Fiber Optic Temperature Sensing and Measurement
Luna’s distributed and multipoint fiber optic temperature sensing systems provide precise thermal measurements in environments where conventional thermocouples and RTDs may be difficult to install or affected by electrical interference. Continuous and discrete sensor options support high-resolution thermal mapping, process monitoring, material testing, and long-range asset monitoring, delivering unprecedented spatial detail and data without sacrificing precision and sensitivity.
What Is a Fiber Optic Latency Test?
A fiber optic latency test measures the time required for an optical signal to travel through a fiber cable, assembly, or network. Because transmission delay is directly related to the optical path length and the fiber’s refractive index, precise latency testing can also be used to verify fiber length and compare the performance of different optical links.
Luna’s optical backscatter reflectometer (OBR) systems use optical frequency-domain reflectometry to measure optical delay and length with picosecond-level precision. These measurements support high-speed trading network certification, production testing of precision fiber links, data-center diagnostics, and systems that depend on accurately matched optical paths.
