What should I do if the optical signal of the broadband optical modem keeps flashing red?

If the LOS light on the optical modem turns red or flashes, it is generally faulty, as follows:

1. There is a problem with the optical interface of the optical modem, and the optical modem needs to be replaced.

2. The indoor pigtail connection optical cat connector is loose, and the connector can be restored by plugging it in;

3. The bending of the indoor part of the optical fiber is too large. Excessive bending of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, as long as the optical fiber is straightened;

4. If the optical fiber of the outdoor part is broken or the optical port of the equipment in the computer room is faulty, it is necessary to report the broadband fault, and there will be staff to come to the door to troubleshoot the fault after the fault report.

The optical signal flashes red, indicating that the fiber-optic modem cannot receive the signal. The general reasons are:

1. The optical fiber fusion at the joint does not fit the plate or is broken;

2. The cold connector at the light splitting right box is not plugged in well or the cold connector is broken;

3. The connector at the optical box is not plugged in;

4. Somewhere in the line is damaged or broken, etc.

In general, users with this kind of failure cannot repair it by themselves, and they need specialized personnel and fiber optic tools, so it is recommended to call the network operator to report the repair.

How to deal with the light signal of the optical modem keeps flashing red light Ultra-clear.

If the optical signal of the optical modem keeps flashing red, then the optical fiber is more likely to be broken, so it is recommended to restart the optical modem, check whether the fiber interface crystal head is loose, and plug in the connector tightly. If it still can't be solved, you can call broadband customer service** to report for repair.

The reason why the light signal of the optical modem keeps flashing red light:

1. Optical fiber break (more likely).

2. The optical fiber pigtail is not inserted into the optical modem (check it yourself).

3. Optical modem failure (small possibility).

4. Failure of the uplink splitter (generally this kind of failure, the neighbors around you can't use it.) As long as you are sure that the pigtail behind the optical cat has been connected correctly, you can only report it for repair and let the master come to check it.

It is recommended to follow the following steps:

1. Restart the modem. Turn off the power of the modem and the router and wait 5-10 minutes for the router to restart and check whether the situation recovers.

2. Check whether the crystal head of the optical fiber interface is loose and plug in the joint. Check whether the fiber cable (usually a yellow soft wire) behind the fiber modem is folded or squeezed, and straighten the cable with a little force to see if the red light situation returns to normal.

3. If the above methods still cannot be solved, you can call broadband customer service** to inquire whether there is a large-scale fault or power outage in the current area, and inform the customer service that the broadband used cannot be used and report for repair. Wait for the staff to come to the door for repairs.

The light signal flashes red light, which means that the light signal is interrupted, and the reasons and solutions are as follows:

1. If the indoor pigtail connection optical cat connector is loose or the contact is poor, in this case, you need to remove the interface and clean it up and then plug it back in.

Second, the bending of the indoor part of the optical fiber is too large. Excessive bending of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, as long as the optical fiber is straightened;

3. If there is a problem with the optical interface of the optical modem, this situation is a hardware problem of the optical modem, and the only way to repair the optical modem is to send the optical modem to customer service or replace it with a new optical modem.

Fourth, broadband arrears: Broadband services are basically postpaid models, and operators will close broadband services due to customer service arrears for too long, in which case only need to pay off the arrears.

Different fiber access technologies have different application scenarios:

Active optical access technology is suitable for enterprises and institutions with large bandwidth requirements and high communication confidentiality. It can also be used in feeder and distribution segments of the access network and mixed with other access technologies based on wireless or copper transmission.

ATM PON can be used to solve the access of enterprise users and residential users. Some operators use the "ATM PON XDSL" hybrid access solution to solve the broadband access of residential users or enterprise users.

In general, there are the following reasons for this problem:

1. The failure of the optical modem itself and the partial damage of the optical receiver will also cause this phenomenon.

2. Some optical fibers are bent too much, and the bending of optical fibers will affect the total reflection transmission of optical signals in the optical fiber, resulting in unobstructed signals.

3. If the server fails, such as server maintenance, it will cause a red light, and you can call the network operator** for repair.
