Optical module transmission distance and network speed
Optical modules for LAN networks can transmit data at rates of up to 10 Gb/s, while those for WAN networks can transmit data over distances of up to 80 km. In the rapidly evolving landscape of optical communications, Data Rate and Transmission Distance are the two primary metrics defining network performance. Understanding their key parameters isn't just technical jargon – it's critical for ensuring compatibility, performance, and reliability in your data center. 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.
