National Fiber Optic Backbone

How does Indonesia's backbone currently look like ? How many kilometers of fiber optic cables are laid/buried/mounted nationwide? How are they distributed ? Some of you might already be confronted with such questions. I could not help you with exact answers either :-). But let us make some approximations. If we only consider the three biggest players (Telkom, Indosat, and Excelcomindo), after a quick and dirty calculation and some image processing efforts, I have the following estimates.

Long distance backbone of PT. Telkom (Source KOMINFO, 2007)

Long distance backbone of PT. Indosat (Source KOMINFO, 2007)

Long distance backbone of PT. Excelcomindo Pratama (Source KOMINFO, 2007)

PT. Telkom

• Jawa+Bali+NusaTenggara --> 2000+ km
• Sumatera --> 2200+ km
• Kalimantan --> 600+ km
• Sulawesi --> 500+ km
• Submarine (domestic) --> 3600+ km

PT. Indosat

• Jawa+Bali+NusaTenggara -->1500+ km
• Sumatera-->2400+ km
• Kalimantan-->600+ km
• Sulawesi-->100? km
• Submarine (domestic)-->3200+ km (SMW, APCN excluded)
  

PT. Excelcomindo Pratama

• Jawa+Bali+NusaTenggara-->2500+ km
• Sumatera-->1800+ km
• Kalimantan-->1000+ km
• Sulawesi-->1200+ km
• Submarine-->1700+ km
  

Given a certain margin, I would come to approximately 11,000 km for Telkom and around 10,000 km both for Indosat and for Excel (Any comments for this? :-)). This figures come under assumptions that a single span is only housed by a single cable. If we count some new long distance operators (ICON+,PGASKOM, Moratel, Napinfo etc.) and the emerging metro optical networks being deployed by many telcos and ISPs (above mentioned + Lintasarta, Biznet, CBN, etc.) I would come to a figure between 40,000 to 50,000 km!
