Extending the sensing range of Brillouin optical time-domain analysis up to 325 km combining four optical repeaters

Luc Thévenaz, Sang Hoon Chin, Flavien Gyger

A novel scheme is proposed to extend the sensing range of Brillouin optical time-domain analyzers (BOTDA). Specially-designed erbium doped fiber amplifier (EDFA) repeaters are located every 65km fiber along the sensing cable to achieve a total sensing leng ...

Extending the Real Remoteness of Long-Range Brillouin Optical Time-Domain Fiber Analyzers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Sang Hoon Chin

The real remoteness of a distributed optical fiber sensor based on Brillouin optical time-domain analysis is considerably extended in this paper using seeded second-order Raman amplification and optical pulse coding. The presented analysis and the experime ...
