Fiber as a temperature sensor with portable Correlation-OTDR as interrogator
Florian Azendorf, Annika Dochhan, Florian Spinty +3
In this paper, we report on the integration of a Correlation-OTDR into a portable unit (30 cm x 30 cm), based on a multi-processor system on chip (MPSoC) and a small formfactor plu…
Latency Measurement of 100 km Fiber Using Correlation-OTDR
Florian Azendorf, Annika Dochhan, Bernhard Schmauss +1
By means of C-OTDR (Correlation - Optical Time Domain Reflectometry), we measured the latency of100 km fiber with an accuracy of a few picoseconds. Based on iterating 49 measuremen…
Group Delay Measurements of Multicore Fibers with Correlation Optical Time Domain Reflectometry
Florian Azendorf, Annika Dochhan, Florian Spinty +3
Several multi-core fibers (MCF) were characterized using Correlation Optical Time Domain Reflectometry (C-OTDR) in terms of propagation delay and polarization mode dispersion (PMD)…
Characterization of Multi-Core Fiber Group Delay with Correlation OTDR and Modulation Phase Shift Methods
Florian Azendorf, Annika Dochhan, Krzysztof Wilczyński +8
Using a Correlation-OTDR and a modulation phase shift method we characterized four multi-core fibers. The results show that the differential delay depends on the position of the co…
Improvement of accuracy for measurement of 100-km fibre latency with Correlation OTDR
Florian Azendorf, Annika Dochhan, Jim Zou +2
We measured the latency of a 100 km fibre link using a Correlation OTDR. Improvements over previous results were achieved by increasing the probe signal rate to 10 Gbit/s, using di…
56 Gb/s DMT Transmission with VCSELs in 1.5 um Wavelength Range over up to 12 km for DWDM Intra-Data Center Connects
Annika Dochhan, Nicklas Eiselt, Robert Hohenleitner +7
We demonstrate up to 12 km, 56 Gb/s DMT transmission using high-speed VCSELs in the 1.5 um wavelength range for future 400Gb/s intra-data center connects, enabled by vestigial side…
