Dual fiber drive system

A laser source suitable for driving single mode and multimode fiber communication lines. The driver circuit includes a photo diode that, in multimode operation, responds to the laser light and causes the laser's output amplitude and wavelength to rapidly fluctuate thus producing the incoherent...

Summary:A laser source suitable for driving single mode and multimode fiber communication lines. The driver circuit includes a photo diode that, in multimode operation, responds to the laser light and causes the laser's output amplitude and wavelength to rapidly fluctuate thus producing the incoherent light required to drive multimode fiber. In single mode operation, the photo diode is disabled and the laser produces the requisite coherent light.
