“…It could also be due to different heat treatments of the two samples of glass since these are known to cause quite large changes in the loss coefficients. Results obtained for F2 at 633 nm with a rather simpler apparatus [12] using a helium/neon laser give 560 dB/km as compared with 390 dB/km from fig. 5a.…”

“…In this work we improve and automate a well-known characterization approach for the study of locally out-scattered light [12,13] to provide accurate length-resolved measurements of the out-scattered fraction of light from a fiber under test (FUT). We name this technique (longitudinally resolved) Optical Side Scattering Radiometry (OSSR).…”

Current optical reflectometric techniques used to characterize optical fibers have to trade-off longitudinal range with spatial resolution and therefore struggle to provide simultaneously wide dynamic range (>20dB) and high resolution (<10cm). In this work, we develop and present a technique we refer to as Optical Side Scattering Radiometry (OSSR) capable of resolving discrete and distributed scattering properties of fibers along their length with up to 60dB dynamic range and 5cm spatial resolution. Our setup is first validated on a standard single mode telecoms fiber. Then we apply it to a record-length 11km hollow core photonic band-gap fiber (HC-PBGF) the characterization requirements of which lie far beyond the capability of standard optical reflectometric instruments. We next demonstrate use of the technique to investigate and explain the unusually high loss observed in another HC-PBGF and finally demonstrate its flexibility by measuring a HC-PBGF operating at a wavelength of 2µm. In all of these examples, good agreement between the OSSR measurements and other well-established (but more limited) characterization methods, i.e. cutback loss and OTDR, was obtained.
