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.

f. For multimode port, controlled launch conditions allow 50 μm and 62.5 μm multimode fiber testing.

g. Does not include uncertainty due to fiber index.

h. Typical output power is given at 1300 nm for multimode output and 1550 nm for singlemode output.

i. Under improvement to achieve better conditions.
