The optical fiber fusion splicer for communication consists of a high-voltage source, a discharge electrode, an optical fiber adjustment device, a controller, a microscope and a heater (heat furnace).
1. High-voltage source: One is a high-voltage power supply that increases DC and AC power supply to a high voltage of 3 to 4 kV and a current of about 20mA.
The other is upgraded to 20KHz or 40KHz high-frequency power supply.
2. Discharge electrodes: A pair of electrodes with 30-degree cone-shaped tips are processed from gold tungsten rods and installed on the electrode frame. The distance between the electrode tips is generally 0.7mm.
When the high-voltage source is turned on, an arc is generated, which fuses the optical fiber at the center of the arc.
The service life of the electrode is generally 1,000 times.
Continuing to use the electrode if it is excessively consumed will increase the connection loss.
