Limited phase-space attenuation measurements of low-loss optical waveguides
Abstract:
Attenuation and near-and far-field measurements, which were made with different launch spot sizes and numerical apertures on sub-1.0-dB/km optical waveguides, have shown that an equilibrium mode distribution is not established in the 1.1-km length. It was experimentally found that the source launch conditions could be described by an effective mode volume (EMV) that was found to be correlated with the measured attenuation rate. By using an EMV transfer model, the insertion loss of a 3.3-km concatenated section was predicted within 0.21 dB of that measured for a variety of launch conditions.

Attenuation
When constant series resistance and shunt conductance are present, voltage and current equations are modified. The propagation constant indicates that voltage and current waves consist of both forward and backward traveling components. These waves attenuate as they propagate, with the attenuation factor related to the resistance and conductance. In a...
Boundary Conditions: Lossless Lines
At the receiving end, the boundary condition states that the voltage equals the product of the receiving-end impedance and current. This relationship is expressed as a function of the incident and...
