Telkom's Backbone

Several times ago, I mentioned Telkom's national backbone in this post. According to records published by KOMINFO, as of Q4/2005 Telkom owns 10,816 km fiber optic cable. The backbone network is distributed as follows:

• Surabaya-Banjarmasin-Makassar : 2,088 km (constructed in 2000)
• Trans-Java : 2,605 km (2000)
• Jakarta-Medan-Batam: 2,990 km (2004)
• Batam-Singapore-Bangkok: 1,043 km (2004)
• Dumai-Melaka: 161 km (2005)
• Banjarmasin-Balikpapan : 955 km (2005)
• Makassar-Palu: 974 km (2005)

This information can be compared with that I have mentioned in other posts. This and those information can be complement to each other. For instance, for "Batam-Singapore-Bangkok" entry mentioned above, I would guess that it refers to TIS cable, which shall actually be excluded in the calculation since it is a consortium cable.
