Cable Distances - Extreme Networks 12800 Series Hardware Installation Manual

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.
