Introduction to the transmission distance of optical modules
The transmission distance of an optical module is mainly limited by loss and dispersion. Loss occurs because the light energy dissipates due to medium absorption, scattering, and leakage during optical fiber transmission, dissipating energy at a certain rate as the transmission. Application Field: SR modules are the workhorses of data centers, facilitating high-speed connections for intra-data center communication. Among them, long-distance optical modules refer to optical modules with a transmission. After transmission through the optical fiber, the receiving interface converts the optical signals into electrical signals using a photodetector diode and outputs electrical signals of the corresponding bit rate after pre-amplification. ≥30km is long distance transmission.
