of the peer device on the other side. Attach a label 2 cm (0.79 in.) away from
the end of an optical cable.
Step 3 Lay out the new cable.
Lay out the new cable in the same way as the old one. Note the following points:
● Lay out optical or SFP+ cables in the cabinet according to installation
regulations. You are advised to arrange new cables in the same way as
existing cables. Ensure that cables are routed neatly and intact.
● Separate optical or SFP+ cables from power and signal cables when laying out
the cables.
● Bend an optical or SFP+ cable with a bending radius of at least 4 cm (1.57 in.)
to prevent damage to core wires. Ensure that the cable is intact. Ensure that
optical or SFP+ cables are laid out for easy maintenance and capacity
expansion.
● Bind optical cables with cable ties. Ensure that optical cables are bound
closely, neatly, and straight, and cable ties are in even distance and fastened
properly.
