Optical transmission loss
(max)
36.0 dB
#1
Transmission distance 2 m to 100 km
#2
2 m to 100 km
#1: When optical transmission loss is 16.0 dB or less, use an optical attenuator to
adjust the loss.
#2: For transmission over a 100 km distance, use a fiber optic with dispersion of 20
ps/nm/km or less.
