Power-over-Fiber with Simultaneous Transmission of Optical Carrier for a High Frequency Analog Signal over Standard Single-Mode Fiber

Efficient simultaneous transmission of light with a power more than 2 W at wavelength 976 nm and an optical carrier for transmitting high-frequency analog signal 1550 over distance 1 km standard single-mode fiber was experimentally demonstrated. Electrical up to 350 mW (5 V, 70 mA) obtained from multi-junction silicon photocell, resulting in the efficiency about 70% photocell 25%. The did not affect high frequency signal. Key broadband characteristics such as noise figure (NF < 25 dB) spurious-free dynamic range (SFDR3 > 117 dB/Hz2/3) were achieved close fundamental shot limit. This approach is promising powering remote antenna unit fronthaul architecture.
