NOTES
a. All specifications valid at 23 °C ± 2 °C with an FC/PC connector, unless otherwise specified;
APC connector for FTB-720 singlemode model.
b. Typical.
c. Typical dynamic range with longest pulse and three-minute averaging at SNR = 1.
d. Multimode dynamic range is specified for 62.5 μm fiber; a 3 dB reduction is seen when testing
50 μm fiber.
e. Typical dead zone for multimode reflectance below –35 dB and singlemode reflectance below
–45 dB, using a 5 ns pulse.
