Product Overview
The multimode optical fiber is a 50µm graded-index core fiber engineered for high-reliability use in reservoir monitoring and distributed sensing applications. Designed with a robust SIL/PFA (Silicone/Perfluoroalkoxy) coating and precision-manufactured by Sumitomo Electric, this fiber enables long-range, high-bandwidth optical communication in thermally and chemically aggressive well environments.
Ideal for integration into DTS, DAS, and FBG sensor systems, this fiber meets the stringent requirements of permanent well installations and field-hardened optical networks across upstream production systems.
