Optically Powered Low-Energy Demarcation Device for Monitoring FTTx Networks

We demonstrate an energy-autarkic FTTx monitor. A special protocol and sophisticated hardware reduce the electrical operating power to 0.7µW, which can be delivered by an optical supply signal of only 5µW/monitor at a separate wavelength. ©2010 Optical Society of America OCIS codes: (060.0060) Fiber optics and optical communications; (120.0280) Remote sensing and sensors; (060.4250) Networks; (060.4256) Networks, network optimization
