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
Standard FiberPatrol cable (p/n FPSP04XX - XX = number of fibers)
typically includes 12, 24, 36, or 48 optical fibers inside 1, 2, 3, or 4 gel
filled buffer tubes. The number of tubes and the number of fibers inside
each tube may vary, depending on the specific cable used at the site.
However, the basic cable construction and specifications are fixed
regardless of the number of tubes/fibers.
