What to Do When Fiber Distribution Box Malfunctions!

FTTH is what we call fiber-optic communication, which has now entered thousands of households and provides 100 Mbps or 1 Gbps network speeds for home internet access, making it easy to enjoy the benefits of the internet. However, what should we do if the fiber distribution box fails? What are the methods of dealing with it? In the following article, we will answer questions about the faults of the fiber distribution box and its solutions.

Identify the Fault of the Fiber Distribution Box

As a customer, we may know very little about fiber-optic communication technology, but we need to accurately describe some basic fault phenomena, such as not being able to access the internet, being able to connect to the internet but unable to open webpages, slow network speeds, and issues with the indicators of the home optical modem, such as a constant red light or a flashing green light, which can help troubleshoot and make an initial judgment.

The Fault of the Fiber Distribution Box May Be Caused by Home Computers

There are many possible causes of faults because providing customers with fiber-optic communication requires equipment rooms, fiber-optic converters, fiber-optic lines, user optical modems, user computers, or Wi-Fi routers, which involve many different devices and lines. Troubleshooting requires a step-by-step elimination process. Of course, with experience, we can quickly find the fault based on the fault phenomenon. If an FTTH connection fails, restart the computer first to check if the network is restored. This type of fault is easy to handle.

The Home Optical Modem is a Major Factor in the Failure of the Fiber Distribution Box

The fiber-optic line and computer are connected through the optical modem, which may have problems with settings or power and affect customer use. If your computer still has problems after restarting, you need to check this optical modem. First, look at the indicator lights of the optical modem. If all the lights are off, check the power status. You may need to replace the optical modem. If the lights are on, but different from usual, you can check the instructions for troubleshooting. Different brands of optical modems have different troubleshooting methods and should be handled according to the fault phenomenon, such as loose fiber-optic connections, device authentication failures, and fiber-optic line failures, which should be handled separately.

If the Fiber-optic Line is Not Working, Pass It Directly to the Service Provider for the Fiber Distribution Box

If the fault is found to be that the fiber-optic line is damaged and the network is not working, it should be passed directly to the service provider for repair. This may be due to problems with the fiber-optic line or fiber-optic distribution box. According to the relevant fault handling specifications, the field personnel of the service provider should be responsible for repairing it.

There Are Many Reasons Why the Fiber Distribution Box Restricts Internet Access

If you can connect to the internet but are restricted from playing games, watching videos, or chatting, you need to find the cause of the fault according to the actual situation. First, make sure that the computer's system and related software are working properly and are in a usable state. Then, professional technicians need to test the network data to find the cause of the fault.


First, contact the service provider immediately when a fault occurs.

Second, sometimes faults are caused by multiple reasons.
