Accessories and Tech Data
Many commercial and industrial environments present electrical noise and ground
differential challenges, especially over long distances. Fiber optic links solve
those problems, providing high bandwidth connections that are impervious to
noise and ground differentials. Papyrus Computer Technologies Ltd. has fiber
optic solutions that support point-to-point and networked systems. We also
provide the couplers and cable assemblies needed to put the complete system
together, and we can manufacture custom length plenum-rated simplex cable. If
you have questions, give our Technical Support team a call. They can help.
Quick Facts
Optical fibers propagate light signals by the principle of ‘total internal
reflection’. Signals introduced into the fiber, stay in the fiber, refracted by
the difference in refractive index between the core and cladding of the fiber.
Graded index multimode optical fibers are manufactured with a gradual change of
refractive index from core to cladding, They provide better cost/performance
than step index fiber while still maintaining relatively large core diameters,
which are easier to couple.
Tech Tip: It is important to check fiber optic cables for
continuity both on the roll and after installation. Our Electronics’ DXL10 Fiber
Optic Cable Continuity Test Tool connects to one end of a fiber optic cable,
projecting light into the cable that is bright enough to be seen at the other
end, but won’t hurt your eyes.
