1. Engineering design, construction and maintenance work should be used in the same characteristics of high-quality optical fiberTry to use the same batch of high-quality optical fiber on a line. For the same batch of optical fiber, its mode field diameter is basically the same, the fiber at a certa

Coaxial line and optical fiber line are two kinds of transmission media widely used in modern communication field. They have their own unique advantages and characteristics.The transmission principleCoaxial line is a kind of transmission line covered by a conductor and a layer of insulating material

The general procedures for handling submarine cable incidents are as follows:1. The spread spectrum time domain reflectometer (SSTDR) is also used to locate the fault location. The instrument uses the principle of time-domain reflection. It transmits and receives a set of signals first, because a ca

Most people get Fluke test reports in hard copy or PDF files, often ignoring the most valuable test data, the paper version of the test report or the PDF version of the test data can basically see only the test results, pass or fail, and a very small portion of the test data (less than 1% of all the

As trading friends know, if a foreign customer can come to the company to discuss business, the chances of doing business will be great. Therefore, many foreign traders attach great importance to the visits of foreign customers, and when foreign customers to visit the company, how to correctly recei

Why do you visit clients? The customers here include partners and non-partners.01 customers choose the factory for their own difficult Chinese factories too much, the fierce competition, customers difficult to choose the factory for their own, coupled with the unauthenticity of the network, you are

Fiber optic network speed is indeed fast, long-distance transmission, can achieve the real one gigabit network speed. So, in our home LAN, between the computer and the router, why not use optical fiber to connect? Well, some people compare optical fiber to a highway, the home LAN to a small village,

In the modern communication industry, communications, optical fiber transmission technology as a kind of common information data transmission mode, since it has advantages of high efficiency and high transmission speed, communication quality, greatly satisfy the demand of modern social development,

I've written a lot about how customers look at factories, but mostly I've focused on the small details of how to receive customers, because I think most factories are familiar with receiving customers. But many new factories, new foreign trade enterprises into a misunderstanding. When presented to c

Optical Optical Time-domain reflectometer (OTDR) is a necessary optical fiber testing tool for analyzing the performance of optical fibers by using light backscattering technique. It can test fiber loss and locate breakpoints, splices, and connectors in fiber networks. However, there is a“Blind spot
