An Optical Time Domain Reflectometer (OTDR) is a precision tool used to detect faults and measure loss along fiber optic links by analyzing backscattered light from high-speed pulses. Essential for both installation and maintenance, OTDRs ensure network reliability with accurate fault location, robust field performance, and intuitive operation.

Overview of optical communications via optical fibers including: signal conversion, optical fiber benefits, techniques like wavelength division multiplexing (WDM) for increased capacity, key components like optical amplifiers and spectrum analyzers for maintaining transmission quality.
This paper describes a compact optical channel monitor and a delayed interferometer having free-space optical elements such as lenses or mirrors, as an application of microoptics. These devices have been developed to be built into dense wavelength division multiplexing (DWDM) transmission systems. These optics use a Gaussian beam which is emitted through single-mode optical fibers and located near the optical axis. This paper explains the optical designs of these devices based on the Gaussian beam's behavior.
