Today, Fiber Optic Splice Closure manufacturers share the workings of fiber optics and the manufacturing process of their fiber

At the transmitting end, the information to be transmitted is first converted into an electrical signal and then transmitted to the laser beam through the laser. The intensity of the light changes with the frequency of the electrical signal and is transmitted through the optical fiber. At the receiving end, the detector receives the optical signal. After turning it into an electrical signal, after processing, the original information is restored.

The optical fiber made of glass fiber inside the fiber can transmit optical signals to thousands of kilometers, and combine hundreds of thousands of optical fibers to form a cable with the same cable, which improves the strength of the optical fiber. , and greatly increased the communication capacity.

The speed of light propagation in different materials is different, so when one substance is shot to another, the intersection of the two substances will refract and reflect, and the angle of the refracted light will change with the angle of the incident light. However, when the angle of the incident light reaches or exceeds an angle, the refracted light will disappear and the incident light will be reflected back. This is the total reflection of the light.

The optical signal is transmitted to the endpoint after repeated refraction in the optical fiber. The optical signal is dispersed or attenuated after the primary refraction, and the optical signal needs to be amplified every 50 kilometers.

Then what is the manufacturing process of the optical fiber: First, the embryo body of the optical fiber preform is mainly made of high-purity silica, and is fired into an optical fiber preform at a temperature of 1500 °C.

After 20 hours, the high-purity light bar was successfully fired. The 3m diameter 20cm light rod was suspended into the drawing furnace. The airing tube could be drawn continuously for 7500km within 48 hours. Prevent impurities and dust from falling onto the fiber. The light bar melts into a soft embryo at a high temperature of 2200 degrees Celsius. After passing through a 1-meter long annealing tube, it is gradually cooled into a glass filament with a diameter of 0.1 mm. The wire take-up rotates to drive the fiber and complete the fiber.
