AI Technical Summary
The lasers in the remote electro-optic conversion units of existing ROF transmission systems have high power consumption and complexity, making them difficult to adapt to harsh environments and affecting the system's scalability and stability.
Multi-wavelength lasers are concentrated in the near-end local oscillator light distribution unit and connected to the far-end electro-optical conversion unit via optical fiber. The near-end detection and control unit enables precise control of the laser output wavelength and optical signal amplitude, simplifying the structure of the far-end electro-optical conversion unit.
The power consumption and complexity of the remote electro-optical conversion unit are reduced, making the system suitable for harsh environments and improving the system's stability and applicability.
