Abstract
To send a service to the
customers required network access. If using copper wires only gained
access speeds capable of delivering a maximum of up to 4 Mbps, while customer
demand for services has increased and bandwidth copper cables are not able to
distribute it. With optical fiber capable of delivering up to 100 Mbps
bandwidth with technology-based multi-service access node (MSAN) and is able to
meet customer needs.Therefore modernization of copper access network with fiber
optics. After the modernization of the copper access network into an
optical fiber, optical fiber can meet the needs of customers with the quality
of service improved.After his imodernisasi greater bandwidth and higher speed
from 4 Mbps to 100 Mbps. Applications obtained customers also varies. Easier
installation of optical fiber, the optical fiber measuring instrument needs to
use two types of measuring devices only. With the cost of optical fiber is
cheaper than copper cables and optical fiber capacity is also large. Then
the system becomes simpler, smaller optical cable placement will seem easier
and neater, dimensions and does not require extensive land.
1. Comparison between
copper and fiber optic
2. Step - step
modernization
Namely the modernization of
the network upgrade existing customers to MSAN, both of which are still the
copper access network using the customer terminal networkdengan RK terminal or
network access that customers already using the ONU (Optical Network
Unit). The step - step modernization of the copper cable into an optical
fiber, namely:
a. Project
Management. Outlining the work to be done, make networkdiagram.
b. Survey, Planning
and Design OSP, and DRM (Design Review Management).
c. Procurement and
installation of the primary cable FO (from STO sd ODC).
d. Procurement and
Installation of secondary cables FO (of ODC sd ODP).
e. Procurement and
installation Drop CableFO (from ODP sd OTP / rosette).
f. Integration with
existing fiber optic cable, the existing grounding system and with other sub
systemtelekomunikasi.
g. Site acquisition
for placement ODC / OTB (either in the field or in the halls / high rise
building).
h. Testing / testing
characteristics of the fiber optic cable.
i. Necessary permits
from third parties.
j. Gradually
installing fiber optic ranging from MDF, installed near the MDF.
k. Installing ODC near
RK, from ODF to ODC feeder connected with fiber optic cable.
l. Installing ODP near
DP, from the ODC to ODP connected by optical fiber distribution cables.
m. Installing OTP near
KTB, from ODP to OTP connected by fiber optic drop cable.
n. Then OTP home
customers connected with fiber optic cable indoor and home customers connected
to the fiber optic splitter.
o. Existing copper
cable is replaced with an optical fiber that has been installed and connected
to the terminal splitter customers, and most users of optical fiber to the
customer is a residential and business community.
3. Device for modernization
The device used for the
modernization of a copper cable to optical fiber there is 3, namely:
a. MSAN (Multi
Services Access Network) MSAN is a device that serves multiple access network
services, network access platform that provides a public service to provide
broadband services and narrowbanddalam PSTN and NGN networks.
b. DSLAM (Digital
Subscriber Line Access Multiplexer) is an equipment that serves to combine and
separate the data signal with phone lines used to transmit data.
c. Metro Ethernet is a
network that connects geographically separated LANs over the WAN
provided by a service provider.
4. Needs Analysis bandwidth
One reason modernize the
copper access network into an optical fiber up to the customer to which the
growing need for services bandwidthuntuk. Bandwidth requirements on copper
and fiber optic cables, namely:
a. With copper cable
(other systems) Bandwidthkabel copper: 4 Mbps
Application:
-. Phone requires 4
Khz
-.Internet Need 64
Khz
b. With fiber
optics
Bandwidthserat optics:
150-600 Mbps
5. Analysis of the needs of
measuring instruments
The main tool that is
needed in carrying out trouble shooting transform and disruption of the access
network because without using a measuring instrument can not do anything -
anything against disturbance.
- With copper cables
measuring instruments used are:
a. Continuity Tester /
Cable Identifier for cable continuity measurements.
b. AVO meter / Digital
Multimeter for measurement of electric current, electrical voltage
measurements, measurements resistant meshes (loop), the measurement screen
prisoners, continuity channels.
c. Megger (Insulation
Tester) for the measurement of insulation resistance.
d. Grounding Tester
for measuring prices pentahanan prisoners.
e. Fault Locater to
locate the point of cable damage and look for cable routing.
6. Cost Analysis
One more reason to
modernize the copper access network into an optical fiber through which the
costs to customers.
a. With copper cables,
costs - the costs involved are:
-. Price 1 m USD pair
copper cable. 50, -
-. Cost Rp. 50,
-
-. Price 3 km cable
pair is $ 1200 (50 + 50) x 3000 x 1200 = Rp. 360,000,000, -
b. With fiber optics,
costs - the costs involved are:
-. Prices fiber optic
12 nerves (capacity 12 x 40,000 channels) of Rp. 50.000, - / meter.
-. Price for 3 km is
Rp. 150.000.000, -
7. Conclusion
From the results of the
modernization of the copper access network into an optical fiber to the
customer, it can be concluded as follows:
a. After the
modernization of the copper access network into an optical fiber to the
customer, optical fiber capable of delivering bandwidthhingga 100 Mbps by using
MSAN technology.
b. With the cost of
copper wire needed for a distance of 3 km is Rp. 360,000,000, - with a
capacity of fiber optic bandwidth20 Mbps while the cost for a distance of 3 km
is Rp. 150.000.000, - with a capacity bandwidth100 Mbps.So in terms of
cost and capacity of fiber optic bandwidth use more profitable.
c. In the optical
fiber part becomes much simpler system, the placement of smaller optical cable
would seem easier and neater, does not require the dimensions and extensive
land.
