NOTES
a. Typical.
b. Typical dynamic range with longest pulse and three-minute
averaging at SNR = 1.
c. Multimode dynamic range is specified for 62.5 μm fiber; a 3 dB
reduction is seen when testing 50 μm fiber.
d. Typical dead zone for multimode reflectance below –35 dB and
singlemode reflectance below –45 dB, using a 5 ns pulse.
e. For multimode port, controlled launch conditions allow 50 μm
and 62.5 μm multimode fiber testing.
f. Does not include uncertainty due to fiber index.
g. Typical output power is given at 1300 nm for multimode output
and 1550 nm for singlemode output.
