Fiber Optic Cable
Fiber optic cable must be handled carefully during installation. Every cable has a minimum bend
radius, example, and fibers will be damaged if the cables are bent too sharply. It is also important not to
stretch the cable during installation. Extreme Networks recommends that the bend radius for fiber optic
cable equal 2 inches (5.08 cm) minimum for each 90-degree turn as shown in
NOTE
Kinks and sharp bends can destroy or impair the cable's ability to convey light pulses accurately from one
end of the cable to the other. Use care in dressing the optical fiber cables: provide satisfactory strain relief to
support the cable and maintain an adequate bend radius at all cable turns, particularly where the cable connects to
the I/O module.
