Critical sites such as tunnels and mines often suffer from limited communication. This challenge is further exacerbated during emergencies, such as earthquakes, when ordinary communication networks may be down. To address this problem, RFOptic provides RF over Fiber (RFoF) and GPS over fiber solutions for mines, tunnels, and underground transportation systems.
RFOptic offers RF over Fiber links operating at 2.5GHz, 4GHz, and 6GHz, along with GPS, specifically designed for use in mines and tunnels where wireless solutions are restricted due to line-of-sight limitations. These RFoF solutions ensure reliable communication between underground locations and surface management, enhancing safety and coordination during operations.
Additionally, RFOptic’s systems provide high stability and low signal loss, critical for maintaining clear communication in challenging underground environments. The technology allows for accurate timing and RF communication signals to and from above ground into mines, tunnels, and subway systems, ensuring that personnel can stay connected and receive vital information during critical situations. This capability not only improves operational efficiency but also significantly enhances safety protocols, providing peace of mind for workers in hazardous conditions.
Why is there a demand for RF over Fiber in emergency communication for underground sites?
That's because RFoF technology is critical for communication in mines, tunnels, and emergency services, carrying two-way radio, GPS, and public safety signals (like TETRA or cellular) deep underground by converting RF into light pulses over fiber.
Why is RFoF technology critical for emergency communication in mines and tunnels?
It enables accurate timing and RF communication to and from above ground into mines, tunnels, and subway systems, keeping personnel connected and informed during critical situations. RFOptic's solution is already deployed at several such sites.
Why should I choose RFOptic for communication in an underground site?
RFOptic's systems provide high stability and low signal loss, critical for maintaining clear communication in challenging underground environments. Furthermore, the Tx and Rx units include LNAs and variable attenuators that enable the customer to adjust the Noise Figure, Input P1dB, and IP3 with wide dynamic range values.
How are GPS signals provided in an underground tunnel or mine over fiber?
Typically, a GPS/GNSS system uses an outdoor antenna to receive the satellite signal, then distributes a replica of the timing/reference signal over fiber into the tunnel or mine.
What are the benefits of RFOptic's solution for mines, tunnels, and underground sites?
RFOptic's solution provides improved communication and coverage, enhanced safety, lower maintenance costs, and increased operational efficiency and scalability. These next-generation RFoF modules feature better linearity, excellent gain flatness, and link gain control. Key features also include a Noise Figure down to 10 dB, an internal microcontroller for RF and Optical control and end-to-end diagnostics enabled by software.
