3 mm (0.11 inch)
Plan your fiber size according to the number of cards/ports installed in each side of the shelf. For
example, if your port combination requires 36 fibers, 3 mm (0.11 inch) fiber is adequate. If your port
combination requires 68 fibers, you must use 2 mm(0.7 inch) or smaller fibers.

1.11.2 Fiber Management Using the Tie-Down Bar

You can install an optional 5-inch (127 mm) tie-down bar on the rear of the ANSI chassis. You can use
tie-wraps or other site-specific material to bundle the cabling and attach it to the bar so that you can more
easily route the cable away from the rack.
