Fiber optic transceiver light instructions

A fiber optic transceiver is a short-range transceiver for twisted-pair electrical signals. It is also referred to in many places as an optical-to-electrical converter. Fiber-optic transceiver FXLink/Act: Long light indicates that the fiber-optic link is connected correctly; Light indicates that data is transmitted in the fiber. FDX: Lights indicate that the fiber transmits data in full duplex mode. TX100: Lights indicate that the twisted pair transmission rate is 100 Mbps; Lights indicate that the twisted pair transmission rate is 10 Mbps. There are many manufacturers of fiber optic transceivers in the country. The transmission power of 5 km optical fiber transceivers on the market is generally between -20 to -14 db, the receiving sensitivity is -30 db, and the wavelength of 1310 nm is used; the 120 km optical fiber transceiver is launched. The power is more than -5 ~ 0dB.

For the indicator of the fiber transceiver, when the PWR indicator is on, it indicates that the DC5V power supply is working properly. The FX100 indicator light indicates that the optical fiber transmission rate is 100 Mbps. The long blinking TXLink/Act indicator light indicates that the twisted pair link is connected; the light blinks to indicate double There is data in the twisted wire transmission.

Fiber Transceiver LED Fault Description:

1. If the FX indicator of the optical transceiver of the A transceiver is on and the FX indicator of the optical transceiver of the B transceiver is off, the fault is on the A transceiver: One possibility is that: A transceiver (TX) optical transmitter port is broken, Since the optical port (RX) of the B transceiver does not receive the optical signal; another possibility is that this optical fiber link of the A transceiver (TX) optical transmission port has a problem.

2. Twisted Pair (TP) indicator light is off. Please make sure whether the twisted pair connection is wrong or connected incorrectly. Please use continuity tester to test.

3. If the optical transceiver (FX) indicator does not light, make sure that the fiber links are cross-connected and that the fiber jumper is connected in parallel; the other end is a crossover connection.
