Introduction of optical fiber networking method

  Optical fiber networking is one of the key technologies to build a modern communication network, and its methods are diverse, which can be selected according to different application scenarios and requirements. The following are some common optical fiber networking methods:in other words fiber optic patch cord It is possible to develop in a good direction, and there are still many places worth looking forward to in the future. https://www.fibercan-network.com/

  

  Point-to-point (P2P) connection:

  

  This is the most basic networking mode, and two nodes are directly connected through an optical fiber. Suitable for simple connections, such as server connections within a data center.

  

  Star topology:

  

  In a star topology, all nodes are directly connected to a central node, usually an optical switch. This method is convenient for management and troubleshooting, but if the central node has problems, the whole network will be affected.

  

  Ring topology:

  

  Nodes form a closed ring, and data is transmitted in sequence on the ring. If a node or optical fiber fails, data can be bypassed by another path, which improves the reliability of the network.

  

  Mesh topology:

  

  There are many optical fiber connections between nodes, forming a complex network. This method provides a high degree of redundancy and reliability, but it also increases the complexity and cost of the network.

  

  Bus topology:

  

  All nodes share an optical fiber as the communication medium. This method is simple, but when the number of nodes is large, signal collision and data loss are easy to occur.

  

  Wavelength division multiplexing (WDM):

  

  Through wavelength division multiplexing technology, optical signals with multiple wavelengths can be transmitted on the same optical fiber at the same time, which greatly increases the transmission capacity of optical fiber.

How to Adjust the Car Seat Headrest

  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.After that, car head neck pillow Not afraid of the future, dare to fight and fight, and won applause again and again in the 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.

A few facts about watches

  Today, I will talk to you about the cold knowledge of the watch world, and we will enter the theme directlyFor these reasons, I think mechanical watch The situation is still optimistic, and the market is still in a blue ocean stage. 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.

Beware of international shipping traps. How to choose a reliable shipping company

  I don’t know when it started, but when I searched for international express delivery on a certain book, I saw all the ads holding signs saying “XX from China, 10KG = 38 yuan, regardless of whether it is ordinary or not.”For the immediate pressure, shipping agent With its own coping style, it can break the predicament and usher in a new life through the quality of the product itself. https://www.freeseaship.com/

  

  On average, this means less than two yuan per pound. Do you have any idea whether you can get this price?

  

  0.jpg

  

  Let’s think about it first. This price is impossible even in China, let alone international express delivery. Is it possible?

  

  Secondly, families should know that international express delivery does not distinguish between sensitive goods and general goods.

  

  In terms of cost alone, sensitive goods are higher than general goods. The fear is that you will be warmly received at the beginning, but then turn your back on them.

  

  00.jpg

  

  Then there may be such a situation: you don’t find such a shipping company, but you still fall into the trap. How should you avoid these pitfalls?

  

  Family members have done their homework, and the key points are as follows! !

  

  international shipping

  

  1. Check the business license

  

  Whether a company is operating in compliance can be determined by checking the company’s qualification certificates, such as whether it has international freight forwarding qualifications and other permissions.

  

  2. Be wary of ultra-low prices

  

  International express delivery costs cannot be much lower than the market price. Too low quotes often hide traps

  

  There may be other charges, such as packaging fees, photo fees, etc., and there may even be extremely expensive additional weight prices, which are more expensive than the generally advertised 60 yuan per kg. Don’t try it at the cost of losing more for a small price. It’s not worth it.

  

  3. Whether the price is clearly marked

  

  See whether the fee is charged according to the quotation form. Many companies often start charging various fees after the user places an order to the warehouse: handling fees, material fees, labor fees, etc.

  

  4. Is there an official website system?

  

  Generally, regular shipping companies have their own official website systems. Global Express not only has its own official website but also has a mini program. All package information can be checked, and there will also be exclusive customer service to follow up.

  

  5. Pay attention to surcharges

  

  Pay special attention to surcharges, which may be more expensive than the freight in a few minutes! You must ask clearly what surcharges there are before placing an order.

  

  6. Keep evidence

  

  When communicating with the shipping company, keep chat records, quotations, contracts and other evidence in case of emergency.

  

  Dear family members, don’t be greedy for small profits. Be sure to keep your eyes open before sending express delivery! After all, it’s all money!
