Cable compressive force- The cable can buckle under the compressive forces of a cable pusher and become crushed from additional sidewall forces that build up on the inside of a bend. This can also lead to a pulling force built-up that limits the distance it can be pushed. If a cable pusher is used to assist cable placing as it enters the sub-duct and if it continues to work if a cable jam occurs, the compressive force could cause the cable to buckle, unless the placing engine is adjusted to stop pushing when cable compressive load reaches a set safe level. Fiber Optic Cable stiffness in bends and undulations in the duct trajectory- The greater the cable stiffness, the larger the frictional force from cable stiffness in bends and undulations in the duct.

7.1 Normal Cable Pulling Method

If cables are pulled into conduit or innerduct, the maximum cable diameter attempted will normally not exceed 50 to 60 percent of the conduit or innerduct Id . Table 9 contains the fiber count of the largest conventional Sterlite fiber optic cable that can be pulled into innerducts of various sizes using a fill ratio of 50 and 60 percent.

3FILL RATIO = Where: d = outside diameter of cable and, D = inside diameter of micro-duct

Table 9– Maximum Fiber Count of conventional Sterlite Fiber Optic Cable that can be placed into various sized Innerducts

Before the cable placing operation begins, the innerduct or micro-duct system should be checked to be assured that the cable's minimum bend radius is not violated during handling, feeding, placing, and final positioning. The placing quipment and all pressure fittings should be checked. The winch shall be adjusted to stop placing the cable if the placing load reaches a level close to the maximum rated cable placing tension. If a placing engine is used, it should be checked to confirm that the compression limits safely match the limits of the cable being placed and have been properly and accurately set. Radios should be checked to confirm that all manned positions along the right-of-way are in communications and prepared to start the placement. Figure 6 shows a typical unassisted standard optical cable pulling operation.

What are the prospects for a massive FTTH rollout? We believe that a major deployment is unlikely for the foreseeable future, for several reasons.

First, the cost calculations require essentially monopoly conditions. The major cost of the FTTH network is in the installation of ubiquitous distribution fiber that permits a drop to any potential customer. That fixed cost of passing every customer must be borne by the fraction of customers who actually subscribe. If the "take rate" in a competitive market is 25 percent, for example, then the effective cost per customer is nearly four times the cost in a monopoly situation.

Costs for today's services are well-known, and markets are competitive for new entrants. Thus, new providers would have no pricing power-and lenders or financial markets will not permit the stranding of capital in the new, post-telecom-crash environment.

That favors greenfield approaches in which the FTTH build can be justified on costs and the fiber's capacity would dissuade a competitor from trying to overbuild. A second network would presumably cap the take rate at 50 percent for each. Thus, tied to low capital turnover rates, it would take 30 to 50 years for FTTH to become prevalent. Even then, a monopolist owner would have to subsume its competitor's business-a challenge for businesses as disparate in their technologies and practices as entertainment and telecommunications are.
