3. Low loss: Compared with traditional copper wire communication, optical fiber communication has less signal attenuation and a longer transmission distance. This enables optical fiber communication to maintain good signal quality over long distances.
4. Anti-interference: Optical fiber communication has a high resistance to electromagnetic interference and can stably transmit data in a complex electromagnetic environment.

V. Disadvantages of optical fiber communication

1. High cost: The construction and maintenance cost of optical fiber communication is relatively high, mainly including the cost of optical fiber materials, equipment, and manpower. This limits the application of optical fiber communication in some developing countries and regions.
2. Difficult to troubleshoot faults: In optical fiber communication systems, once a fault occurs, it often requires professionals to troubleshoot and repair. Due to the particularity of optical fibers, fault points are often difficult to locate, increasing the difficulty of fault troubleshooting.
3. Affected by the environment: Optical fiber communication has higher requirements for the environment. Especially in extreme environmental conditions, such as areas with high temperatures, low temperatures, and large humidity changes, the performance of optical fiber communication may be affected.
4. Power supply dependence: Optical fiber communication equipment requires a stable power supply. Once there is a power outage or unstable power supply, the communication system will not operate normally.

VI. Solving the limitations of optical fiber communication

1. Reduce costs: To solve the high cost problem of optical fiber communication, technological innovation and large-scale production can be used to reduce the cost of optical fiber materials and equipment. At the same time, provide training and technical support to reduce manpower costs.
2. Improve fault troubleshooting ability: For the problem that optical fiber communication faults are difficult to troubleshoot, advanced fault detection technologies and equipment can be used to improve the accuracy of fault location. In addition, establish a complete fault troubleshooting and maintenance team, strengthen personnel training, and improve the efficiency of fault troubleshooting.
3. Resist environmental interference: To solve the problem that optical fiber communication is affected by the environment, special optical fiber materials and technologies can be used to improve the anti-interference ability of optical fibers. At the same time, strengthen the maintenance and management of optical fiber communication systems, regularly inspect and clean optical fiber equipment to ensure its normal operation.
4. Backup power supply and power supply guarantee: To solve the problem of power supply dependence of optical fiber communication, a backup power supply such as a UPS (uninterruptible power supply) system can be set up to ensure that the optical fiber communication system can continue to operate in the event of a power outage or unstable power supply.

VII. Operation steps of optical fiber communication technology

1. Selection of light source: Select a suitable light source, such as a laser or LED.
2. Optical signal modulation: Modulate the optical signal through a modulator to carry information.
3. Optical signal amplification: Use an optical fiber amplifier to amplify the optical signal to compensate for signal attenuation during transmission.
4. Optical fiber transmission: Transmit the modulated and amplified optical signal through an optical fiber.
5. Photoelectric conversion: At the target location, convert the optical signal into an electrical signal through a photoelectric converter.
6. Signal processing: Perform signal demodulation, amplification, and other processing on the electrical signal.
7. Signal reception: Use a receiver to receive and decode the electrical signal to obtain the original information.
