There is no absolute reason, and when people who are healthy are sick again, not to mention products? When Shenzhen Weiyueshida telephone optical transceiver is shipped from the factory, it is ensured that it has been debugged without any faults. In the process of application, there may be some situations. The following are common problems and solutions for telephone optical transceivers.
Telephone Optical PWR green light and <br> <br> A: The power failure. Please check if the power supply is normal. Do not reverse the -48V power cable.
Telephone Optical G reported total red light <br> <br> A: The following situations resolved.
1. If the alarm light is on, the local alarm is displayed. If the alarm is blinking, there is an alarm on the remote end.
2. If the other alarm lights are completely off, the latching button has been cleared, but the G lamp still flashes or lights up. In the E1 received signal, there is an HDB3 encoding violation alarm. Generally, the E1 line is too long and the interference is too large. The signal loss has exceeded -6 dB. The error level when using this E1 line can be measured.
Telephone Optical red light optical port OS <br> <br> A: optical interface receiving signal loss. Check whether the fiber input RX is connected and reversed. The available optical power meter can detect the received optical power and should be greater than the optical port receiver sensitivity parameter.
Telephone Optical optical port <br> <br> OF A red light: a light reception signal port LOF. An optical signal has been received, but the optical power may be at a sensitivity threshold. Detect the received optical power and confirm whether the remote optical transmit interface TX is connected properly.
Telephone Optical optical port E-3 A red light <br> <br>: optical signal receiving opening is greater than 10-3 bit error occurs. Check whether the optical port is received properly and detect the received optical power.
Telephone Optical optical port E-6 <br> <br> A yellow light: a light receiving port 10-6 is greater than the error signal occurs. After the device is powered on, an E-6 alarm may occur. It is normal. After about 10 seconds, the E-6 indicator turns off. If E-6 alarms occur during operation, check whether the optical port is received properly and detect the received optical power.
E1 PDH tributary phone OS is missing the red light <br> <br> A: E1 tributary of the received signal loss alarm. No HDB3 encoded input. Check whether the E1 interface is properly connected. Check whether the 75 ohm cable is reversed and whether the 120 cable sequence is correct. For the unused E1 tributaries, the OS alarms that occur may be masked by the false alarms after all the devices are tuned.
Telephone Optical official phone went dead <br> <br> A: bad phone, or the phone line is broken. Check the phone line and replace the phone.
The telephone optical transceiver shielding pseudo alarm button has been placed in the MASK masked state, but the E1 branch alarm has not been used yet.
A: After the device is powered off, the power is restored, making the shielding function ineffective. The masking function can be disabled and then enabled, that is, the button is pushed out and pressed again.
The above is the situation and solutions for Shenzhen Wei'ao Vision Optical Telephone Optical Co., Ltd. in the application. If it is encountered in the construction process, it will be solved according to the above method. If there are still problems that cannot be solved, you can call Shenzhen Wei'ao Up to the service telephone;

Stainless Steel Weld Bolts Studs are created to DIN 32501 standard and are designed for welding to thin gauge sheet metal. They are also known as Threaded Capacitor Discharge Studs.
Hosting cold-formed pips at the end of the studs, they are applied using a welding gun, with the ignition tips at the base of the stud creating an arc which melts the base of the stud and the fixing surface, creating an instant fusion weld.
