Example 4
Referring to fig. 4 to 9, a fourth embodiment of the present invention provides an intelligent analysis method, and the present invention implements fast checking and statistics on optical fiber network resource information, can effectively detect whether optical fiber wiring routing information is matched between different racks and different machine rooms, and can transmit the collected information to constructors in electronic resources or visual dot patterns. And the staff processes the line condition between the optical fibers according to the received information. By utilizing the system, whether the interfaces of the optical transmitter and the optical receiver are connected or not can be judged efficiently, and the routing address information of the optical fiber route to be checked is returned, so that the problem that excessive resources need to be checked is solved, and the processing efficiency is greatly improved.
The slave fiber searching module part of the invention provides an optical receiver which is composed of a negative feedback signal amplification sub-module taking an operational amplifier as a core, a clock recovery sub-module and a data recovery sub-module, and can effectively improve the dynamic range and accuracy of optical fiber wiring route checking.
And a signal amplifying circuit based on an operational amplifier LM358, as shown in the figure. LM358 is a general operational amplifier with wide power supply voltage range of 3V to 36V. Because the LM358 chip has different amplification performances under different power supply voltages, and different feedback resistance values in the circuit can change the signal amplification factor, the power supply voltage of the LM358 chip and the resistance value of the feedback resistance need to be noticed when designing the signal amplification circuit, if the amplification factor is too large, the data signal voltage can exceed the identification range of the GPIO port, so that the STM32 cannot normally receive the data signal, and if the amplification factor is too small, the dynamic range of the system is reduced.
The design changes the signal amplification factor by adjusting the power supply voltage of the LM358 and the resistance value of the feedback resistor in the signal amplification circuit, so that the optimal signal amplification factor suitable for the system is found, and the dynamic range of optical fiber wiring route investigation is improved.
A test system with the addition of clock recovery and data recovery sub-modules is shown in figure 5. The clock recovery module generates a periodic clock signal by detecting a jump edge of the data of the receiving end, and compensates time delay between an original signal of a reference port and a signal received by the receiving port by using the newly generated periodic clock signal; a signal decision circuit is arranged in the data recovery module to carry out threshold decision on the data signal so as to realize identification and regeneration.
The system light emission end outputs an optical signal carrying 'information' to enter the optical fiber, the attenuation coefficient of the optical fiber is 0.2dB/km, and the dispersion coefficient is 20ps/nm/km; in the optical receiver, a photodetector semiconductor Photodiode (PIN) converts an optical signal into an electrical signal, the electrical signal is passed through a Low Pass Bessel Filter (Low Pass Bessel Filter) to reduce system noise, and then is passed through a Clock Recovery (CR) module and a Data Recovery (DR) module, an output signal is connected to a bit error rate Analyzer (BER Analyzer), and the bit error rate of the signal is detected and analyzed.
In order to test the dynamic range of the optical fiber distribution routing of the system, the experimental test of the optical attenuator simulation system under long-distance optical fiber transmission can be utilized. Firstly, the attenuation of the optical attenuator is adjusted and measured, and then the optical attenuator is connected in series into a system for experimental test. The attenuation of the optical attenuator is adjusted to simulate the loss of the optical fiber in a long distance in practice and is calculated at 0.2 dB/km.

The power supply voltage of the LM358 and the resistance value of a feedback resistor in the signal amplification circuit are respectively adjusted, and the 3.3V power supply voltage and the 5V power supply voltage are respectively used for carrying out experimental tests because the voltage of the current universal power supply is 3.3V and 5V and the power supply of the circuit of the whole system is convenient to unify; the resistance value of the feedback resistor is changed to make the amplification times of the signal amplification circuit be 2 times, 3 times and 4 times for experimental tests, and the experimental results are shown in the table.
Dynamic range of system-added signal amplification circuit investigation
The above table shows that the dynamic range of the system for checking after adding the signal amplification circuit is obviously improved, the maximum dynamic range of the LM358 is 9.24dB when the power supply is 3.3V and the signal amplification factor is 2 times, namely, the actual distance of the optical fiber to be checked is at least 46km, and the optical fiber checking work in the traditional communication machine room and the data center can be met. In the above table, the reason why the higher amplification factor is used without increasing the dynamic range is that the amplification circuit has a certain amplification performance, the signal amplification capability is limited, and the amplified signal voltage does not exceed the supply voltage of the amplification circuit.
The performance of the system is evaluated according to the error rates under different transmission rates and transmission distances under the conditions that the system does not have a CR module and a DR module, only comprises the CR module and only comprises the DR module, and comprises the CR module and the DR module. As shown in FIGS. 7 to 9, the minimum bit error rate (Min. Log of BER) of 10Kbit/s, 1Mbit/s, 100Mbit/s, and 10Gbit/s transmission rates at different transmission distances are shown,
as can be seen from fig. 7 to fig. 9, the transmission distance of the system with different transmission rates is increased by about 1.5 times by including the CR module and the DR module, and the effect is most obvious; the transmission distance is improved by about 1.2 times by only comprising the DR module; by including only the CR module, the transmission distance is not significantly changed, which is consistent with the expected result, the CR module generates a new periodic clock signal, and the DR module performs the regeneration of the data signal. The above description shows that the optical receiver proposed by the present invention can better reduce and compensate the attenuation of the data signal of the present system, and effectively extend the transmission distance.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
