• When handling optical fibers, do not stand close to or look into the optical fiber outlet directly 

with naked eyes.

• Lead the optical fiber through a corrugated pipe. The mouth of the corrugated pipe must be 

wrapped with the adhesive tape. In the cabinet, the corrugated pipe should not be longer 
than 100 mm. In addition, the corrugated pipe is bound at the cabling aperture.

• The bending radius of the optical fiber should be more than 20 times the cable radius. In 

general, the bending radius of the optical fiber is more than or equal to 40 mm.
