Introduce the new 40GHz RF over fiber Link solution
In the field of microwave communication, the traditional RF over fiber Link solution has always been constrained by two major problems: The expensive coaxial cables and waveguides not only increase the deployment cost, but also firmly bind the signal transmission by distance, and the frequency band coverage and stability are also difficult to meet the requirements of broadband applications. Facing this situation, we are honored to recommend to you – ROFBox series 40GHz External Modulation Broadband Analog RF RF over fiber Link. This is not merely a product; it is an outstanding answer sheet we have submitted to break through physical limitations.
This innovative product adopts the external modulation optical transmission RF over fiber Link solution, supporting lossless conversion of RF signals within the ultra-wideband wide range of 1-40GHz. It replaces traditional metal media with optical fiber links, completely breaking the physical limitations of transmission distance.
Its core advantages lie in: full-band high-fidelity: 1-40GHz wideband coverage, combined with linear-optimized design, ensuring precise reproduction of signal amplitude and phase; Cost-effectiveness leap: Avoid expensive coaxial cables and waveguide assemblies, reducing deployment costs by over 60%; Breakthrough in anti-interference capability: Optical fiber transmission is naturally resistant to electromagnetic interference, and the signal stability in complex environments has been significantly improved.
From signal relay in remote wireless communication to the precise allocation of timing reference signals, and then to the practical application of telemetry systems and delay lines, it can precisely adapt, providing strong support for various broadband microwave scenarios and opening up the possibility boundaries for redefining analog broadband microwave applications.
