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.

1. The steps of fiber optic construction Fiber optic is composed of extremely pure quartz glass, laying and construction should consider the same matters as the cable project. However, fiber optic resistance to tension, torsion, bending, lateral pressure resistance, poor performance, easy to break,

Pre-stranded suspension clamps are used for the connection of ADSS fiber optic cable, OPGW fiber optic cable and other wires in the linear tower, in power engineering, the use of pre-stranded suspension clamps can well protect the fiber optic cable, there is an auxiliary role of vibration damping

Introduction to wire management process 1 waterfall styling This is a relatively ancient wiring model, and traces of it can still be seen sometimes. It adopts the artistic image of "water curtain hole", directly hangs the twisted pairs from the module of the distribution frame

Why need use patch panel? 1、From the design point of view Comprehensive wiring has a point requirement I wonder if you have noticed, that is, the information point requires data, voice points can be interchanged when necessary

In our daily work, study, Internet process often encounter network card, slow, intermittent phenomenon, enterprise information center or network center often receive such complaints, that the network fault is caused by what? This is a very complicated matter, but also a headache to solve, especially
