WARNING
Use care when working with exposed optical fibers. The bare fibers are
125 microns in diameter and can easily penetrate skin.
Always wear safety glasses when working with optical fibers.
Always dispose of bare fibers in a sealed and labeled container that is
specifically designed to contain fiber optic waste.
NEVER dispose of bare fibers in a standard waste receptacle.
Note
The sensor cable (p/n F4SP0101) includes 12 optical fibers inside a gel
filled buffer tube. Custom sized cables are also available with additional
fibers (contact Senstar for details).
Note
Fusion splice performance typically results in a loss of between 0.01 and
0.03 dB.
