1. Measured at 1.5 dB below non-saturating reflection peak (-50 dB typical) using 5 ns
pulse width.
2. Measured at ±0.5 dB beyond backscatter (< -50 dB), using 5 ns pulse width,
excluding dispersion.
3. At 1310 nm, non-reflective fiber under test, non-reflective splitter, 13 dB loss, 50 ns
pulse width, measured 0.5 dB beyond backscatter.
4. Backscatter coefficients (based upon ITU-T G.652.D compliant SMF-28e+): -77 dB at
1310 nm, -82 dB at 1550 nm.
5. Using 20 μs pulse. SNR=1 method, 3 minute averaging, 100 km fiber length
