Security advantages of PoE switches ① The PoE switch can solve the problems of short circuit, excessive overload, voltage change, etc., and can provide good power supply protection. ②The standard PoE switch will provide a low-voltage detection terminal dev...

With the continuous development of PoE technology, PoE switches are currently in a very mature stage,however, due to the current monitoring market under the pressure of cost, the quality of the selected PoE switches or cables is too low, or the scheme design i...

Where are the application of single/multimode fiber and single/multimode optical module? (1) Single-mode fiber can make the fiber be directly transmitted to the center, and is generally used for long-distance data transmission; in multi-mode fiber, optical sig...

Fiber media converter can be divided into single-mode fiber and multi-mode fiber according to the transmission mode in the fiber. The most fundamental difference between single-mode  and multi-mode is the transmission distance. Industrial grade fiber media co...

Permanent failure:    For permanent faults, a loop can be used at one end, and the other end can be displayed from the switch or judged section by section and layer by layer with a transmission analyzer. 1. Transmission alarms appear in pairs. For example, i...
