Every day, visiting Aunt Zhang has also been visiting for some years. By starting with the Amazon's latest entry-level Kindle 558, also specifically asked my colleagues to take care of a good Kindle 3 to do the next comparison (Mobile phone slag quality warning -.-) Scheduled three days in advance, was originally expected to ship on the 20th, delivery on the 21st, did not expect 19 on the evening to receive delivery SMS, 20 was lying in the office early in the morning First of all, Amazon ancestry kraft paper bag packaging Open up and reveal the recently updated Kindle blue box On the back, the features are all identified. The memory upgrade from 256 of the original 499 models to 512 has not been written out. Seal release! A card is still a bit amazing, the border is narrower than the previous generation 499, but how to bring the data line to the mess lying in the box, obsessive-compulsive disorder can not be tolerated! Initial boot screen The back is flat, the edge feels more like the current ipad, the grip is a bit sleek, a bit slippery! ! ! Wifi shared to Amazon -. - The people who do not know the truth say that they are not checked It's not as long as the iphone 6. If it's wide, the boys can master it. The girls can't catch it. Dictionary function is very easy to use! Where will not turn where Inside the machine, it's okay to close the advertisement. (The first time you started the Kindle, you used to hear that you need to find a customer to close the advertisement.) ------------------------------------------------ The following is Kindle 3 Comparison ---------------------------------------------- At the same time open the national comics: Slam Dunk Compared to the following: Kindle 3 graphics display is better than 558, 558 reading books to see the comic color is a bit too deep, see a little loss of detail Many years ago the Kindle 3 and the current 558 are comparable in thickness! Finally, summarize the advantages and disadvantages of the 558: advantage: Invincible price/performance, the Kindle is the most affordable one; Compared with the previous 449 to be more light and thin, the border is also narrow, personally feel that the value of the face has become higher; Now that the price of a physical book is between 20 and 30, I don't think I usually read 20 books after reading a book. I think it is a habit of reading. Disadvantages: After the light and thin, the relative sacrifice is a certain feel, the border is very rounded, one hand holding very slippery! ! ! The entry money is old, there is no backlight, and at home the first time I use it under the lamp at night, it's so dark. - In conclusion: Books are valuable and knowledge is priceless. I hope everyone has their own reading habits. Thank you.
Optical fiber fusion splicer is mainly used for the construction and maintenance of optical cable in optical communication, so it is also called optical cable fusion splicer. The general working principle is to use a high-voltage arc to melt the sections of the two optical fibers while using a high-precision motion mechanism to gently advance the two optical fibers into one, so as to realize the coupling of the optical fiber mode fields.
Optical fiber fusion splicer is mainly used in: Splicer Fusion,Ftth Splicing Fusion Splicer,Optic Fiber Splicing Machine,High Precision Splicer Fusion Machine Shenzhen Scodeno Technology Co.,Ltd , https://www.scodenonet.com
Construction, maintenance and emergency repairs of optical cable lines of telecommunications operators, communication engineering companies, and public institutions;
Experiment, production and testing of optical devices;
research;
Teaching and research related to optical fiber communication in major colleges and universities.
Ordinary optical fiber fusion splicers generally refer to single-core optical fiber fusion splicers. In addition, there are ribbon optical fiber fusion splicers specially used to splice ribbon optical fibers, sheath fusion splicers for splicing sheathed optical cables and jumpers, and splice protection Polarization maintaining fiber fusion splicer for polarized fiber, etc.
According to different alignment methods, fiber fusion splicers can be divided into two categories: cladding-aligned and core-aligned. The cladding alignment type is mainly suitable for occasions such as low-requirement fiber to the home, so the price is relatively low; the core alignment type fiber fusion splicer is equipped with a precision six-motor core alignment mechanism, a specially designed optical lens and software algorithms, which can Accurately identify the fiber type and automatically select the matching splicing mode to ensure the splicing quality. The technical content is high, so the price will be relatively high.
