All-plastic optical fiber radio broadcast communication system and implementation method thereof

Abstract

The invention discloses an all-plastic optical fiber radio broadcast communication system and an implementation method thereof. The system comprises a central route station and one or more remote antenna units, wherein a plastic passive optical splitter is arranged between the central route station and a remote antenna, the central route station is connected with the passive optical splitter through a plastic optical fiber, and one or more remote antenna units are connected with the plastic passive optical splitter through the plastic optical fiber. According to the invention, by adopting a vertical-cavity surface-emitting laser in a red light waveband, and utilizing amplification effect of a light transmission window for the plastic optical fiber and a plastic passive light split machine, and a snow slide photoelectric receiver, vices of large loss and large dispersion of a medium are overcome, the short-distance, high-quality and safe radio frequency signal transmission is realized, and compatibility of different communication and broadcast standards is ensured by utilizing transparence of an optical fiber about a protocol. In addition, according to the invention, a system framework is greatly simplified, the integrated cost of a product is reduced, and the utilization efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of wireless broadcast communication, in particular to a low-cost all-plastic optical fiber wireless broadcast communication system and its implementation method. Background technique [0002] With social development and technological progress, the public has increasingly urgent and strong demands for information broadcasting and interaction, hoping to communicate and share anytime, anywhere. Therefore, the next-generation wireless broadcast communication technology will be forced to adapt to the rapidly expanding data traffic and provide ubiquitous high-quality access services. At present, it is difficult for broadcast / telecom operators to keep up with this trend and complete wireless coverage in remote or complex environments at a relatively low cost. With the advancement of technology, the combination of low-cost optical fiber transmission and high-cost wireless transmission will become a new trend. As a...

Problems solved by technology

And the setting of the optical amplifier increases the complexity of the product, greatly improves the energy consumption, and also reduces the overall life of the system

In addition, the splicing and laying of SMF-28 standard optical fibers require professional equipment and technical personnel, which is very inconvenient

The optical transmission band used is invisible light. When the laser emits high power, it will cause permanent damage to the retina.

The optical fiber itself is also potentially dangerous. It is easy to penetrate the skin and enter the human body, and it is difficult to distinguish and take it out. It is necessary to take corresponding protective measures during operation.

Therefore, as a commercial solution, a dedicated team is required for construction and maintenance. It is almost impossible for users to troubleshoot by themselves, and the overall cost of system ownership and operation and maintenance is relatively high.
