High NA, Bend-Insensitive Fibers for Acoustic Sensors and Fiber Hydrophones

Fibercore's specialty singlemode fibers have been used for many years in acoustic sensors and fiber hydrophones in sub-sea environments. The high-strength 2% and 3% proof-test options available on Fibercore’s bend-insensitive SM-series make them ideally suited for high-reliability fixed or towed (streamer) hydrophone arrays. The low-profile 80 µm variants and ultra-low profile (50 µm) of the SM1500 (4.2/50) deliver further enhancements to both lifetime and bend-insensitivity.

Our new range of polyimide-coated singlemode fibers have been designed specifically for the highly challenging environment of downhole sensors. Using the same polyimide coating of our HB-P fiber range, these fibers offer the bend insensitivity and photosensitivity of our high NA Singlemode fibers with the added benefit of being able to withstand short-term temperatures as high as 400 degrees C (and 300 degrees C continuous).
