24 core pull-out box terminal box

Many people have encountered the failure of fiber optic network, but the solution is really different. The 24-core pull-out box terminal box is what we often need to use. Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic, which can be used as a light transmission tool. Optical fiber network is very useful in life. Once a fault occurs, it will cause great trouble. How to troubleshoot common faults and troubleshooting methods of optical fiber network becomes more and more important.

Optical fiber network common faults and troubleshooting methods

First, whether the indicator light of the optical fiber transceiver or optical fiber module and the twisted pair port indicator light are on

If the optical port (FX) indicator of the transceiver is not on, please confirm whether the optical fiber link is cross-linked; one end of the optical fiber jumper is connected in parallel; the other end is connected in cross-connection. If the optical port (FX) indicator of the A transceiver is on, and the optical port (FX) indicator of the B transceiver is not on, the fault is on the A transceiver side: one possibility is: the A transceiver (TX) optical transmission port has been Bad, because the optical port (RX) of the B transceiver cannot receive the optical signal; another possibility is: there is a problem with this optical fiber link of the optical transmission port of the A transceiver (TX) (the optical cable or optical jumper may be broken ).

The twisted pair (TP) indicator is not on, please check whether the twisted pair cable is connected incorrectly or is connected incorrectly. Please use a continuity tester to test; some transceivers have two RJ45 ports: (To HUB) indicates that the connection cable connected to the switch is a straight-through cable; (To Node) indicates that the connection cable connected to the switch is a crossover cable; There is MPR switch on the side: it means that the connection line connected to the switch is a straight-through line; DTE switch: the connection line connected to the switch is a crossover line.

Second, use the optical power meter to detect

The luminous power of the optical fiber transceiver or optical module under normal conditions: multi-mode: between -10db--18db; single-mode 20km: between -8db--15db; single-mode 60km: between -5db--12db ;If the luminous power of the optical fiber transceiver is between: -30db--45db, then it can be judged that there is a problem with the transceiver.

Third, whether the half/full duplex mode is wrong

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

Fourth, whether the optical cable and optical fiber jumper are broken

a. Optical cable on-off detection: use a laser flashlight, sunlight, or illuminator to illuminate one end of the optical cable connector or coupler; see if there is visible light at the other end? If there is visible light, it means that the optical cable is not broken.

b. On-off detection of optical fiber connection: use a laser flashlight, sunlight, etc. to illuminate one end of the optical fiber jumper; see if there is visible light at the other end? If there is visible light, it means that the optical fiber jumper is not broken.

Regarding the failures and solutions of optical fiber networks, we need to make good use of them. 24-core pull-out box terminal box and other related products must be carefully selected.
