When an optical fiber is stretched beyond its tensile limit, it breaks. The fiber optic cable structure increases the strengthening member, the fiber optic cable required tensile strength, mainly by the strengthening member to bear. In the process of construction, the traction should not exceed the

If you want to ask the foreign trade industry bosses are most concerned about the problem, then customer conversion rate must be an unavoidable topic. Foreign trade customer development has the characteristics of long transaction cycle, complex transaction process, large personnel changes . Limited

How to deal with your“Zombie” customers, we often encounter the daily work of collating and analyzing customer data, we will be based on customer activity, customers will be divided into zombie customers and active customers. An active customer is a customer who responds effectively when we have a b

Modular Plug is the basic network product, but it can determine the transmission speed of the entire network line. Do you know how to distinguish the good or bad Modular Plug?Main determinants：The factor that determines the quality of the Modular Plug is whether the glue material is of high quality.

Because the cable has good insulation performance, the importance of lightning protection cable is often ignored. The lightning protection of optical cable line is a key technology related to line safety which should be paid attention to in the whole process of route survey and design to engineering

The excess length of the communication optical fiber is the key to the process control in the production process of the plastic sleeve process. The so-called excess length is the percentage per thousand of the difference between the length of the optical fiber and the length of the loose tube and th

1, OPGW cable particularityThe optical fiber of OPGW cable is placed in the ground wire of the overhead high-voltage transmission line, which is used to form the optical fiber communication network of the transmission line, and provides communication channels for the power network, such as protectio

In order to accurately measure fiber length and decay when using OTDR, the relevant parameters must be set correctly before starting the test. The main parameters are: refractive index, pulse broadband and average time; At the same time, how to use the cursor to accurately pick points is also crucia

With the proposal of the concept of Internet +, the demand for transmission bandwidth of emerging businesses represented by the Internet service industry has increased sharply, and the capacity of the man transmission system also needs to be improved.
