Abstract
A method and apparatus for determining a dB loss across an optical fiber splice includes the steps of determining a first maximum detected optical signal when the fiber ends are moved relative to each other in a X direction, determining a second maximum optical signal when the fiber ends are moved relative to each other in a Y direction, determining a third optical signal when the fiber ends are optimally substantially aligned, determining a fourth optical signal when subsequent to the fiber ends actually being secured to each other.
