With the speed of our network, many places are now using fiber optic network (network signal transmission medium “fiber” in the end what role), so the question arises, the use of fiber optic cat (network signal transmission medium “fiber” in the end what role) you only understand it? This section on the telecommunications fiber optic cats, hand to hand with you to explain, the other fiber optic cats are also similar.
The protagonist of this issue, the common “Telecom Fiber Optic Cat” appearance, the following figure
1, the above chart of those interfaces are for what do you understand?
1″, telephone (some are also called voice), is the phone line signal, or you can be more flexible to identify, the interface is smaller than other interfaces, and there are up to four iron or copper lines inside (only two lines on the phone is enough, four lines are spare and other roles);
2″, next to the two yellow interface a “network port 1”, one is “ITV”: network port 1 is connected to the computer, and ITV is connected to the TV; you can also be flexible identification, up to eight iron or copper wire (network TV, network) Generally is the need for four lines on it, the previous network TV can also be transferred with a telephone line is not needed now)
3″, reset: this is on behalf of the factory settings, because the device needs to be written in the manufacturer’s side of the program, otherwise the good hardware is no way to work, then, we want to use, some devices are required to set up, then the question arises? If: one day you “light cat” problems, such as entering the “light cat management interface” account password are forgotten (we generally do not need to remember these, as long as we do not restore the factory settings, pull the network cable staff will give you a good debugging), so do it? Is to press this button generally about 5 seconds to restore the factory state (factory state account password is generally written on the back of the device, or we professionals know the account password).
4″, in the past next door is inserted into the power socket, in the past next door is the “light cat” power switch.
2, well the following we will introduce the “light cat” indicator, their role is how, as follows.
Optical cat indicator
1″, the power light: as long as the light is generally only the power supply is not a problem.
2″, fiber optic, fiber optic signal, broadband lights: to light up and not red, but blue is generally normal.
3″, telephone, network port 1, network port 2 as long as the light is on, no red light is generally normal.
4″, summary: the general display of red and in the flashing, generally are faulty.
The following chart shows the status and meaning of the indicator lights.
