Rayleigh scattering optical fiber
WebApr 3, 2024 · Rayleigh scattering refers to the irregular scattering generated as optical signals transmitting in the fiber. OTDR only measures the scattered light back on the OTDR port. The backscatter signal shows the attenuation degree (loss/distance) of the optical fiber, and will be tracked as a downward curve, illustrating the power of backscatter ... WebFeb 24, 2024 · At 864 nm, close to the 850 nm short-distance communication band, they measured 1.4 dB/km compared to 1.3–2 dB/km for Rayleigh scattering. For the 1064 nm line often used on laser machining, they measured loss of 0.52 dB/km compared to 0.6–0.8 dB/km for Rayleigh scattering in silica. All three fibers have 3 dB bandwidths over 130 nm.
