to not more than 2 meters.
In an actual application scenario, if the FTTR main gateway and the test sub gateway are connected by using an optical fiber, the optical fiber inserted in the FTTR main gateway may be transferred to the optical power detection device, and the optical power detection device may be placed near the FTTR main gateway.
Alternatively, to ensure measurement accuracy, the wavelength of the optical power detection device may be preset to 1310nm, and the test sub-gateway may be set to a long light emission mode, so that the test sub-gateway transmits the test transmission optical power in the long light emission mode. In the long-lighting mode, the test sub-gateway continuously transmits the optical power.
And step A3, determining a calculation error of the second received light power according to the first test received light power and the second test received light power.
The absolute value of the difference between the first test received light power and the second test received light power is the calculation error of the second received light power.
In this embodiment, the first test received optical power of the FTTR main gateway is calculated by adopting a software manner (i.e., steps S202-S206 shown in fig. 2), and the optical power detection device connected between the FTTR main gateway and the test sub-gateway is used to detect the optical power actually received by the FTTR main gateway, i.e., the second test received optical power, so that the calculation error of the second received optical power is determined by calculating the difference between the first test received optical power and the second test received optical power, and the calculation error is also the calculation error of the first test received optical power. The calculation error of the received light power in the above light power calculation mode is basically within 2 dB.
Fig. 4 is a schematic application scenario diagram of an optical power calculation method of a gateway device according to another embodiment of the present application, as shown in fig. 4, where the application scenario includes a main gateway OLT, a plurality of sub-gateways (ONU 1, ONU2 … … ONUn, etc.), an optical splitter, and an optical attenuation. Wherein each sub-gateway is set to a long light emitting mode.
The following lists test results in several different test environments for the scenario shown in fig. 4. Wherein the preset error threshold is 2dB. And the ONU1 and/or ONU2 in the plurality of sub-gateways are used as test sub-gateways, and when the test sub-gateways report the optical power to the main gateway OLT, the unique identification information of the test sub-gateways can be carried, such as sub-gateway numbers of ONU1 or ONU 2. In different test environments, the values and connection positions of the beam splitter and the light attenuation may be different.
Fig. 5-7 are schematic test scenario diagrams of an optical power calculation method of a gateway device according to various embodiments of the present application, where an optical fiber on a main gateway OLT is switched onto an optical power meter, as shown in fig. 5-7, while the optical power meter is placed near the main gateway OLT.
In one embodiment, as shown in FIG. 5, 1 is employed: 2 beam splitters and 10dB optical attenuation is added on the main light path. In this test environment, the test results are shown in table 1 below:
TABLE 1
In one embodiment, as shown in FIG. 5, 1 is employed: 4 beam splitters and 10dB optical attenuation is added on the main light path. In this test environment, the test results are shown in table 2 below:
TABLE 2
In one embodiment, as shown in fig. 6, the splitter includes 30% power ports and 70% power ports. Adopts 1: and 5, an unequal optical splitter, wherein a 30% power port of the optical splitter is used for connecting the test sub-gateway ONU1 and the ONU2, and no optical attenuation is used. In this test environment, the test results are shown in table 3 below:
TABLE 3 Table 3
In one embodiment, as shown in fig. 7, the splitter includes 30% power ports and 70% power ports. Adopts 1:5 unequal splitters and the sub-gateway ONU1 was tested by 10dB optical attenuation connection using the 70% power port of the splitter. In this test environment, the test results are shown in table 4 below:
TABLE 4 Table 4
As can be seen from the above embodiments, the calculation errors of the optical power calculation modes provided by the technical scheme are all smaller than the preset error threshold value by 2dB, and it can be seen that the accuracy of the calculation result of the received optical power of the FTTR main gateway is higher.
