How to fix the red light of the telecom optical modem, and how to deal with the signal light of the

The optical signal light of the optical modem indicates the working status of the optical signal on the optical modem. Its work is related to the three parts of the machine room--- optical cable--- optical modem.

The light signal light red light or flashing mainly has the following aspects:

1. The light port of the computer room emits low or no light, causing the user's optical modem to work abnormally, and the optical signal light cannot receive the optical signal sent from the optical cable or the power of the optical signal is too low, which will cause the optical modem to shake hands with the computer room abnormally, and the optical signal will flash or alarm with a red light.

2. Optical cable failure (including broken optical splitter) will also cause the optical modem to not receive light or the light collection is too low, and the optical signal light will also flash or alarm with red light.

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

No matter which of the above three situations occurs, users basically can't solve it, and they can only report the fault.

The optical signal indicator of the optical modem LOS flashes red, indicating that the device has not received the optical signal.

Suggestions: 1. Restart the optical modem;

2. Check whether the bending angle of the line is too large and the phenomenon of extrusion;

3. Check whether the optical fiber interface is loose and plug in the joint;

If the above methods still do not solve the problem, you can call the customer service of the local operator to report the broadband fault.

China Telecom's broadband cat flashes red light, generally because the broadband line is faulty, the optical modem can not receive the optical signal, it is recommended to restart the device first, if it can not be restored, the user can call the telecom customer service for feedback and fault processing, and there are staff members to come to the door within 24 hours after the fault report.

The light signal lights up red, indicating that the optical modem has received no light alarm, and there are the following situations:

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

2. The indoor pigtail connection optical cat connector is loose. Plug the connector in and it can be restored.

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 outdoor optical fiber is broken or the optical port of the operator's equipment room is faulty, you need to find the operator to deal with it.

The flashing red light (LOS light) in the modem signal means that your optical router cannot receive the light signal (under normal circumstances, the LOS light is not on).

At this point, the following is recommended:

To clean the fiber, unplug the fiber head, clean the fiber surface with a cotton swab, and then plug the fiber back in.

If the LOS light is still flashing, check whether the optical fiber is intact and broken.

If the fiber is intact and the light is still flashing. Power off the modem and wait for a few minutes before powering it back on to see if it is normal.

If the fault persists, call the telecom customer service, it may be an external line problem or the optical modem is damaged, and ask them to send someone to repair it.

Optical modem refers to a transceiver device that converts optical ethernet signals into signals of other protocols, and is also known as a single-port optical transceiver, which is a product designed for special user environments.

It utilizes a pair of optical fibers for single E1 or single or single 10Baset point-to-point optical transmission terminal equipment.

For multi-port optical transceivers, they are generally called "optical transceivers", and single-port optical transceivers are generally used on the user side, which work similarly to the baseband modem commonly used for WAN private line (circuit) networking, and are called "optical modem", "optical modem", "optical modem", and "optical modem". Some people often mistake optical fiber transceivers or photoelectric converters for optical modems, in fact, this is a wrong name, optical modem equipment uses large-scale integrated chips, simple circuits, low power consumption, high reliability, with complete alarm status indication and perfect network management function.

First of all, the first situation when the red light is turned on is that the line is broken, and the bright line can be buried in the line, and it is broken.

Then immediately call ** to call the master to come to the door and call late.

The fiber optic line is broken, and I can't pick it up by myself, so I have to have a special machine.

If the light cat at home.

After using it for a long time, the probability of the light cat being bad is also relatively large, so you can call the master to come to the door for testing.

If it's broken, go to the business hall to buy it again, and the warranty period of the light cat is one year.

If you are under construction near your home, it is possible that the main line has been broken by construction.

Only by waiting for professionals to come to repair it, you can go to the neighbor's house to determine whether the area is off the network.

Generally, optical fiber cables cannot be bent, and they are all circled in small circles.

You can bury it along the line** whether there is a bend, and the place where there is a bend can be straightened.

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

The red light of the optical signal of the telecom optical modem is a problem with the external wire, and it cannot be repaired by itself. Call ** for repair, just let the master come to the door.

Telecom Fiber BAI

The cat light light is red, and the fiber optic cat cannot receive the signal dao number, so it cannot go online.

The general reasons are: right.

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 return is unqualified or broken; Answer.

2. The cold connector at the splitter 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.

The light signal of the modem keeps flashing red, and the optical path connected to the optical modem is broken, and the signal light state is off when the optical path is normal.

Inside. Check whether the plugs of the pigtail and optical cat are plugged securely. If there is no problem, check whether the joints of the indoor smooth leather cable and pigtail are disconnected and virtually connected.

If there is no problem in the room, you can contact the outside line maintenance personnel of Telecom. Generally, if the optical path is broken or falsely connected, it is difficult for the user to solve it. Because the splicing of optical fibers requires specialized tools or materials (such as fusion splicers or cold splicers).

In addition, if it is a fault in other parts of the optical path, such as the splitter connector and the optical box, the user cannot deal with it by himself.

The fiber is broken. I can't fix it myself.

Generally, the optical fiber is not light or large.

The optical composite signal LOS light flashes red light system of optical fiber broadband modem.

Generally, if the network is not connected, there is a line failure or the remote computer room is being maintained, this needs to call China Telecom's customer service directly to report the fault, and there will be staff to repair the fault within 48 hours after the fault is successfully reported.

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.
