Note: WDM-type SFP modules must be used in pairs (e.g., SFP-1G10ALC and SFP-
1G10BLC).
Note: When connecting the SFP-40A and 40B, we recommend using an attenuator to
prevent damage caused by excessive optical power.

prevent damage caused by excessive optical power.
Typical Distance: To reach the typical distance of specified fiber transceiver, please
refer to formula: Link budget(dB) > dispersion penalty(dB) + total link loss(dB)
