Draft Final Report
Chapter 7 Outline of Scope of Works
(3) Scope of upgrade
The speed of the communications equipment introduced under the Project for the Urgent
Improvement of Communication Networks towards the achievement of Thilawa SEZ Class A will
be increased (to 10Gbps between Yangon and Thilawa), and reliability will be enhanced (by
introduction of optical fiber rings and L2 switch STP functions). Therefore, transmission equipment
(CWDM, 10GbE router) will be installed in the Thanlyin Station and optical fiber communication
lines will be laid to Thilawa SEZ. An outline of the Thilawa SEZ communication equipment is
shown in Figure 7.1-23 and a map of the target area is shown in Figure 7.1-24.
The Thilawa SEZ development plan is currently ongoing. The plot has not been decided yet and
the electric power supply system plan is still undecided, so a design was drawn up based on the
following preconditions.
1)
Precondition 1: Basic topographical data
Class A area: 400ha = 4km2 (interviews with the trading company consortium who are
the Thilawa SEZ developers) (Reference: SEZ area: 2,400 ha = 24km2)
Class A final planned population 40,000-50,000 (Same as above) (Reference: SEZ
population: 333,600)
2)
Precondition 2: Preconditions for deciding line configuration
For the foreseeable future, no power supply will be available around Tilawa SEZ.
(Marine University and Thanlyin Station have a power supply)
Incoming tenants will be responsible for SEZ internal line construction, line application, etc.
whenever required.
3)
LTE installed in Marine University under grant aid cooperation will also be utilized.
Consideration will be given to providing FTTx services in future.
The transmission route between SEZ and Yangon city will adequately meet Class A demand.
The transmission route will have a highly reliable line configuration.
Line configuration
The transmission equipment will be connected to the existing fiber optic cable in Thanlyin
Station and a transmission route for Yangon = Thanlyin = Thilawa SEZ will be installed.
The transmission route will be a loop configuration using fiber optic cable.
The necessary switches, etc. for loop configuration will be installed in Marine University.
(Reason: Time until transmission route construction and cost can be reduced by adopting
this method.)
(4)
Equipment to be introduced
The main equipment required for construction of the Thilawa SEZ communication facilities is
as shown below.
(a) CWDM multiplex transmission equipment x 2 (Note: CWDM will not be necessary when
DWDM of 30 Gbps is installed in Thanlin station planned under Yangon Metro network
