First Building Block in an Evolving Series of Optical Signal Monitors
FiberLogix’s Power Monitor uses their All-Fiber patented Evanescent Field technology to provide
accurate, stable power monitoring over a wide signal range with minimal impact on signal quality.
Since the technology is non-invasive, i.e. the signal path is not interrupted, low insertion loss,
low PDL and Near Zero Back Reflection are assured.
The FiberLogix Integrated Fiber Optic Substrate (IFOS™) technology, using evanescent field
control, is uniquely suitable for integration at component and sub-component level to create
more complex units. For instance, the Power Monitor can be directly fused into other
components, such as AWG mux or demux, switches or VOAs to create cost effective, high
performance integrated components or modules. Contact FiberLogix direct to discuss your
