Note: When connecting 40 km or 80 km single-mode fiber over a short
distance, we recommend putting an
attenuator to prevent the transceiver
from being damaged by excessive optical power.
Typical Distance: To reach the typical distance of a specified fiber
transceiver, please refer to the following formula: Link budget(dB) >
dispersion penalty(dB) + total link loss(dB).
