  • Abstract
    In fibre attenuation measurements by the `cut-back¿ method, the necessity for a homogeneous detector is implicit. We have found a commonly used germanium detector to be significantly inhomogeneous, leading to an estimated attenuation discrepancy of 0.02 dB at best and 0.4 dB at worst. In the letter, we outline a method for reducing this discrepancy to levels of less than 0.004 dB.
