Wiring Sumatera

Looking at the telecommunication infrastructure in western Indonesia, Jawa-Bali and
Sumatera are counted among the bests. Long distance transmission across the island is mainly served by terrestrial fiber optic links, which are approximately described in the picture below. This is based on the infrastructure of the three largest telecom operators PT. Telkom, PT. Indosat and PT. Excelcomindo (both existing or under development). The cable owned by PGASKOM (PGN) and possibly that of other operator(s) are not displayed yet. Several links might be inaccurate e.g. the link Pekanbaru-Padang (ISAT?) or Pekanbaru-Pariaman (XL?). Looking at this, to my opinion :

• Without participation from the three big telcos mentioned above, the possibility to "festoonly wire" Sumatera as in the Palapa Ring proposal is not very high; it likely might not be happened :-)
• These telcos are already on the "right" track with regard to infrastructure; they just have to put more "professionalism" in utilizing their optical backbone and not only to focus on competition for gaining more cellular/mobile subscribers
