Russian regional operator Sibirtelecom has announced plans to invest RUB3.4 billion (USD110 million) in the expansion of its Gigabit Passive Optical Network (GPON) network this year. The operator launched its GPON project two months ago in the cities of Novosibirsk, Omsk and Krasnoyarsk. The operator claims over 5,000 subscribers to the GPON network. Further GPON networks will be launched in Tomsk and Kemerovo later this year. Sibertelecom was the first in Siberia to introduce GPON technology to the region. By the end of the year it hopes that GPON pilot zones will appear in many regional branches of Sibirtelecom. According to TeleGeography’s GobalComms Database, Sibertelecom is the fourth largest of Russia’s mega-regional fixed line operators in terms of subscribers and the third largest by revenue. It operates in Siberia, an area covering 29% of Russia’s territory and containing 13.8% of its population.
