Network Segmentation between core networks and user’s premises
• Long distance transit network (core networks) Thanks to rapid technology progress, the transmission capacity of the backbone trunk line such as terrestrial optical fiber, satellite (LEO,MEO, GEO), optical submarine cable is increasing tremendously. · Backhauling segment (middle range: <100Km) Optical fiber (WDM,DWDM, etc.), Wireless (3G, 4G, LTE, WiMAX ,etc.) · User access (last mile: <10Km) : Digital divide exist between developed and developing countries, urban and rural areas for the broadband data speed. · Multi-media services require last mile broadband data speed in particular for the developing countries (both urban and rural areas).
Case Studies of Optic Fiber Networks for providing various e-applications for smart city
Shiojiri (Japan) case • Optical fiber networks are built which connect 72 points
（Schools, City administrative branches, Hospitals, Museums, Nursing facilities, Kinder gardens, Industrial parks). Total length is 130 km. Public WiFi spots are interconnected. Fiber networks are built by government subsidy, however operated by city council with their own budget.
• Disaster mitigation systems are built deploying various sensors over the power saving Ad hoc wireless networks with 640 relay stations (debris flow, land slide warning, water level warnings, harmful bird and wild animal info., bus operation info., and children watch info. )
• City established Shiojiri Internet Connection Organization (Japan's first municipal provider with over 10,000 users) with open net concept. (because of private ISP’s usage charge was costly)

Case Studies of Optical Fiber Networks for Vitalizing the Rural community
Asturias -north Spain’s case (quoted from ITU-D contribution paper, Aggaros, Spain) • Public and Open FTTH Network • The initiative of the Government of Asturias,
northern Spain, to deploy an open FTTH network since the broadband services are perceived by all users as a basic service.
• This situation has led to Public Administrations to consider changing their traditional role and be more active, investing or promoting the investments on telecommunications infrastructures and services where a digital divide is present.
North Spanish case continued-1
Asturias • Asturias is a region in the north of Spain, with 1.15
million inhabitants in 0.49 million homes. Most population in concentrated in the three large cities, Oviedo, Gijón and Aviles. The economic activity is focused on Services and Industry.
North Spanish Case (continued-2)
• The Government of Asturias invested in deploying a high quality, future-proof broadband access network, open to all Service Operators, and supporting the present and future portfolio of services offered by those operators present in the region.
• The selected areas for network deployment were 27 municipalities located along 3 coal mining valleys, where economy needs to be shifted from primary sector to secondary and tertiary.
North Spanish Case (Continued-3) • The fiber network reaches all villages within the area with
more than 1.000 inhabitants (minimum target village size for deployment). The homes passed by the network have been 31,000 with 100,000 inhabitants in total.
• The Government of Asturias made the necessary investments to deploy the network and also the end user gateways to be leased to the Operators. The Public Infrastructure Operator (Aggaros) takes care of network upgrades, gateways and systems, and the costs of managing the network. The subscriber provision costs are responsibility of the Operators and Service Providers.
• The income for the Public Infrastructure Operator comes from leasing the service (fiber local active loop) to Operators and Service Providers. The charges include provisioning costs (initial installation fee) and monthly charge.
• there is a need for Public Administrations to invest in access networks infrastructure, if they want to address the digital divide and guarantee fair prices and service innovations in a true competition environment. Open networks are the best and only future proof solution.
Case Studies of Optic Fiber Networks for the Small Island Country (RMI)
Republic of Marshall Islands’ Case • The Marshall Islands are located in the North
Pacific Ocean some 4,000 kilometers northeast of Australia, consisting of 27 atolls and 5 islands. Land area is approximately 181 square kilometers scattered over 2 million square kilometers of territorial waters. Among the islands and atolls, there are only 4 islands and 22 atolls that are inhabited and Majuro is the capital.
• The total population is about 60,000 of which 60% resides on the capital, and 20% on Ebeye/Kwajalein (second urban center). The remaining 20% is scattered over 24 Atolls/Islands.
• Majuro already has underground core optical fiber backbone from Rita to Laura and hand holes every 1,000ft, and 8 nodes along the main road which are connected to MINTA’s main building. Optical submarine cable landed Majuro is linked with Guam via Kwajalein and has bandwidth capacity of 10 Gigabits with 70 Gigabits more to be added as demand increases.
• The present core backbone is branched and extended now to the limited number of customer’s premises by high speed FTTH on the occasion of recent Small Island Countries Forum in Majuro. Instead, low speed ADSs of 256Kbps are extended to about 1000 customer’s premises for collecting the traffic to be put through the Optical Submarine Cable, thus limiting to1% of the full capacity of submarine cable just like the small number of cars on the highway.
• If the high speed FTTH is extended to customer’s premises in Majuro like fishbone network in the very near future the submarine cable will be effectively used so as for MINTA to raise revenue from new emerging services such as VoIP, high speed internet services, digital IPTV, and e-application services.

RMI’s Case (continued-2)
Needs of Workshop for training of fiber networks and associated techniques
• General awareness training on optical fiber networks, digital communications and IP networks
• Basic knowledge on FTTX, FTTH to be extended to customer’s premises
• Training on fiber splicing techniques, in-house wiring and various necessary equipment and parts
• Training on outside optic fiber installation works
• 25 technicians participated in the two day fiber splicing workshop held last November at the MINTA’s (incumbent operator) training room
