Specific embodiment
The present invention is described further with reference to the accompanying drawing.
Optical fiber monitoring method of the invention carried out on the looped network that an interchanger and optical fiber form data acquisition and
It calculates, as shown in Figure 1, including the sub-network for the looped network that interchanger N, interchanger R and interchanger L are formed, tests optical fiber
Situation, it is only necessary to acquire the optical power data of the interchanger at the optical fiber both ends.The present embodiment is to test 1 section of optical fiber and both ends
Illustrate for interchanger R and interchanger L.
A kind of industrial ethernet switch optical fiber monitoring method, specifically includes following procedure:
One looped network is formed using interchanger N, interchanger R and interchanger L, the friendship at 1 both ends of optical fiber is tested by computer acquisition
Change planes R and interchanger L received optical power and transmitting optical power.It can be acquired by the network interface connection of computer and interchanger
Optical power；Because the optical fiber used is one fine two-way, interchanger R and interchanger L have transmitting optical power and receive light function
Rate.
The fibre loss of optical fiber is calculated according to received optical power and transmitting optical power.Interchanger R is to the direction interchanger L
Transmission obtains the fibre loss of the direction using the received optical power that the transmitting optical power of interchanger R subtracts interchanger L；Exchange
Transmission of the machine L to the direction interchanger R is somebody's turn to do using the received optical power that the transmitting optical power of interchanger L subtracts interchanger R
The fibre loss in direction.
Output optical fibre loss, the relation curve for emitting optical power and time, analyze fibre loss state.Because being
Light data is acquired using computer, light data can be saved in real time, can be formed continuously convenient for analysis
Related data figure.It is specific: (1) to make the relation line of fibre loss RL and fibre loss LR and time in two-dimensional coordinate A；And
The early warning value and alarming value of fibre loss are set in two-dimensional coordinate A；(2) make interchanger R and interchanger L in two-dimensional coordinate B
Transmitting optical power and the relation line of time, and in two-dimensional coordinate B setting transmitting optical power early warning value and alarming value；(3)
According to the fault condition of two-dimensional coordinate A and two-dimensional coordinate B analysis optical fiber.
The analytic process of on-line monitoring:
A. as shown in Figures 2 and 3, if the transmitting optical power of interchanger R and interchanger L is essentially unchanged, but fibre loss RL
Increase suddenly with fibre loss LR, and be more than alarming value, judges that optical fiber damage or current shape need to be improved (such as optical fiber
Appearance disk line is too long, or by excessive tortuous situation).Since injury region, too long fiber cable and excessive complications can all be made
At the loss of optical power, the case where telling user's optical fiber to use.When loss reaches the early warning value of setting, optical fiber can also work,
But may remind the user that and carry out inspection improvement, it avoids that the case where optical fiber uses must be cut off, causes economic loss；If loss
Reach the alarming value of setting, indicates that fibre loss is serious, need to carry out emergent management.
B. as shown in Figure 4 and Figure 5, if the transmitting optical power for the R and interchanger L that changes planes is essentially unchanged, but fibre loss
RL and fibre loss LR increases to limiting value suddenly, and both ends received optical power is 0, then determines that optical fiber has disconnected.Because only that
Optical fiber, which is fully disconnected, can be only achieved the wireless big of loss, and receiving end does not receive light, and user must make the optical fiber of disconnection at this time
Respective handling.
C. as shown in Figure 6 and Figure 7, or if fibre loss RL and fibre loss LR without significant change, but are handed over
Significant change occurs for one of the transmitting optical power of R or interchanger L of changing planes, then determines that the optical module for emitting optical power change goes out
Existing failure.During sending and receiving for light, fibre loss is commonly taken place on optical fiber, if fibre loss is constant,
But the problem of emitting optical power change, at this moment can effectively excluding optical fiber, effectively judgement is that optical module goes wrong,
User should carry out inspection processing to corresponding optical module.Secondly, if only one of them hair of fibre loss RL and fibre loss LR
Raw significant change, but the transmitting optical power of interchanger R and interchanger L then determines the optical fiber damage of variation all without significant change
Corresponding transmitting terminal optical module is consumed to break down；Two-way optical fiber fine for one is then bound to make two-way if it is fiber failure
Propagation has fibre loss variation, if only one of which direction has apparent light loss to change, can effectively exclude light
Fine problem finds the problem of corresponding to optical module.
The invention is not limited to specific embodiments above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.If this
Field technical staff is altered or modified not departing from the unsubstantiality that spirit of the invention is done, should belong to power of the present invention
The claimed range of benefit.
