CLASS 1 LASER PRODUCT
1 Calibration is performed internally using a NIST-traceable HCN gas cell
2 Temperature and strain accuracies from spectral shift of Rayleigh scatter are 0.15 °C and 1.25 µStrain, calculated
using the default conversion coefficients 1 GHz = 0.8 °C = 6.58 µStrain [Othonos and K Kalli, Fiber Bragg Gratings
(Artech House, Boston, 1999)].
