4 Typical Specification at Reflectance ≤ -50 dB at 30 ns
pulsewidth, and with span
≤ 4 km (typical value).
5 Measured with a standard 62.5
µm guided index
multimode fiber at SNR=1 noise level and with 3 minutes
averaging time, optimize dynamic.
6 Reflectance
≤ -35 dB at 5 ns pulsewidth, and with span
≤ 4 km, optimize resolution.
7 Reflectance
≤ -35 dB at 10 ns pulsewidth, and with span
≤ 4km.
