Fig. 4 is a schematic flowchart of a method for testing an operation status of an ONU device in an embodiment of the present invention. Application to the passive optical control device shown in fig. 1-3. The method of FIG. 4 may include:
s402, a first optical power value obtained by an optical power meter connected with the passive optical path control device is determined.
The optical power meter is used for acquiring an optical power value of a reflected optical wave of the first optical wave after the first optical wave emitted by a PON port of the OLT equipment sequentially passes through the passive optical control device and the ONU equipment. In this embodiment, the first optical wave sequentially passes through the passive optical control device and the optical module of the ONU device, and is reflected by the optical module of the ONU device. The first optical wave has a wavelength of 1310 nm.
S404, if the first optical power value is within the optical receiving range, determining that the ONU device is operating normally.
Since the counting modes of the optical power meters of different models and types are different, for example, 0 db mw in some optical power meters indicates that there is received light, and 0 db mw in some optical power meters indicates that there is no received light, the optical power value corresponding to the operation state of the ONU device is represented by using the representation modes of the range with received light and the range without received light, instead of using a certain value (e.g., 0 db mw).
In the embodiment of the present invention, after a first optical wave emitted from a PON port of an OLT device and obtained by an optical power meter connected to a passive optical control device sequentially passes through the passive optical control device and an ONU device, and an optical power value of a reflected optical wave of the first optical wave by the ONU device is determined, and when the optical power value is within a light receiving range, it is determined that an operation state of the ONU device is normal operation. The method and the device solve the problems of low checking efficiency and high checking cost aiming at the running state of the ONU equipment, realize that the running state of the ONU equipment is quickly tested by adopting less manpower and lower equipment cost under the condition of reducing user perception, greatly improve the checking efficiency aiming at a virtual occupation port, shorten the opening time of a new service and improve the user satisfaction.
In one embodiment, after the first optical power value acquired by the optical power meter connected to the passive optical control device is determined, if the first optical power value is within the non-light-reception range, the second optical power value acquired by the optical power meter connected to the passive optical control device is determined. The optical power meter is used for acquiring the optical power value of the second optical wave reflected by the ONU equipment to the second optical wave after the second optical wave emitted by the laser light source sequentially passes through the passive optical path control device and the ONU equipment.
And if the second optical power value is in the range of no light reception, determining that the operation state of the ONU equipment is a power-off state. And if the second optical power value is a fixed value in the range of receiving light, determining that the ONU equipment does not exist.
Wherein the wavelength of the second optical wave is 1550 nanometers. Generally, the fixed value is-26 db mw to-27 db mw, and if the emission power of the laser source is-5 db mw, the emission power is-26 db mw obtained by the optical power meter after power loss after reflection by the cross section of the optical fiber.
In this embodiment, after determining that the first optical power value is within the unreceived optical range, the second optical power value acquired by the optical power meter connected to the passive optical control device is further determined, so that it can be determined that the operation state of the ONU device is a power-off state or the ONU device does not exist, and accuracy of the test result is improved.
In one embodiment, before determining the first optical power value acquired by the optical power meter connected to the passive optical control device, it may be determined whether the second optical power value acquired by the optical power meter is in the unreceived optical range when the ONU device is connected to the passive optical control device.
And if the second optical power value acquired by the optical power meter is in the range of no light reception, the adjustable optical attenuator is not adjusted. At this time, the second optical wave emitted by the laser light source is just completely received by the receiving unit device in the optical module of the ONU device, and no additional optical wave is reflected to the optical power meter.
And if the second optical power value acquired by the optical power meter is in the light receiving range, determining rotation information of an adjustable knob of the adjustable optical attenuator according to the difference between the second optical power value and the light receiving-free range, and adjusting the adjustable optical attenuator according to the rotation information so as to enable the second optical power value to be in the light receiving-free range. Wherein the rotation information includes a rotation direction and a rotation angle.
In this embodiment, before the ONU device is tested in the operating state, the adjustable optical attenuator is adjusted, so that the second optical wave emitted by the laser light source is completely received by the receiving unit device in the optical module of the ONU device, and no additional optical wave is reflected to the optical power meter, that is, the second optical power value obtained by the optical power meter is in the range of no received light, which avoids the influence on the test result caused by the excessive power of the optical wave emitted by the laser light source, and is beneficial to improving the accuracy of the test result.

The method can be applied to a scene of testing the running state of the ONU equipment connected with the port of the optical fiber distribution box or the fiber distribution box by using the passive optical path control device shown in FIGS. 1-3. The method of fig. 5 may include:

Wherein the rotation information includes a rotation direction and a rotation angle.
