What does it mean for RJ45 connectors to have different colored lights?

The RJ45 connector also has some gigabit network card lights color-coded. If it doesn't light up, it means 10M/green means 100M/yellow means 1000M now the 10M network is almost invisible, if a long light is on, it basically says 100 megabytes or more, and the other light flickers, which means there's data coming and going, depending on your network device. There are even low-level network cards such as TP-Link, which only have one light, and the light represents connectivity, and the flicker represents data transceiver, so the RJ45 network connector with the light allows us to better distinguish between the data conditions of the network connection, at the same time, the RJ45 connector with light is not very high cost, we consider all aspects of life, with light RJ45 connector is a good choice.

Most network interfaces have a green light for network speed, and a yellow light for sending and receiving data. Each network card, each switch, routing light cat, digital TV and other network equipment, although they are not the same, but generally speaking: green light divided into bright or not bright, yellow light divided into flashing or not flashing (on behalf of whether there is data sent and received) . Green Light: Long Bright, on behalf of 100m; not bright, on behalf of 10M Yellow Light: long bright, on behalf of no data sent and received; flashing, on behalf of data sent and received
