AcoustiSens® Wideband Vibration Sensor Fiber – Improved OSNR for Great ASNR

AcoustiSens Wideband Single-Mode Optical Fiber, the newest addition to the OFS LineaSens® family, is a vibration sensing fiber with optimal performance for Distributed Acoustic Sensing (DAS) systems. Using a waveguide design based on the ITU-T G.657.A1 telecom-grade single-mode standard, AcoustiSens Wideband Optical Fibers significantly increase Rayleigh backscatter while maintaining low attenuation to improve Optical Signal to Noise Ratio (OSNR). Furthermore, the AcoustiSens Wideband Optical Fibers provide bend-insensitivity and expand the operating wavelength band (1536 – 1556 nm) ensuring interoperability with all known DAS interrogators. AcoustiSens Wideband is intended for use in cables designed as sensing components in DAS systems. Without the need for changes in interrogation equipment or complex optical amplification schemes AcoustiSens Wideband is a drop-in fiber replacement that provides greatly improved sensing performance with OSNR orders of magnitude better than telecom-standard fibers. This translates into significantly improved ASNR in DAS systems. Due to its waveguide design, AcoustiSens fibers are also bend-insensitive and splice compatible with G.657.A1 and G.652.D optical fibers, assuring smooth integration with commonly deployed sensing solutions.

Typical Examples
