Phase-sensitive OTDR probe pulse shapes robust against modulation-instability fading

Typical phase-sensitive optical time-domain reflectometry (ϕOTDR) schemes rely on the use of coherent rectangular-shaped probe pulses. In these systems, there is a trade-off between the signal-to-noise ratio (SNR), spatial resolution, and operating range of the ϕOTDR system. To increase any of these...

In these systems, there is a trade-off between the signal-to-noise ratio (SNR), spatial resolution, and operating range of the ϕOTDR system. To increase any of these parameters, an increase in the pulse peak power is usually indispensable. However, as it is well known, there is a limit in the allowable increase in probe power due to the onset of undesired nonlinear effects such as modulation instability. In this Letter, we perform an analysis of the effect of the probe pulse shape on the visibility fading due to modulation instability. In particular, four different temporal profiles are chosen: rectangular, Gaussian, triangular, and super-Gaussian (order 2). Our numerical and experimental analyses reveal that the use of triangular or Gaussian-like pulses can significantly inhibit the visibility fading issues. As such, an increase in the range up to twofold for the same pulse energy (i.e., SNR) and nominal spatial resolution can be achieved, as compared with the results obtained when using rectangular pulses. This is due to a more robust behavior of the Gaussian and triangular pulses against the Fermi–Pasta–Ulam recurrence occurring in modulation instability.Comunidad de MadridMinisterio de Economía y CompetitividadEuropean CommissionOptical Society of America20162016-12-12journal articlehttp://purl.org/coar/resource_type/c_6501NAhttp://purl.org/coar/version/c_be7fb7dd8ff6fe43info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10017/28157https://dx.doi.org/10.1364/OL.41.005756reponame:e_Buah Biblioteca Digital Universidad de Alcaláinstname:Universidad de Alcalá (UAH)InglésengEuropean Commission http://dx.doi.org/10.13039/501100000780 Seventh Framework Programme 307441 Ubiquitous optical FIbre NErvesEuropean Commission http://dx.doi.org/10.13039/501100000780 Seventh Framework Programme 608099 Allied Initiative for Training and Education in Coherent Optical NetworksMinisterio de Economía y Competitividad http://dx.doi.org/10.13039/501100003329 Not available TEC2013-45265-R DETECCION TEMPRANA DE AMENAZAS PARA INFRAESTRUCTURAS CRITICAS USANDO SISTEMAS DISTRIBUIDOS DE FIBRA OPTICAMinisterio de Economía y Competitividad http://dx.doi.org/10.13039/501100003329 Not available TEC2015-71127-C2-2-R REDUCCION DE LOS EFECTOS DE RUIDO EN SISTEMAS DE FIBRA OPTICA NO LINEALESEuropean Commission http://dx.doi.org/10.13039/501100000780 Horizon 2020 Framework Programme 722509 Fibre Nervous Sensing SystemsComunidad de Madrid http://dx.doi.org/10.13039/100012818 Not available S2009%2FMIT2790 SENSORES E INSTRUMENTACION EN TECNOLOGIAS FOTONICASopen accesshttp://purl.org/coar/access_right/c_abf2Atribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccessoai:ebuah.uah.es:10017/281572026-06-18T11:13:07Z

In these systems, there is a trade-off between the signal-to-noise ratio (SNR), spatial resolution, and operating range of the ϕOTDR system. To increase any of these parameters, an increase in the pulse peak power is usually indispensable. However, as it is well known, there is a limit in the allowable increase in probe power due to the onset of undesired nonlinear effects such as modulation instability.

As such, an increase in the range up to twofold for the same pulse energy (i.e., SNR) and nominal spatial resolution can be achieved, as compared with the results obtained when using rectangular pulses. This is due to a more robust behavior of the Gaussian and triangular pulses against the Fermi–Pasta–Ulam recurrence occurring in modulation instability.
