Flexible, Easy handling on site and tensile strength up to 40 kg-f
Length marks for easy identification of installation

The FN-EBSM-01 is a strain and temperature sensing cable designed for distributed fiber optics sensing. It offers excellent, linear responses tomechanical and/or thermal loads, providing accurate strain or temperature measurements. By incorporating one singlemode and one multimodeoptical fibers in the center of the cable, it allows one not only to obtain very accurate strain and temperature measurements, but also to perform atempearuture compensation. Its embossed surface enables very good adhesion to measured object, preventing any slippage. In addition, two strength
members provide a tensile strength up to 40 kg force.
The resin sheath of FN-EBSM-01 is flexible and easy to bend. Optical fibers can be easily extracted for splicing.
The length marks on cable make the installation and position identification easy and efficient.

The FN-EBSM-01 is calibrated with state-of-the-art NEUBRESCOPE's Brillouin and Rayleighsensing technology. It has excellent characteristics that supports not only Brillouinscattering measurement (BOTDR, BOTDA method) but also high-precision Rayleighscattering measurement (TW-COTDR method).
The Figure right presents measurements resultsin both fibers subject to 40 hours of thermal load
test (20-80-20C, with 10C step). In total,
640,000+ data points were available forhysteresis effects analysis.
The results clearly demonstrate that the cablemaintained its structure and reinforcing
members maintained both elongation anddeformation characteristics during temperature
increase and decrease.
