Who pays for the broken fiber at home?

The installation of network cable and optical cable is very important. It's hard to imagine what life would be like in the future if there was no internet at home. However, in some cases, the optical fiber may break and need to be repaired immediately. Therefore, family owners should first look at who pays for the broken optical fiber, how to troubleshoot the optical fiber network, master effective troubleshooting methods, and achieve the maintenance effect faster.

Who pays for the broken fiber at home?

The optical fiber at home is broken, and the property is responsible for maintenance. The maintenance responsibility of all operators is to interface to the LAN port of fttp or the optical cat entering the building. As long as the Ethernet port test of the optical cat is normal, it means that the operator's network is normal. If there is something wrong with the comprehensive wiring of the building, you can find a property management company to repair it. These network cables were laid during the construction of the building and have nothing to do with the operators.

How to clear the optical fiber network fault?

1. Whether the indicator light of optical fiber transceiver or optical fiber module and the indicator light of twisted pair port are on.

If the optical port (FX) indicator of the transceiver is not lit, please determine whether the optical fiber link is cross-connected; One end of the optical fiber jumper is connected in parallel; The other end is cross-connected. If the optical port (FX) indicator light of transceiver A is on, the optical port (FX) indicator light of transceiver B is off, and the fault is at the transceiver A end: one possibility is that the optical transmission port of transceiver A (TX) is broken because the optical port (RX) of transceiver B cannot receive optical signals; Another possibility is that the optical transmission port of a transceiver (TX) has a problem with this optical fiber link (the optical cable or optical jumper may be broken).

Second, the use of optical power meter instrument detection

Under normal circumstances, the optical power of optical fiber transceiver or optical module: multimode: between-10 dB- 18 dB; Single mode 20km:-8dB-15dB; Single mode 60km: between -5dB- 12dB; If the optical power of the optical fiber transceiver is between -30dB and -45dB, it can be judged that there is something wrong with this transceiver.

3. Is there something wrong with the half-duplex/full-duplex mode?

Some transceivers have FDX switches on the side: full duplex and HDX switches: half duplex.

4. Is the optical cable and optical fiber jumper broken?

On-off detection of optical cable: illuminate one end of optical cable connector or coupler with laser flashlight, sunlight and luminous body; See if there is visible light at the other end. If there is visible light, the optical cable is not broken. On-off detection of optical fiber connection: irradiate one end of optical fiber jumper with laser flashlight and sunlight to see if there is visible light at the other end. If there is visible light, the optical fiber jumper is not broken.

The above introduction is who pays for the broken optical fiber and how to clean up the optical fiber network fault. Nowadays, optical fiber is the type of choice for many families, mainly because it is faster, more stable and not particularly expensive, and most of them are acceptable. However, it is not excluded that there will be some maintenance problems during the use of the lamp, so you should know how to clean up all kinds of faults.
