Distributed Fibre Optic Sensing (DFOS), specifically RDTS systems are available in both single-ended and dual-ended configurations. A dual-ended fibre system can be more accurate due to the possibilities around correction of temperature dependent measurement errors caused by wavelength dependent loss (WDL).
Traditionally, two fibres have been used, laid side-by-side and connected at the far end using a turn-around.
OFS approach is to use a dual core fibre that is backward compatible to commercially available interrogator equipment.
Range features
A high level overview of what this range offers
- Spectral attenuation similar to commercially available single core 50/125 µm graded-index multi-mode fibers
- With the use of miniature turn-around device spliced directly to the dual core fibre, the mechanical reliability of the fiber is not compromised at any point
- Low optical crosstalk between the two cores of typically -50 dB with 35 mm fibre bend diameter
- Minimal fibre cross-section
- Low insertion loss over a wide wavelength range
