∗1 At 25°C, pulse width: 1 µs
∗2 For GI fiber (core diameter: 62.5 µm ±3.0 nm, NA: 0.275 ±0.015, transmission loss: ≤3.2/0.9 dB/km
(wavelength: 0.85/1.3 µm). At measurement of 50/125 µm GI fiber, the dynamic range drops by about
3.0 dB.
∗3 At 25°C, pulse width: SM 20 µs, GI 100 ns (0.85 µm), 1 µs (1.3 µm)
∗4 Pulse width: 10 ns, return loss: SM 40 dB, GI 30 dB, deviation: ±0.1 dB (Refer to the figure right.)
∗5 Pulse width: 10 ns (Refer to the figure right.)
∗6 Either value is automatically selected in each mode, depending on the distance range.
∗7 Automatic measurement is a supporting function which enables to operate easier, it doesn’t assure
results. As there is a case of miss detection, please check a waveform data, either.
∗8 At quick mode
∗9 Compared value with internal wavelength data at chromatic dispersion measurement
∗10 Measured with 25 km of 1.3 µm zero-dispersion fiber (ITU-T G.652) at 1550 nm.
Not an error from absolute value but repeatability of measured results. Contact Anritsu Corporation in
case of measuring ITU-T G.655 fiber.
∗11 At back light low brightness, measurement not executed.
∗12 Dropped on the floor of plywood thickness 5 cm fixed by concrete. Not applicable to the MW9076D1.
