Description

Technical Field

[0001] The present invention relates to the technical field of laser measuring instruments, and in particular to a high-bandwidth CAT6-fiber composite communication cable system. Background Art

[0002] In existing technologies, communication cable systems have become key infrastructure supporting emerging fields such as 5G, AI, and the Industrial Internet. The length limit of CAT6A network cable channels is 100m. This distance is mainly suitable for high-speed cabling in large enterprises, with a transmission speed of up to 10Gbps. The 10Gbps transmission speed strictly requires the CAT6A network cable cabling performance to be as high as a test frequency of 500MHz. Single-mode optical fiber is suitable for long-distance, high-speed data transmission, and can achieve transmission distances of tens of kilometers or even longer; multi-mode optical fiber is more suitable for short-distance transmission, such as network connections within buildings or campuses. It has relatively low costs and can support higher data rates. As the core carrier of modern information infrastructure, the technological evolution of communication cable systems has always revolved around three main lines: bandwidth improvement, extended transmission distance, and enhanced anti-interference capabilities.

[0003] Chinese Patent Publication No. CN114270162A discloses a fiber optic cable sensing device, a fiber optic cable sensing method, and a program. The purpose of the invention is to provide a fiber optic cable sensing device that can measure the longitudinal distribution of curvature and torsion without using a fiber optic sensor with a special structure. The device includes: a unit that inputs data on the longitudinal distribution of strain (bending loss, polarization fluctuation) measured for each optical fiber contained in the measured fiber optic cable and data representing the position of each optical fiber as a measurement object on the cable cross section; a unit that calculates the curvature vector κ of the measured fiber optic cable at the same location based on the strain (bending loss, polarization fluctuation) of each optical fiber and the position of the optical fiber on the cable cross section; and a unit that calculates the torsion rate τ of the measured fiber optic cable at the location based on the calculated curvature vector κ.

[0004] It can be seen that the existing technology has the following problems: since the actual position of each optical fiber on the cross section may deviate from the nominal position, the input optical fiber position data is inaccurate; the physical contact between the optical fiber and the copper cable or other reinforcing components may introduce additional strain, interfering with the measurement of bending loss and polarization fluctuation, resulting in insufficient test stability of the composite communication cable. Summary of the Invention

[0005] To this end, the present invention provides a high-bandwidth CAT6-fiber composite communication cable system to overcome the problems in the prior art, such as the deviation between the actual position of each optical fiber on the cross section and the nominal position, resulting in inaccurate input optical fiber position data, and the physical contact between the optical fiber and the copper cable or other reinforcing members may introduce additional strain, interfering with the measurement of bending loss and polarization fluctuation, resulting in insufficient test stability of the composite communication cable.

[0006] To achieve the above objectives, the present invention provides a high-bandwidth CAT6-fiber composite communication cable system, comprising:

[0007] A composite cable module, for transmitting communication signals by forming a composite communication cable through a CAT6 network cable and an optical fiber cable, comprising a network cable transmission unit for providing a CAT6 network cable channel for transmitting the electrical signal in the communication signal, and an optical fiber transmission unit connected to the network cable transmission unit for providing an optical fiber channel for transmitting the optical signal in the communication signal;

[0008] a test module connected to the composite cable module and used to perform a performance test on the composite communication cable, comprising a signal generator for providing a test signal, a filter connected to the signal generator for filtering the test signal, and a temperature sensor provided in a test area for detecting the temperature of the test area;

[0009] A control module is connected to the composite cable module and the test module, and is used to determine the bit error rate threshold of the optical fiber cable based on the average transmission delay time of the test signal, or to determine the cutoff frequency of the filter based on the absolute error rate of the transmission rate of the composite communication cable, and to determine the duty cycle of the signal generator based on the temperature rise rate of the test area.

[0010] Furthermore, the network cable transmission unit includes:

[0011] Unshielded twisted pair cables are used to transmit communication signals in the form of electrical signals;

[0012] A cross skeleton connected to the unshielded twisted pair cables to separate each pair of unshielded twisted pair cables into different spatial areas;

[0013] an insulating layer connected to the unshielded twisted pair wires to prevent current leakage;

[0014] a sheath connected to the cross frame to protect the device from external physical damage;

[0015] A ripcord is connected to the jacket for stripping the jacket during cable installation, termination, and repair.

[0016] Furthermore, the optical fiber transmission unit includes:

[0017] an optical fiber connected to the sheath for transmitting an optical signal;

[0018] A steel wire reinforcer is connected to the optical fiber to enhance the tensile strength and resist tensile stress.

[0019] Furthermore, the control module is used to determine whether the test stability of the composite communication cable meets the requirements based on the average transmission delay time of the test signal. If the average transmission delay time of the test signal is greater than a preset first delay time, it is determined that the test stability of the composite communication cable does not meet the requirements;

[0020] The control module is used to preliminarily determine that the test accuracy of the composite communication cable does not meet the requirements when the average transmission delay duration of the test signal is greater than the preset first delay duration and less than or equal to the preset second delay duration, and to determine whether the test accuracy of the composite communication cable meets the requirements based on the absolute error of the transmission rate of the composite communication cable.

[0021] Furthermore, the control module is configured to increase the bit error rate threshold of the optical fiber cable when the average transmission delay duration of the test signal is greater than the preset second delay duration;

[0022] The increase range of the bit error rate threshold of the optical fiber cable is determined by the difference between the average transmission delay time of the test signal and the preset second delay time.

[0023] Furthermore, the control module is used to determine whether the test accuracy of the composite communication cable meets the requirements based on the absolute error of the transmission rate of the composite communication cable. If the absolute error of the transmission rate of the composite communication cable is greater than a preset first error, it is determined that the test accuracy of the composite communication cable does not meet the requirements.

[0024] Furthermore, the control module is configured to increase the cutoff frequency of the filter when the absolute error of the transmission rate of the composite communication cable is greater than a preset first error and less than a preset second error.

[0025] Furthermore, the control module is used to preliminarily determine that the test environment stability of the composite communication cable does not meet the requirements when the absolute error of the transmission rate of the composite communication cable is greater than or equal to the preset second error, and determine whether the test environment stability of the composite communication cable meets the requirements based on the temperature rise rate of the test area.

[0026] Furthermore, the increase range of the cut-off frequency of the filter is determined by the difference between the absolute error of the transmission rate of the composite communication cable and a preset first error.

[0027] Furthermore, the control module is used to determine whether the test environment stability of the composite communication cable meets the requirements based on the temperature increase rate of the test area; if the temperature increase rate of the test area is greater than a preset increase rate, it is determined that the test environment stability of the composite communication cable does not meet the requirements, and the duty cycle of the signal generator is reduced;

[0028] The reduction range of the duty cycle of the signal generator is determined by the difference between the temperature increase rate of the test area and the preset increase rate.

[0029] Compared with the prior art, the beneficial effect of the present invention is that the system of the present invention determines the bit error rate threshold of the optical fiber cable according to the average transmission delay time of the test signal by setting a composite cable module, a test module and a control module. Since the preparation error may occur during the installation of the connector, the insulation layer may be damaged after the connector is connected, such as cracks or breakage, which leads to a decrease in its insulation performance, thereby causing signal leakage and crosstalk. By increasing the bit error rate threshold of the optical fiber cable, the increase in the bit error rate caused by the damage to the insulation layer can be tolerated to a certain extent, avoiding the system from being too sensitive and unstable. The cutoff frequency of the filter is determined according to the absolute error of the transmission rate of the composite communication cable. Since the cable certification tester will gradually Aging causes performance changes, which in turn affects the accuracy of the equipment. By increasing the cutoff frequency of the filter, the filter can allow higher frequency signals to pass through, which helps to compensate for the high-frequency signal processing capability lost due to aging of electronic components. Signals containing high-frequency components can be acquired more accurately, thereby improving measurement accuracy. The duty cycle of the signal generator is determined according to the temperature rise rate of the test area. Since the electronic components in the test equipment consume electrical energy when working, part of the electrical energy will be converted into heat energy, causing the equipment to heat up, thereby causing the test environment temperature to rise. By reducing the duty cycle of the signal generator, the continuous working time of the equipment can be reduced without affecting the test task, thereby reducing heat accumulation and reducing the magnitude of the test environment temperature increase caused by equipment heating.

[0030] Furthermore, the system of the present invention determines the bit error rate threshold of the optical fiber cable by setting a preset first delay time and a preset second delay time. Since the insulation layer may be damaged after connection with the connector due to preparation errors when installing the connector, such as cracks or breakage, its insulation performance is reduced, thereby causing signal leakage and crosstalk. By increasing the bit error rate threshold of the optical fiber cable, the increase in the bit error rate caused by damage to the insulation layer can be tolerated to a certain extent, avoiding the system from being too sensitive and unstable, thereby improving the test stability of the composite communication cable.

[0031] Furthermore, the system of the present invention determines the cutoff frequency of the filter by setting a preset first error amount and a preset second error amount. Since the cable certification tester will gradually age after long-term use, resulting in performance changes, which in turn affects the accuracy of the equipment, by increasing the cutoff frequency of the filter, the filter can allow higher frequency signals to pass through, which helps to compensate for the high-frequency signal processing capability lost due to aging of electronic components, and can more accurately obtain signals containing high-frequency components, thereby improving measurement accuracy and further improving the test stability of composite communication cables.

[0032] Furthermore, the system of the present invention determines the duty cycle of the signal generator by setting a preset increase rate. Since the electronic components in the test equipment consume electrical energy when working, part of the electrical energy will be converted into heat energy, causing the equipment to heat up, thereby causing the test environment temperature to rise. By reducing the duty cycle of the signal generator, the continuous working time of the equipment can be reduced without affecting the test task, thereby reducing heat accumulation and reducing the amplitude of the test environment temperature increase caused by equipment heating, further improving the test stability of the composite communication cable.

A high-bandwidth CAT6-fiber composite communication cable system according to the present invention comprises:

[0043] A composite cable module, for transmitting communication signals by forming a composite communication cable through a CAT6 network cable and an optical fiber cable, comprising a network cable transmission unit for providing a CAT6 network cable channel for transmitting the electrical signal in the communication signal, and an optical fiber transmission unit connected to the network cable transmission unit for providing an optical fiber channel for transmitting the optical signal in the communication signal;

[0044] a test module connected to the composite cable module and used to perform a performance test on the composite communication cable, comprising a signal generator for providing a test signal, a filter connected to the signal generator for filtering the test signal, and a temperature sensor provided in a test area for detecting the temperature of the test area;

[0045] A control module is connected to the composite cable module and the test module, and is used to determine the bit error rate threshold of the optical fiber cable based on the average transmission delay time of the test signal, or to determine the cutoff frequency of the filter based on the absolute error rate of the transmission rate of the composite communication cable, and to determine the duty cycle of the signal generator based on the temperature rise rate of the test area.

[0046] Specifically, the CAT6 network cable is a network cable with a bandwidth of 250MHz.

[0047] Specifically, the optical fiber 7 cable is a G6572B6.a2 fiber core.

[0048] Specifically, the electrical signals in communication signals include Ethernet data signals, digital language data signals, and device control signals. Electrical signals are generally used in short-distance, low-bandwidth scenarios.

[0049] Specifically, optical signals in communication signals include Ethernet data optical signals, high-definition video optical signals, and wavelength division multiplexing optical signals. Optical signals are generally used in long-distance, high-bandwidth scenarios.

[0050] Specifically, the filter includes a low-pass filter, a high-pass filter and a band-pass filter, wherein the preferred embodiment is a low-pass filter.

[0051] Specifically, the bit error rate threshold of an optical fiber cable refers to a critical value of the bit error rate specified to ensure communication quality and normal operation of the system.

[0052] Specifically, the network cable transmission unit includes:

[0053] Unshielded twisted pair cables are used to transmit communication signals in the form of electrical signals;

[0054] A cross skeleton connected to the unshielded twisted pair cables to separate each pair of unshielded twisted pair cables into different spatial areas;

[0055] an insulating layer connected to the unshielded twisted pair wires to prevent current leakage;

[0056] a sheath connected to the cross frame to protect the device from external physical damage;

[0057] A ripcord is connected to the jacket for stripping the jacket during cable installation, termination, and repair.

[0058] Specifically, the optical fiber transmission unit includes:

[0059] an optical fiber connected to the sheath for transmitting an optical signal;

[0060] A steel wire reinforcer is connected to the optical fiber to enhance the tensile strength and resist tensile stress.

[0061] Specifically, the optical fiber 7 comprises a 0.45 mm tensile steel wire.

[0062] Specifically, the sheath 5 is a butterfly-shaped middle layer made of white low-smoke zero-halogen material.

[0063] In practice, the system of the present invention determines the bit error rate of the optical fiber 7 according to the average transmission delay time of the test signal by setting a composite cable module, a signal conversion module, a test and verification module and a control module. Since the preparation error may occur when installing the connector, the insulation layer 3 may be damaged after the connector is connected, such as cracks or breakage, which leads to a decrease in its insulation performance, thereby causing signal leakage and crosstalk. By increasing the bit error rate threshold of the optical fiber 7 cable, the increase in the bit error rate caused by the damage to the insulation layer 3 can be tolerated to a certain extent, avoiding the system from being too sensitive and unstable. The cutoff frequency of the filter is determined according to the absolute error of the transmission rate of the composite communication cable. Since the cable certification tester will gradually age after long-term use, its performance will change. , thereby affecting the accuracy of the equipment. By increasing the cutoff frequency of the filter, the filter can allow higher frequency signals to pass through, which helps to compensate for the high-frequency signal processing capability lost due to aging of electronic components. Signals containing high-frequency components can be obtained more accurately, thereby improving measurement accuracy. The duty cycle of the signal generator is determined according to the temperature rise rate of the test area. Since the electronic components in the test equipment consume electrical energy when working, part of the electrical energy will be converted into heat energy, causing the equipment to heat up, thereby causing the test environment temperature to rise. By reducing the duty cycle of the signal generator, the continuous working time of the equipment can be reduced without affecting the test task, thereby reducing heat accumulation and reducing the amplitude of the test environment temperature increase caused by equipment heating, thereby improving the test stability of the composite communication cable.

[0064] Specifically, the control module is used to obtain the transmission delay time of the test signal within a number of transmission cycles and calculate the average transmission delay time of the test signal. If the average transmission delay time of the test signal is greater than a preset first delay time, it is determined that the test stability of the composite communication cable does not meet the requirements;

[0065] The control module is used to preliminarily determine that the test accuracy of the composite communication cable does not meet the requirements when the average transmission delay duration of the test signal is greater than the preset first delay duration and less than or equal to the preset second delay duration, and to determine whether the test accuracy of the composite communication cable meets the requirements based on the absolute error of the transmission rate of the composite communication cable.

[0066] It can be understood that the three intervals divided by the preset first delay time and the preset second delay time correspond to three situations respectively:

[0067] The first interval is when the average transmission delay of the test signal is less than or equal to the preset first delay, corresponding to the situation that: it is determined that the test stability of the composite communication cable meets the requirements;

[0068] The second interval is when the average transmission delay of the test signal is greater than the preset first delay time and less than or equal to the preset second delay time. This occurs when the cable certification tester gradually ages after long-term use, causing performance changes that affect the accuracy of the device.

[0069] The third interval is when the average transmission delay of the test signal is greater than the preset second delay time. The corresponding situation is: due to preparation errors when installing the connector, the insulating layer 3 is damaged after being connected to the connector, such as cracks and breakage, resulting in a decrease in its insulation performance, thereby causing signal leakage and crosstalk.

[0070] In implementation, the preset first delay time length is generally selected from the range of [0.1 μs, 0.3 μs], and the preset second delay time length is generally selected from the range of [0.4 μs, 0.6 μs].

[0071] Preferably, the preferred embodiment of the preset first delay time length is 0.2 μs, and the preferred embodiment of the preset second delay time length is 0.5 μs.

[0072] Specifically, the average transmission delay duration of the test signal is the average time delay experienced by the signal from the transmitting end to the receiving end during the transmission process within a number of transmission cycles.

[0073] Specifically, the control module is used to increase the bit error rate threshold of the optical fiber 7 when the average transmission delay time length of the test signal is greater than the preset second delay time length;

[0074] The increase range of the bit error rate threshold of the optical fiber 7 is determined by the difference between the average transmission delay time of the test signal and the preset second delay time.

[0075] Specifically, when the difference between the average transmission delay of the test signal and the preset second delay time is within 0.1 μs, the bit error rate threshold of optical fiber 7 is increased by 1.1 times the original value; when the difference between the average transmission delay of the test signal and the preset second delay time exceeds 0.1 μs, the bit error rate threshold of optical fiber 7 is increased by 10% for every 0.1 μs exceeding the original value. -11 For example, the difference between the average transmission delay of the test signal and the preset second delay time is 0.3 μs, and the bit error rate threshold of the optical fiber 7 is 10 -10 The bit error rate threshold of the enlarged optical fiber 7 is 10 -10 ×1.1+10 -11×2=1.3×10 -10 .

[0076] During implementation, the system of the present invention determines the bit error rate threshold of the optical fiber 7 by setting a preset first delay time and a preset second delay time. Since the insulation layer 3 may be damaged after being connected to the connector due to preparation errors when installing the connector, such as cracks or breakage, its insulation performance is reduced, resulting in signal leakage and crosstalk. By increasing the bit error rate threshold of the optical fiber 7 cable, the increase in the bit error rate caused by damage to the insulation layer 3 can be tolerated to a certain extent, avoiding the system from being too sensitive and unstable, thereby improving the test stability of the composite communication cable.

[0077] Specifically, the control module is used to determine whether the test accuracy of the composite communication cable meets the requirements based on the absolute error of the transmission rate of the composite communication cable. If the absolute error of the transmission rate of the composite communication cable is greater than the preset first error, it is determined that the test accuracy of the composite communication cable does not meet the requirements.

[0078] Specifically, the control module is configured to increase the cutoff frequency of the filter when the absolute error of the transmission rate of the composite communication cable is greater than a preset first error and less than a preset second error.

[0079] Specifically, the control module is used to preliminarily determine that the test environment stability of the composite communication cable does not meet the requirements when the absolute error of the transmission rate of the composite communication cable is greater than or equal to the preset second error, and determine whether the test environment stability of the composite communication cable meets the requirements based on the temperature rise rate of the test area.

[0080] It can be understood that the preset first error amount and the preset second error amount are divided into three intervals, corresponding to three situations respectively:

[0081] The first interval is when the absolute error of the transmission rate of the composite communication cable is less than or equal to the preset first error, corresponding to the situation that: it is determined that the test accuracy of the composite communication cable meets the requirements;

[0082] The second interval is when the absolute error of the transmission rate of the composite communication cable is greater than the preset first error and less than the preset second error. This corresponds to the situation where the cable certification tester gradually ages after long-term use, resulting in performance changes that affect the accuracy of the device.

[0083] The third interval is that the absolute error of the transmission rate of the composite communication cable is greater than or equal to the preset second error. The corresponding situation is: since the electronic components in the test equipment consume electrical energy when working, part of the electrical energy will be converted into heat energy, causing the equipment to heat up, thereby causing the test environment temperature to rise.

[0084] In implementation, the preset first error amount is generally selected from the range of [475Mbps, 485Mbps], and the preset second error amount is generally selected from the range of [486Mbps, 496Mbps].

[0085] Preferably, the preferred embodiment of the preset first error amount is 480 Mbps, and the preferred embodiment of the preset second error amount is 490 Mbps.

[0086] Specifically, the absolute error of the transmission rate of the composite communication cable refers to the difference between the actual data transmission rate and the target rate.

[0087] Specifically, the increase range of the cutoff frequency of the filter is determined by the difference between the absolute error of the transmission rate of the composite communication cable and a preset first error.

[0088] Specifically, when the difference between the absolute error amount of the transmission rate of the composite communication cable and the preset first error amount is within 5Mbps, the cutoff frequency of the filter is increased to 1.2 times the original amount. When the difference between the absolute error amount of the transmission rate of the composite communication cable and the preset first error amount exceeds 5Mbps, on the basis of being increased to 1.2 times the original amount, the cutoff frequency of the filter is increased by 5MHz for every 2Mbps exceeding. For example, the difference between the absolute error amount of the transmission rate of the composite communication cable and the preset first error amount is 7Mbps, the current cutoff frequency of the filter is 30MHz, and the cutoff frequency of the filter after increase is 30×1.2+5×1=41MHz.

[0089] During implementation, the system of the present invention determines the cutoff frequency of the filter by setting a first error amount and a preset second error amount. Since the cable certification tester will gradually age after long-term use, resulting in performance changes, which in turn affects the accuracy of the equipment, by increasing the cutoff frequency of the filter, the filter can allow higher frequency signals to pass through, which helps to compensate for the loss of high-frequency signal processing capabilities due to aging of electronic components, and can more accurately obtain signals containing high-frequency components, thereby improving measurement accuracy and further improving the test stability of composite communication cables.

[0090] Specifically, the control module is used to determine whether the test environment stability of the composite communication cable meets the requirements based on the temperature rise rate of the test area. If the temperature rise rate of the test area is greater than a preset rise rate, it is determined that the test environment stability of the composite communication cable does not meet the requirements, and the duty cycle of the signal generator is reduced;

[0091] The reduction range of the duty cycle of the signal generator is determined by the difference between the temperature increase rate of the test area and the preset temperature increase rate.

[0092] It can be understood that the preset increase rate is divided into two intervals, corresponding to two situations:

[0093] The first interval is when the temperature rise rate of the test area is less than or equal to the preset rise rate, corresponding to the situation that: it is determined that the test environment stability of the composite communication cable meets the requirements;

[0094] The second interval is when the temperature rise rate of the test area is greater than the preset rise rate. The corresponding situation is: since the electronic components in the test equipment consume electrical energy when working, part of the electrical energy will be converted into heat energy, causing the equipment to heat up, thereby causing the test environment temperature to rise.

[0095] In practice, the preset temperature increase rate is generally selected in the range of [1°C / h, 5°C / h].

[0096] Preferably, the preset increasing rate is 3° C. / h.

[0097] Specifically, the temperature rise rate of the test area refers to the value of the temperature rise of the test area per unit time.

[0098] Specifically, when the difference between the temperature rise rate of the test area and the preset rise rate is within 0.5°C / h, the duty cycle of the signal generator is reduced to 0.9 times the original value. When the difference between the temperature rise rate of the test area and the preset rise rate exceeds 0.5°C / h, on the basis of being reduced to 0.9 times the original value, the duty cycle of the signal generator is reduced by 2% for every 0.5°C / h that exceeds. For example, if the difference between the temperature rise rate of the test area and the preset rise rate is 2°C / h, the current duty cycle of the signal generator is 60%, and the duty cycle of the signal generator after reduction is 60×0.9-2×3=48%.

[0099] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
