Appendix C Cabling

When the RG-PF2920-DPBOX-P is installed against a wall, the following cable requirements must be met.
7.1 Requirements for the Cable Bend Radius

The bend radius of a fixed power cord, network cable, or flat cable should be over five times greater than
their respective diameters. The bend radius of these cables that are often bent or plugged should be over
seven times greater than their respective diameters.

The bend radius of a fixed common coaxial cable should be over seven times greater than its diameter. The
bend radius of the common coaxial cable that is often bent or plugged should be over 10 times greater than
its diameter.

The bend radius of a fixed high-speed cable (such as SFP+ cable) should be over five times greater than its
diameter. The bend radius of the fixed high-speed cable that is often bent or plugged should be over 10 times
greater than its diameter.
7.2 Requirements for the Minimum Bend Radius of an Optical Fiber

The diameter of a fiber tray to hold fibers should be over 25 times greater than the diameter of the fiber.

When an optical fiber is moved, the bend radius of the fiber should be over 20 times greater than the diameter
of the fiber.

During cabling of an optical fiber, the bend radius of the fiber should be over 10 times greater than the
diameter of the fiber.
