Routing the Cables

Routing Fiber Optic Cables

Introduction

The routing of fiber optic cables requires different considerations than the routing of wire cables, due to the delicate material of the transmission line.

Minimum Radius

The following table gives the minimum bend radius for several types of fiber optic cable:

Cable/Fiber Type

Number of Fibers

Minimum Bend Radius

Minimum Bend

(normal handling)

Radius (static load)

 

 

 

 

 

 

Simplex

1

35 mm

50 mm

 

 

 

 

Duplex

2

70 mm

140 mm

 

 

 

 

Quad

85 mm

160 mm

 

 

 

 

Note: The minimum radius must be maintained at all times, including while routing the cable and managing slack cable.

Rack Standoff Brackets

To ensure that the fiber optic cable is properly secured to the chassis, a rack-mounted bracket may be used to support the fiber optic cable. Nortel does not supply a bracket for this purpose.

Securing and Wrapping Fiber Optic Cables

Fiber optic cables can be secured with tie wraps, if not applied too tightly. Your application may also require the fiber to be wrapped in a protective paper. Tie wraps must be fitted in accordance with Nortel Work Standards WS-001 and WS-4024.
