Technical Field

[0001] This invention relates to the field of optical communication technology, specifically to an anti-overload optical fiber delay system and device. Background Technology

[0002] Optical communication technology has become an important component of modern information and communication technology. However, with the rapid development of optical communication technology, some shortcomings of traditional fiber optic delay lines, such as lack of overload resistance and poor scalability, have become increasingly prominent.

[0003] In practical optical communication systems, due to the different operating frequencies of the transmitting and receiving ends, and the need for various operations such as modulation / demodulation, processing, and adjustment, overload-induced bit errors and signal attenuation may occur during data transmission. Under these circumstances, traditional fiber optic delay lines may experience photon drift or waveguide failure, leading to system performance degradation or malfunction. Therefore, an overload-resistant fiber optic delay system and device are proposed to address the aforementioned problems. Summary of the Invention

[0017] Compared with the prior art, the present invention provides an anti-overload fiber optic delay system and device, which has the following beneficial effects:

[0018] This invention relates to an anti-overload fiber delay system and device. The fiber optic component described herein uses carbon film fiber, a novel optical material prepared based on fiber optic technology. Its main characteristic is the coating of a carbon film onto the fiber core, with the thickness and quality of the carbon film controlled through various methods. This optimizes and improves the optical performance of the fiber and achieves an impact resistance of ≥10WG. Carbon film fiber has the following significant characteristics:

[0019] High-temperature stability: Carbon film materials have strong high-temperature stability and maintain good optical performance even in high-temperature environments, thus greatly enhancing the service life and reliability of optical fibers.

[0020] High radiation resistance: Due to the excellent radiation resistance of carbon film, carbon film optical fiber can work normally in environments with high radiation field strength, avoiding the influence of radiation on optical transmission, making it more widely used in fields such as nuclear industry.

[0021] High nanoscale characteristics: Since the microstructure of carbon film is equivalent to the interlacing of layers of nanostructures, carbon film optical fiber has high nanoscale characteristics and can be used in fields such as nano-measurement, nanodynamics, and optical nanofabrication.

[0022] High transmittance: Carbon film optical fiber has high transmittance in the visible and near-infrared light bands, and the transmittance performance of the optical fiber can be controlled by adjusting the material and thickness of the carbon film covering it. Therefore, carbon film optical fiber can be used in many fields such as ultra-high-speed communication systems, quantum communication and biomedicine.

[0023] High end-face flatness: The carbon film fiber end face undergoes high-quality processing using various optical processing methods, achieving very high flatness and low fluctuation of the fiber end face, which greatly improves the quality and efficiency of fiber optic transmission.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 An overload-resistant fiber delay system includes a laser, a splitter, a detector, an amplifier power divider, a radio frequency output, and a fiber optic assembly. The laser generates a light source and converts an electrical signal into an optical signal. The splitter divides one optical path into two optical paths. The detector detects the laser beam and converts the optical signal into an electrical signal. The amplifier power divider selects one signal link, amplifies the power, and outputs it to an external radio frequency SMA. The fiber optic assembly uses carbon film fiber.

[0031] Please see Figure 2-4 An overload-resistant fiber delay device includes a laser 1, a power board 2, an RF emitting element 3, an RF emitting element 4, a housing 1 5, a housing 2 6, an amplifier power divider 7, a detector 8, and an fiber optic assembly 9. The housing 15 has a top layer for accommodating the laser 1 and the power board 2, and the housing 26 has an RF layer for accommodating the detector 8, the amplifier power divider 7, and the fiber optic assembly 9.

[0032] In this anti-overload fiber delay system and device, the radio frequency signal is input to the laser 1 through the radio frequency connector, which converts the electrical signal into an optical signal. The output optical signal of the laser 1 is split into two optical signals by a splitter. The two optical signals are respectively entered into optical fibers of different lengths for delay, and then transmitted to two photodetectors 8. The detectors 8 convert the optical signal into an electrical signal, and then the two electrical signals are amplified by the amplifier power divider 7. After the two electrical signals enter the amplifier power divider 7, the amplifier power divider 7 selects one signal for output. The amplifier power divider 7 uses a microwave switch for link selection.
