　　[Keywords:” target=_blank> Optical fiber communication technology; Application development trend

　　The application of optical fiber communication technology mainly includes: using light wave as information carrier to realize communication function; Use optical fiber as a continuous propagation medium. At present, in terms of information communication, optical fiber communication belongs to the fourth generation communication mode. Its main characteristics are: light weight, fast propagation speed, small loss and small size, and its transmission frequency band is very wide, which can effectively resist most electromagnetic interference. These advantages make optical fiber communication gradually become the mainstream of society. At present, optical fiber is installed in most communication fields in China, and related businesses are still expanding, which has been recognized by more and more production and service fields. Understanding and studying the specific application of this communication technology can promote the development of informatization in China.

　　1 optical fiber communication technology

　　The so-called optical fiber communication is the optical fiber communication, which effectively transmits signals through optical fiber to achieve the purpose of information transmission. We can regard this optical fiber communication as an optical communication method with optical fiber as the medium [1″ target=_blank>. Among them, the main components of optical fiber are: coating, fiber core and cladding, while the inner core is usually only a few tens of microns or even a few microns, and its diameter is smaller than that of hair; Cladding is the middle layer, and the optical signal can be totally reflected in the fiber core by using the difference of specific refractive index between the fiber core and cladding, that is, the optical signal can be transmitted; Among them, the coating is mainly to improve the toughness of optical fiber, so as to protect optical fiber from damage. There is not only one light in the optical fiber communication system, but a large number of optical fibers are gathered together to form an optical cable. The reason why this kind of optical cable composed of a large number of optical fibers can transmit huge information in a unit time is mainly because the optical frequency of this optical cable is very high and the optical fiber transmission frequency band is very wide, so its transmission capacity is relatively large. The advantages of this optical fiber communication technology include: relatively small volume, very light weight, very few metal materials, strong electromagnetic interference resistance and radiation resistance, very good confidentiality, anti-eavesdropping, wide frequency band, good anti-interference performance, low price, etc. At the same time, the source of light materials used is very rich, which can reduce the application of many non-ferrous metals, and the diameter is very small and not heavy.

Especially in metropolitan communication, local communication and international communication industries, optical fiber communication technology has been widely used [2″ target=_blank>. At the same time, the optical fiber communication technology is constantly expanding and has become a very key technology in the communication field, which has effectively promoted the further development of the entire communication industry.

　　The correct use of car safety seats is essential to protect the life safety of drivers and passengers. In this article, Shanghao car headrest manufacturer will introduce in detail how to correctly adjust the seat angle and headrest height to minimize injuries in the event of a vehicle collision.In combination with these conditions, car head neck pillow It can still let us see good development and bring fresh vitality to the whole market. https://www.sanlead.cc

　　Adjustment of seat angle

　　. The importance of seat angle

　　The seat angle is essential for the comfort and safety of drivers and passengers. The correct seat angle can ensure that the driver maintains a good line of sight and operating space during driving, and also helps to reduce the injury of passengers in the event of a vehicle collision.

　　. How to adjust the seat angle

　　First, the driver should adjust the height of the seat so that the feet can easily step on the accelerator and brake pedals, while maintaining a certain degree of curvature between the knees and the seat. Then, the driver should adjust the front and rear position of the seat so that the arms can naturally stretch to the steering wheel while keeping the back close to the seat back.

　　Next, the driver should adjust the angle of the seat so that the back is as upright as possible. The flatter the angle between the head, neck, and body, the less likely it is to cause injuries to occupants during a collision. You can adjust the seat angle using the lever or electric button located under the seat.

　　Today, I will talk to you about the cold knowledge of the watch world, and we will enter the theme directlyfor a long time diving watch It has an extraordinary development speed, and I believe that the future will be as overwhelming as ever. https://www.supertimewatch.com/

　　Why are watch ads 10:10?

　　You can pay attention to the advertising output of the watch brand, most of the watch Pointers are staying at about 10:10, there are two main statements for this problem.

　　watch facts

　　On the one hand, if you look at the watch from an aesthetic point of view, showing the hands at 10:10 is the most coordinated and symmetrical for the entire picture.

　　watch facts

　　Another is that the hour and minute hands stop at about 10:10 this time point, you can avoid most of the brand logo of the watch, and most of the functions displayed on the watch.

　　watch facts

　　The next time you look at the watch advertising chart or the watch exhibition, you can pay attention to the details of the time stay.

　　watch facts

　　Second, the definition of the watch factory date

　　I want to share this mainly because I often see that when you buy second-hand Rolex, you always worry about when the factory date of the watch is.

　　watch facts

　　In 2012, Rolex began to stop all of its watches labeled with the so-called year, and it was displayed by 8-code numbers + numbers (garbled).

　　So in 2012 after the factory Rolex, outsiders do not know the real factory year or factory date.

　　Only Rolex original factory check the serial number will know the real so-called “factory day”, when you buy you can ask the business when this table is into the goods.

　　In the watch world is not Rolex just so, the basic all brands are so, that the so-called factory date definition in the end is what?

　　For the movement and the case from different watchmaking factories, how to define the so-called factory. To say that the moment from the movement into the case is called the factory date, I think it is inappropriate.

　　The heart of a watch is its movement, and the warranty content and scope of most watch brands are probably the internal warranty of the movement, so the moment the movement is assembled, it should be the so-called factory date.

　　However, the movement is assembled to really put into the case, during which there is a long time to adjust and test, and the moment of assembly is actually not a completely accurate factory date.

　　Like ETA’s movement 7750, 2892, etc., these relatively popular movements have an annual output of tens of thousands of units, and have actually been assembled to the hands of consumers for several years.

　　For example, you buy a Rolex in 2017, but it may be in 2014, 2015, or even earlier, Rolex has been tested, after the test will be sent to the agency, and then sold to consumers.

　　This period is actually a very long period of time, which is why the warranty of the watch is recognized by the date of the card, which is almost the same as buying a car~

　　Three, how to put the chain strap watch?

　　This is a controversial topic, and people have different opinions about it. I’m going to say two of them here, and see which one you tend to prefer.

　　watch facts

　　1, if you want to put the chain strap watch down, it must be placed sideways, and to avoid the position of the head, that is, the opposite direction of the head, the main reason for this is to fear that the watch head will be oppressed for a long time.

　　watch facts

　　The head is a relatively fragile part, if the side for a long time to hold it, may lead to the damage of the head core.

　　watch facts

　　2, the second argument is the grapevine, heard that many large watch factory teachers also agree with this argument, that is, the head of the watch must face down.

　　watch facts

　　Because the area of the head in contact with the surface is relatively small, the head is placed downward to avoid scratches on the watch to the greatest extent.

　　watch facts

　　The key point is that from a watch technician’s point of view, when the watch is maintained, the head can be replaced separately, that is to say, even if you scrape the head and damage the core, it can be replaced separately.

　　If the side of the watch is scratched, it is not very good to deal with, after all, the case is rarely replaced, so I would rather change the head core, rather than change the case.

　　Two statements, different supporters, you can evaluate for yourself which one is more acceptable.

　　LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and indicator lights. Compared with traditional light sources, LED light sources have large differences in physical size, luminous flux, spectrum, and spatial distribution of light intensity. Therefore, LED detection cannot replicate the standards and methods of traditional light source detection.

　　What Are the Most Common Detection Technologies for LED Headlights?

　　Detection of optical parameters of LED lamps

　　1. Luminous intensity detection

　　Light intensity is the strength of light, which is the amount of radiated light within a certain angle range. Since LED light is relatively concentrated, the inverse square law does not apply at close distances. Therefore, the CIE127 standard stipulates that the conditions for measuring light intensity are A (far-field conditions) and B (near-field conditions) for measuring the average normal light intensity. The detector area for both conditions is 1cm2. Generally, standard condition B is used to measure luminous intensity.

　　2. Luminous flux and light efficiency detection

　　Luminous flux is a physical quantity that measures the total amount of light emitted by a light source. It represents the sum of the light energy emitted by the light source in all directions. There are two main methods for detecting luminous flux:

　　Integral method: Light the standard lamp and the lamp under test in the integrating sphere in turn, and record their readings on the photoelectric converter as Es and ED respectively. The luminous flux of the standard lamp is known as Φs, then the luminous flux of the lamp under test ΦDED〜Φs/Es. The integral method uses the principle of “point light source” and is simple to operate, but it is affected by the color temperature deviation between the standard lamp and the lamp under test, and the measurement error is large.

　　Spectrophotometry: This method calculates the luminous flux by measuring the spectral energy distribution of the light source \( P(\lambda) \). Use a monochromator to measure the spectral energy of the standard lamp in the wavelength range of 380nm to 780nm on an integrating sphere, and then measure the spectral energy of the lamp under test under the same conditions. By integrating these spectral energy values, the luminous flux of the lamp under test can be obtained.

　　Luminous efficiency is a parameter that describes the efficiency of a light source. It is defined as the ratio of the luminous flux emitted by the light source to the electrical power it consumes. For LED light sources, constant current is usually used to measure luminous efficiency to ensure the accuracy and repeatability of the measurement.
