The cable manufacturer's recommended minimum bend diameter shall be maintained. If no minimum bend diameter is recommended, use the minimum diameter recommended below.

Cable under no load, Minimum bend radius 15 × Cable Diameter

Cable under load, Minimum bend radius 20 × Cable Diameter

6.4 Winches

Since optical cables are lighter in weight and smaller in diameter than their copper counter parts, smaller winches are generally used to place optical cables. Most standard size optical cables have a maximum cable placing force of 600 pounds or greater (some optical cables do have higher loads and some lower, consult the cable specification provided by Sterlite to determine the maximum placing load for each cable). Fiber optic cable winches tend to be smaller than the line truck bed winches used for copper cables. Capstan winches are popular. Some of these winches are stand alone, using portable power packs (electric or hydraulic) and some are truck or trailer mounted using the hydraulic power take-off from the support truck. Fiber winches should all have or be coupled to cable tension monitoring systems to ensure that the maximum cable tension is not violated. Slip clutches are often used for side take-off winches on line trucks.

6.5 Cable Blowing and Pushing Engine

The micro-duct system is based on the use of a combination of smaller diameter sub-ducts and more compact optical cables using more efficient placing methods and equipment specifically tuned to micro- duct and micro-cables. It is possible to use equipment similar to that used to place micro-duct cable to place standard size optical cables; it is specially tuned to the standard diameter optical cables and innerduct.

7. Cable Placing Methods

The force to install a cable into a duct is caused by sidewall forces between cable and duct, other adjacent cables (for ducts containing more than one cable), and the friction coefficient between the interacting materials. Micro-ducts and micro-duct cables are designed to optimize the fiber capacity of the available underground space. The placing methods discussed in this section have been developed to enable standard size optical cables and micro-duct cables to be placed efficiently, safely, and economically. Standard size optical cables, innerducts, microduct cables and micro-ducts can be placed using several procedures:
