What are the meanings of the indicator lights of the optical cable splice box?

1. If the optical port (FX) indicator of the optical cable splice box is not on, please determine whether the optical fiber link is cross-linked. One end of the fiber jumper is connected in a parallel way; the other end is connected in a cross way.

2. 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: A transceiver (TX) optical transmission The port is broken, because the optical port (RX) of the B transceiver cannot receive the optical signal; another possibility is: there is a problem with the optical fiber link of the optical transmission port of the A transceiver (TX), such as an optical cable or optical jumper Maybe broken.

3. The twisted pair (TP) indicator light is not on, please determine whether the twisted pair connection is wrong or the connection is wrong. Please use a continuity tester to detect the following situations. The twisted pair indicator of some optical cable splice boxes will not be on until the optical fiber link is connected.

4. Some junction boxes have two RJ45 ports: (ToHUB) indicates that the connection cable connected to the switch is a straight-through cable; (ToNode) indicates that the connection cable connected to the switch is a crossover cable.

5. There is an MPR switch on the side of some connector boxes: it indicates that the connection line connecting the switch is a straight line method; DTE switch: the connection line connecting the switch is a cross line method.
