This document discusses the capital and operational costs of fiber-to-the-home (FTTH) deployments. For capital costs, civil works like laying fiber optic cables comprise around 70% of expenses. Reducing civil works through efficient right-of-way planning can significantly lower initial costs. Operational costs are harder to compare between technologies but point-to-point FTTH architectures have advantages like easier traffic management and troubleshooting physical layers that may reduce operating expenses over the long run, despite some disadvantages like requiring more space in network hubs.

2. INTRODUCTION
 Here we deals with tow considerations of
cost as below :
 Capital Cost
 Operation Cost

3. 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.

4. Typical initial capex distribution for
greenfield FTTH deployments

5. 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

6. 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.

7. 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 management
2. no encryption
3. ease of trouble-shooting the physical layer
4. easy upgrade to higher speeds/new
technologies on a per-customer basis.

8. 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.
