HYC Exclusive Patented Design  Polarization Maintaining(PM) Optical Fiber Connector
HYC Exclusive Patented Design Polarization Maintaining(PM) Optical Fiber Connector
What is Polarization Maintaining(PM) fiber?Theoretically, the fiber is a circular core which should not produce birefringence, and the polarization state in such a fiber will not change during transmission. In practice, there is always some external forces or other reasons which makes the fiber uneven or curved, and will cause a small amount of birefringence. When the fiber is subject to any external interference, such as wavelength, bending of the fiber, temperature and other factors, the polarization state of light will become chaotic when transmitted in polarization-maintaining fiber. Polarization Maintaining Optical Fiber (PM Fiber) is such a specialty fiber with strong birefringence that is generated by the design of optical fiber geometry. It can effectively solve the problem of polarization state change by eliminating the effect of stress on the polarization state of incident light. If the polarization of the light incident on the fiber is aligned with one of the birefringence axes, the polarization state will remain even if the fiber is bent. This polarization maintaining feature is extremely important for some special applications that require a polarized light input.How does the polarization maintaining (PM) patch cord work?Polarization maintaining(PM) patch cord maintains the coupling alignment of two Polarization modes by precise connector keys. Compared with the traditional optical fiber patch cord, the PM optical fiber patch cord has the advantages of polarization-maintaining optical fiber transmitting polarized light signal, keeping the direction of linear polarization unchanged, improving the coherent signal-to-noise ratio, and realizing high precision measurement of physical quantity. The polarization maintaining connector is an important component of two polarization maintaining fiber coupling, which ensures that the polarization mode of two PM optical fibers maintain the original polarization state of polarized light, and maintains a high extinction ratio for transmission. This requires precise docking of the slow or fast axes of the two fibers to minimize the angle error. By aligning the polarization direction of the polarized light with one of the axes, the polarization component assigned to the other axis is small, thereby maintaining the polarization state of the transmitted light. The polarization Angle and extinction ratio reflect the degree of polarization.360 ferrule rotation adjustable Polarization Maintaining(PM) optical fiber connectorTo meet the requirements of some special applications, HYC has developed a new type of polarization maintaining connector. HYCs exclusive patented design of this polarization-maintaining connector has a 360 ferrule adjustable. During the process of assembling, the polarization axis of fiber is aligned with the connector key by rotating the ferrule until the polarization axis is aligned with the connectors keyway. Compared with the traditional fiber adjustment method, it takes a shorter time to operate, which greatly improves the assembly efficiency. The polarization maintaining angle can be controlled within 1, and the high extinction ratio is maintained above 25dB. PM fiber patch cord products have the advantages of high precision, low loss, ultra-high extinction ratio, convenient manufacturing technology, high efficiency, higher maneuverability and patent protection, etc. They are widely used in many fields such as aerospace, navigation, unmanned driving system, communication, highly sensitive interferometer, poly-deviation wavelength division multiplexer, and other fields.HYC Co.,LtdHYCis a national Hi-tech optoelectronics company engaged in R&D, manufacture and marketing of fiber optical products. Providing professional product and service for fiber connectivity,WDM, PLC splitter and high density datacom cabling.

What Are the Methods of Cable Fault Detection
What Are the Methods of Cable Fault Detection
The fault types of power cable mainly include parallel fault and series fault. Series fault refers to the disconnection of multiple or one conductor in the cable. Usually, it is difficult to detect the series fault before disconnecting a conductor in series. It is easy to find the series fault only when there is a real short circuit. Parallel fault is caused by external insulation aging caused by cable overload operation for a long time, and then partial discharge, resulting in parallel fault. The cable fault different from the length difference and resistance value is broken down, and the cable fault can be divided into high resistance type, low resistance type and open circuit fault. So what are the methods of cable fault detection? Bridge method: bridge method is a traditional method of cable fault detection, which can achieve very ideal results. This method is convenient and fast with high detection accuracy. It belongs to a common cable fault detection method. However, due to the low bridge voltage difference and galvanometer sensitivity, it is only suitable for fault detection with small cable resistance. Moreover, it is difficult to detect the open circuit fault of equipment and cable with high resistance. High voltage bridge method: high voltage bridge method is a common fault detection method in cable fault detection. Its detection principle is that in the high-voltage bridge, when the constant current power supply pierces the cable, it will ensure a large bridge current to a certain extent, so as to form a certain potential difference on both sides of the overall bridge, so as to count the fault points on the basis of coordinating the bridge. This method is suitable for high voltage constant current power supply, and can effectively expand the detection range of high resistance of bridge. Relatively speaking, the result is more convenient and accurate. In addition, for the research theory of bridge method, the characteristics of cable centerline resistance and proportional distribution of the whole line can promote the formation of bridge detection system. Impulse high voltage flashover method: impulse high voltage flashover method is widely used in some methods of cable fault detection. The detection principle of this method is to apply impulse high voltage at the beginning of the faulty cable, so that it can quickly puncture the place where the fault occurs, and record the data information of voltage sudden change at the moment of the fault place. Through the analysis of wired fault point and wired initial data information, the time distance is tested, so as to obtain the fault location and uncertain countermeasures. Low voltage pulse reflection method: when low voltage pulse emission method is used to detect cable fault, low voltage pulse shall be injected into the damaged line. When the pulse is transmitted along the cable to the fault point, when the inappropriate impedance is encountered in the process of transmitting current, the reflected pulse is displayed on the detection device and reflected through the data record of the device, and then the round-trip time difference of the output pulse and the cable wave speed are calculated, so as to obtain the distance between the fault point and the test point. This method is very simple and can make the test results particularly significant. When it is difficult to determine the fault data, it can be detected directly. However, it also has disadvantages, that is, it is not suitable for high resistance fault and flashover fault. Secondary pulse method: for the secondary pulse method, it is effectively applied to form the impulse high-voltage pulse at the moment of the integrated high-voltage generator and introduce it to the cable fault location. On the premise of effectively piercing the fault location, it can prolong the uninterrupted time of arc formation at the fault location after breakdown. Obviously, it must be clear that at the same time, a trigger pulse can trigger the automatic trigger device of the secondary pulse and the operation of the cable detection instrument. On the basis of starting the automatic trigger device of the secondary pulse, two low-voltage pulses are transmitted. Through the device of forming the secondary pulse, the cable is effectively transmitted on the fault detection cable, so as to break down the cable. Using the cable fault detector, observe the floating characteristics of voltage waveform and the reflection wavelength in the whole process of forming arc, comprehensively and systematically record the screen of detection equipment, and distinguish various current fluctuations, one of which reflects the actual length of cable and the other reflects the actual distance of short-circuit fault.

Steps for Cable Fault Detection
Steps for Cable Fault Detection
The detection of cable fault generally goes through three steps: diagnosis, ranging and fixed point. 1. Cable fault nature diagnosis the diagnosis of cable fault nature, that is, to determine the type and severity of fault, so that testers can suit the remedy to the case and select appropriate cable fault location and fixed-point methods. 2. Cable fault location cable fault location, also known as rough measurement, uses instruments to determine the fault distance at one end of the cable. The common fault location methods at the test site include classical bridge method (high voltage bridge and low voltage bridge) and modern traveling wave method (pulse method: low voltage pulse method and high voltage pulse method). 3. Cable fault location cable fault location, also known as precise measurement, is to find out the general orientation of the fault point according to the fault location results and the path direction of the cable, and determine the accurate location of the fault point within a very small range by using the discharge acoustic measurement method or other methods. Generally speaking, successful cable fault detection must go through the above three steps, otherwise it will not be achieved if you want to speed up. For example, it is very difficult to detect the discharge sound at the fault point along a long cable path (possibly several kilometers long) without fault location. If the cable fault distance is known and a general orientation is determined, it is much easier to move the fixed-point instrument back and forth within a small range (about 10m) to detect the discharge sound at the cable fault point.

How to Quickly Locate Cable Faults
How to Quickly Locate Cable Faults
With the different cable laying methods, the difficulty of cable fault location is gradually increasing. Among them, the positioning and search of bridge, tunnel and open laying in ditch is relatively simple, and the positioning and search of direct burial is the most difficult. When the fault nature is simple, the special cable fault location equipment can be used to locate the fault within dozens of minutes. When the fault is special, it often takes 4-5 days or even longer to locate the fault. How to quickly locate cable faults? When using echo method for cable fault location, sometimes by transferring the fault phase and wiring mode, complex faults are often transformed into simple faults, and the fault location is quickly determined to win time for the emergency repair of on-site lines, which is of great significance to the power supply user department. Low voltage power cables are generally multi-core cables. After laying and continuous use, they generally show two core and multi-core phase to phase or phase to ground short circuit faults. Sometimes, when it is detected that the fault waveform collected by a core is not ideal, it can be considered to convert the wiring to other fault cores for fault waveform detection, which often has unexpected effects. The collected and detected waveforms will become more typical and regular, so the specific location of cable fault point can be determined quickly. During the long-term on-site measurement of cable customers, it is found that the fault of small cross-section copper core directly buried power cable (35mm2 and below) and aluminum core cable may be accompanied by short-circuit and wire breaking fault at the same time. During on-site detection, changing the short-circuit fault to wire breaking fault measurement according to the different fault nature of each fault core will often double everything with half the effort. For the medium voltage direct buried power cable with extruded armor as the inner lining, the fault is mostly caused by external mechanical damage. When the insulating core fails, the inner lining may have been damaged. In case of special cable insulation fault, it is difficult to collect waveform with professional cable fault instrument. It can be considered to use the acoustic method to apply the high-voltage pulse directly between the steel strip and copper shielding layer of the cable, which will often be fixed quickly. In the field measurement process, we also found that when using the acoustic measurement method to locate the fault point of low-voltage cable, when the high-voltage line and ground wire are connected between the bad phase and the metal shield or armor, the sound is very small, so the probe can not be used to listen to the fixed point, and the effect is not ideal. Through the actual listening side on site for many times, it is found that if the distance between the discharge ball gap is appropriately increased, and the high voltage and grounding wire are connected between the two phases of the fault, the discharge sound will become larger and the fault point will be determined quickly.
Working Principle of Cable Identification Instrument
Working Principle of Cable Identification Instrument
The working principle of the cable identification instrument needs to add a special signal to the identified cable, which should be received by a special receiver. Using this characteristic, the cable to be found can be identified. The cable identification instrument works according to the following principles: the cable identification instrument consists of a signal generator, a receiving clamp signal detector and an indicator. The signal generator mainly generates special pulse modulation signals, which are added to the stopped tested cable through the output line. The receiving clamp is used to find the tested cable on site. When the receiving clamp detector detects the special signal applied to the cable, The electric meter pointer on the signal detector swings synchronously with the frequency of the applied signal, while the signals detected on other cable lines are much smaller and in the opposite direction. It is easy to determine the tested cable by indicating the amplitude and direction of the electric meter. When the receiving clamp signal detector is used in combination with the signal generator, it can be used to distinguish the charged state of the cable, or assist in finding the short circuit position of the cable. When receiving clamp signal detector is used, clamp the cable with clamp.
