Coherent NuSENSOR graded-index multimode fiber is ideally suited for Raman based distributed temperature sensing. This 0.20 NA fiber features a 50µm core diameter and a 125µm clad diameter with a mid-temperature acrylate coating and is also available with a hermetic carbon coating layer. NuSENSOR multimode fiber is manufactured in-house, and every process step is monitored and controlled providing high bandwidth and low attenuation. As with all Coherent fibers, this multimode fiber provides tight tolerance optical and geometrical specifications measured at the application critical wavelengths. The mid-temperature acrylate coating operates up to 150°C and, with the hermetic carbon coating, is ideal for use in H2 rich environments.
