After a fiber is installed well, the bend radius must be not less than 10 cm (3.94 in).
To pass a fiber through a metallic board hole, make sure the hole has a sleek and fully filleted surface
(the filleting radius must be not less than 2 mm, or 0.08 in). To pass a fiber through a metallic board
hole or bend it along the acute side of mechanical parts, make sure the fiber wears jackets or
cushions.
Insert and remove a plug with care. Never exert a fierce force to the fiber or plug; otherwise the plug
might be damaged or the fiber might be broken. Never pull, press or extrude the fiber fiercely. For the
allowed maximum tensile load and crush load, see Table4-4.

WARNING!
Do not stare into any fiber ports when you connect an optical fiber. The laser light emitted from the
optical fiber might hurt your eyes.
