Extreme Networks Summit X150 Series Hardware Installation Manual page 160

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 the following figure.
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.
