How to label the transmission distance of an optical module
SFP distance refers to the maximum effective range over which an SFP optical module can transmit data while maintaining signal integrity. If the optical module works at a wavelength near 850nm (880nm) or 910nm (940nm), then the module is a multi-mode fiber (MMF) optical. In reality, SFP transmission distance is defined by optical design—not data rate. 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. xxx: indicates the rate and rate standard. The module is used for high-speed cable (copper cable) connection. Optical modules can be divided into: 100Mbps optical modules: Usually labeled as 155M, 100Base, FE, etc.
