What Is a Fiber-Optic Repeater?

Optical fiber repeater is a repeater that uses optical fiber for signal transmission. It uses the characteristics of small optical fiber transmission loss, convenient wiring, and suitable for long-distance transmission. It can solve villages, tourist areas, highways, etc. that cannot receive base station signals. Signal coverage in large and very large buildings is used for occasions such as buildings (groups) and communities with large requirements in high-rise areas.

Fiber-optic repeater uses the optical fiber for signal transmission

Optical fiber repeater is mainly composed of optical near-end machine, optical fiber, and optical remote machine (covering unit). Optical near-end and optical remote-end both include

Optical fiber repeater construction problems in highway tunnel coverage: Due to the complicated terrain of the tunnel, the difficulty in obtaining the source, the narrow coverage area, and the large signal fluctuation loss, etc., it is necessary to carry out survey and design according to the actual environment and mobile networking Plan; Based on the characteristics of highway tunnels, fiber optic repeaters are well-used in highway tunnels due to their smart design and construction, good coverage, and stable work.

It can be explored from the following aspects:

1 Transmission distance request The transmission distance of the fiber-optic repeater can be up to 15 kilometers, so for general narrow tunnels, as long as the transmission distance is not exceeded, the fiber-optic repeater can be used for coverage.

2 Selection of information source The selection of information source is directly related to the overall coverage effect. Therefore, it is necessary to ensure that the Tan Yue base station has redundant traffic capacity, which can burden the traffic in the coverage area of the fiber repeater. If no source is available near the tunnel entrance or the tunnel is longer, a coupler is used to couple the signal from the base station to the near-end unit. The near-end unit converts the RF signal into an optical signal and sends the optical signal to the remote unit through the optical cable. The machine converts the optical signal into a radio frequency signal and amplifies the signal to feed it to the antenna. Determine the number of remote units based on the coverage interval and the effect of the near-end units dragging the remote units on the base station noise.
