Optical module distance
Optical modules generally have the following specifications: multi-mode 550m, single-mode 15km, 40km, 80km and 120km and so on. Loss and dispersion: the two mainly affect the transmission distance of the optical module. 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. Let's take a look below! Optical module parameters Center wavelength: the unit of center wavelength is nanometer (nm), currently there are three main types: 1) 850nm (MM, multi-mode, low. Do you really need a 10km module for a 300m connection? Many customers unknowingly overspend by not matching transceiver distance with real needs. Short-distance transmission usually refers to distances below 2km, medium distances range from 10-20km, and distances greater than or equal to 30km are considered long-distance. The operating wavelength of an optical module is a range measured in nanometers (nm).
