1, the entrance of the optical cat is the optical fiber port, and the blue optical cable is the optical fiber port as shown below.

2. The outlet of the light cat is a network cable, and the yellow network cable in the above picture is the outlet of the light cat.

3. The two voice ports on the light cat can be connected to the fixed telephone.

4. After the fiber cat is connected correctly, you can test the Internet. Generally, the installer will directly use the laptop to test online.

The working principle of optical fiber cat is that when the optical fiber is connected to the optical fiber, if the signal is normal, the optical fiber cat will automatically communicate with the upper computer room switch (olt equipment) and send the serial numbers of the optical fiber cat equipment (each unique) to the olt. After communicating with the network management of the computer room, the maintenance personnel report the serial number of the equipment to the network management. After the network management finds the optical fiber cat under the port in the olt, it confirms the equipment and issues the data applied by the user.

Therefore, each port of optical fiber cat is defined by the operator's computer room. If users want to use it, they must apply to the operator's business hall. (However, local operators will decide to open one or two Ethernet ports according to local conditions, and the extra ones will not be released).
