In optical fiber installation, accurate measurement and calculation of optical fiber links is a very important step to verify the integrity of the network and ensure the performance of the network. The optical fiber will cause obvious signal loss (that is, optical fiber ...

Understanding the performance of optical fiber and copper wire can make a better choice, then what characteristics do optical fiber and copper wire have? 1. Copper wire characteristic Copper wire In addition to the above mentioned good anti-interference, confidentialit...

Can single-mode fiber and multi-mode fiber be mixed? Generally, no. The transmission modes of single-mode fiber and multi-mode fiber are different. If the two fibers are mixed or directly connected together, link loss and line jitter will be caused. However, single-mode ...

The basic structure of optical fiber is generally composed of outer sheath, cladding, core, and light source. Single-mode fiber and multi-mode fiber have the following differences: Sheath color difference: In practical applications, the outer sheath color of the fiber ca...

Also known as software-defined Wide area networks, SD-WAN has become one of the hottest topics among enterprise network operators and service providers. Why does this happen? On the one hand, an increasing number of Internet-based applications, services and intensive app...

When the PoE power supply fails, it can be investigated from the following four aspects. • Check whether the receiving end device supports PoE power supply. Since not all network devices can support PoE power technology, check the equipment for POE power technology befor...
