SM and MM Fibers
SM fibers are better suited for moving information across longer distances and are routinely used by tele
-
communications. In comparison, MM fibers are ideal for local networks due to their low cost and greater
bandwidth.
9.8. General Fiber Optic Cables Handling Instructions
•
Wear finger cots or gloves. Your hands may look clean, but dirt and oils on them can damage the
fiber and contaminate connectors.
•
Never use the fiber pigtail to pick up or support the weight of the device. Keep both the device and
the optical connector together in your hand(s).
•
The fiber is made of a very pure expensive glass. Treat it with the same care that would be used
when handling expensive crystal glass.
•
Do not allow kinks or knots to develop in the fiber. Do not pull on the fiber when kinks or knots are
present. Pulling will only cause knots, kinks, and curls to tighten and exceed the minimum bend
radius.
•
Always use the correct tools for stripping and cleaving the fiber. It will save time and reduce
breakage caused by scratches.
•
Follow all ESD precautions.
