Notes:
1 All specifications valid at 23ºC ± 2ºC (73.4ºF ± 3.6 oF) with an FC/PC connector, unless otherwise specified.
2 Typical dynamic range with a three-minute averaging at SNR = 1 (for 400-SD34/SD37/SD135/ST37/ST137, typical dynamic range
with 45-second averaging is only 1 dB lower than values given for three-minute averaging).
3 Typical dead zone of multimode modules for reflectance below -35 dB using a 10 ns pulse.
4 ORL measurement not available for this module.
5 Typical dead zone of single-mode modules for reflectance below -45 dB, using a 10 ns pulse (5 ns pulse for 400-SD34/SD37/SD135/ST37/ST137).
6 Typical dead zone of 400-SD34/SD37/SD135/ST37/ST137 single-mode modules for reflectance below -55 dB, using a 5 ns pulse.
7 Typical dynamic range on NZDS fiber with a three-minute average at SNR = 1.
8 Does not include uncertainty due to fiber index and sampling resolution.
9 Typical output power value at 1550 nm.
10 Typical dynamic range at 1550 nm for the 400-SD40 configuration is 2 dB lower at 10 µs and 1 dB lower at 20 µs.
11 Typical dynamic range at 1550 nm for the 400-SD45 configuration is 2 dB lower.
