COST CONSIDERATIONS

INTRODUCTION

Here we deals with tow considerations of cost as below :

Capital Cost Operation Cost

CAPITAL COST

FTTH deployment involves a number of different cost components that can each be individually optimized

Figure in next slide shows a typical cost distribution for greenfield FTTH deployments.

Typical initial capex distribution for greenfield FTTH deployments

CAPITAL COST

The last graph confirms what intuitively could be expected: civil works comprise almost 70% of the total initial capex.

Obviously, this is the cost component where saving efforts have the largest effect.

Therefore, usage of every potential right-of-way solution should be considered in order to reduce this component

OPERATION COST

Operation costs are a multi-faceted subject. Most of these cost items are not specific to any particular access technology, like marketing, subscriber acquisition, and subscriber management.

It is very difficult, though, to quantify operational cost differences. Therefore, we try to identify qualitatively the technology and architecture dependent aspects that can impact the operation cost of an FTTH access network.

OPERATION COST

Aspects which are favorable for point-to-point deployments are mainly due to the relative simplicity of the architecture, as there are;

1. ease of traffic management2. no encryption3. ease of trouble-shooting the physical layer4. easy upgrade to higher speeds/new

technologies on a per-customer basis.

OPERATION COST

Certainly, there are also some operational disadvantages of point-to-point deployments:

1. More real estate in the POP location due to the more extensive fiber management

2. Slightly more space requirements for the active equipment.

3. Higher power consumption in the POP as every active subscriber is connected to a dedicated port, although this aspect is mitigated by the penetration rate.
