<p>The invention is a low cost Wavelength Division Multiplexing (WDM) system with a wide spacing for the component wavelengths. The system can employ uncooled lasers (11...11n) as the light sources, and may also employ more inexpensive polymer multiplexers/ demultiplexers (13,15). The wavelengths may also be allowed to drift, thus eliminating the need for passive gratings.</p> |
