Abstract

In many optical communication systems, it would be advantageous to use light transmission at two different wavelengths. One light wavelength could be modulated at high rates, e g 10 Mb/sec or higher, and carry normal Ethernet protocol signals whereas the second light wavelength could be modulated at a lower rate, e,g ,64 Kb/sec for voice transmission In order to lower system cost, it would be advantageous for a single detector to sense both signals
