NOTES
a. All specifications valid at 23 °C ± 2 °C with an FC/PC connector, unless otherwise specified; APC connector for FTB-720G and FTB-730G singlemode model.
b. Typical.
c. Typical dynamic range with longest pulse and three-minute averaging at SNR = 1.
d. Typical dead zone for reflectance below –45 dB, using a 5 ns pulse.
e. Does not include uncertainty due to fiber index.
f. Typical output power is given at 1550 nm.
g. Non-reflective FUT, non-reflective splitter, 13 dB loss, 50 ns pulse, typical value.
