The switch quantity optical terminal machine can make the switch quantity signal transmit two-way control on the optical fiber through the optical cable. The all-digital optical transmission channel ensures high-quality signal transmission. There are power indicator light, light signal indicator light and data signal indicator light on the panel, which can intuitively detect the status of power, light signal and data signal. The one-way series switch optical transceiver is a high-performance, high-reliability long-distance switch signal transmission system. Next, let's learn more about the indicator light of the switch meter and the common troubleshooting methods!
1. Description of indicator light of switch optical transceiver:
Power indicator: Green—The indicator light is on when the power is connected normally. It doesn't light up normally.
Light path indicator: Green---The light path is abnormal, and the green light flashes. It does not light up when the light path is normal.
Data indicator: Green---There is data transmission, and the indicator light flashes.
Video indicator: green (together with the light path indicator)-the green light is on when there is video input or output. Nothing is not lit.
Ethernet indicator: The network is normal—the upper left corner of the network port is on. The light in the upper right corner of the normal network port is on. Data transmission is normal, and the light in the upper left corner of the network port flashes.
2. Common troubleshooting of switch optical transceiver:
a) The chassis has no power supply: check whether the electric plug is normal and whether the chassis fuse is normal.
b) All video data is abnormal: check whether the power emitted by the light is normal, and check whether the received light power is within the receiving sensitivity.
c) The video image has irregular horizontal stripes or jumps: the synchronization of the video input is not correct. Check whether the ground level of the system is equal, especially the ground level of the power supply of the optical transceiver and the ground level between the input and output devices. Whether the line connection is good and whether the input signal meets the standard.
d) All the indicators of the optical transceiver are off: check whether the power adapter is working normally, and check whether the optical transceiver module is completely and correctly inserted into the chassis slot
e) The video indicator of the optical transceiver receiver flashes: the receiver does not receive the correct optical signal; check whether the link loss of the optical fiber is normal, the coil diameter of the optical pigtail is too small (the diameter of the optical fiber should not be less than 20 cm), and the pigtail There are impurities on the ceramic interface (can be gently cleaned with alcohol cotton).
f) The video indicator of the optical transceiver transmitter is off: the optical transceiver does not receive the video signal; check whether the video input of the optical transceiver is normal.
g) The video output of the optical transceiver receiver has snowflakes: there are errors in the transmission process, check whether the loss of the optical fiber link is too large, the diameter of the pigtail coil is too small (the diameter of the fiber should not be less than 20 cm), or the ambient temperature of the equipment is too high High, making the transmission unstable.
h) The data of the optical transceiver is abnormal: whether the data protocol is correct (whether RS232 is used to transmit RS422, etc.), whether the data transmission direction is correct (forward, reverse or two-way), whether the wiring is correct (positive or negative data or sending and receiving, etc.), whether the data input correct.
i) It can be combined with the equipment indicator to analyze and solve the equipment failure.
