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).
