Maximum fiber optic distance between optical modules

SFP distance refers to the maximum effective range over which an SFP optical module can transmit data while maintaining signal integrity. An SFP (Small Form-factor Pluggable) module transmits data over fiber using specific wavelengths and power levels, which directly influence how far the signal can travel before degradation occurs. This is why two.
