Wavelength division multiplexing system

摘要

A wavelength division multiplexing system (1) includes a wavelength division multiplexing transmission path including a multimode optical fiber (2) that is codoped with germanium and fluorine. The wavelength division multiplexing system (1) may further include a multiplexer (3) and a demultiplexer (4), in which the multiplexer and the demultiplexer are coupled via the multimode optical fiber (2). The wavelength division multiplexing system (1) may further include a first multiplexer/demultiplexer (6) and a second multiplexer/demultiplexer (7), in which the first multiplexer/demultiplexer (6) and the second multiplexer/demultiplexer (7) are coupled via the multimode optical fiber (2) so that a bidirectional wavelength division multiplexing is enabled.
