Optical fiber speed multiplexer

The utility model relates to an optical fiber speed multiplexer. The optical fiber speed multiplexer has main technical features of comprising a power supply module, a communication module, a core processing module, a user side signal converting module, and a line side signal converting module. The power supply module is externally connected with an AC power supply and supplies power for each module after converting the AC power supply into a DC power supply. The communication module is connected with the core processing module, the user side signal converting module, and the line side signal converting module, and controls the whole module. The core processing module is connected with the user side signal converting module and the line side signal converting module. The user side signal converting module is connected with a line side XFP module. The optical fiber speed multiplexer is reasonable in design, reduces requirements on wavelength of a WDM system, and saves cost to the largest extent. The optical fi
