Distributed fiber sensing interrogator with detachable end

Abstract

Aspects of the present disclosure describe systems, methods and structures for distributed fiber sensing systems including interrogator and attached fiber in which the interrogator includes a common line card and function-specific, pluggable front end in which the line card is configurable and supports different signal processing paths and automatically senses the front-end type and uses corresponding firmware/software or signal processing path(s) to process sensed data.

Dependencies are inferred from the claim text.
