Long-distance modules are used to address high light attenuation
To compensate for signal attenuation over long transmission distances,long-haul optical modules (such as 40km and 80km modules) transmit at higher optical power. A 40km single-mode module can reach +2dBm, while the receiver's overload threshold is often only -3dBm. Unlike short-reach optics that operate over multimode fiber at 850 nm, long. Long-haul SFP modules and long-wavelength SFP modules are terms that can sometimes overlap but typically refer to different aspects of SFP (Small Form-Factor Pluggable) transceivers.
