RJ45 connector LEDs are divided into green and yellow lights, the two colors of the light have different roles but most people do not know.

RJ45 connector network interface green and yellow lights have different uses, most of the network interface LED green light represents the speed of the network, while the LED yellow light represents the data sent and received.

Although network devices such as NICs, switches, routers, optical modems, and digital TVs are different, generally speaking, the green light is divided into on or off, and the yellow light is divided into flashing or non-flickering (representing whether there is data transmission and reception).

Green light: long light represents 100M, no light represents 10M

Yellow light: long light represents no data transmission and reception, flashing represents data transmission and reception.

The RJ connector also has some gigabit NIC lights which are distinguished by color, no light means 10M, green means 100M, yellow means 1000M.

Few people use the 10M network nowadays. If one light is always on, it basically means that the network is 100M or higher, while the other light flashes from time to time, which means that data can be sent and received normally. The specific need depends on the personal network equipment.

So that the RJ45 network connector with lights allows us to better distinguish the data situation of the network connection, in fact, the purchase cost of RJ45 connectors with LED lights and no LED lights are not very different from the cost, from the point of view of cost effectiveness, RJ45 connectors with LED lights is a good choice.
