Abstract

Abstract: The Qinghai-Tibet plateau’s odious natural environment of high altitude, extreme low temperature and great temperature difference has severe impact on the loss characteristics of OPGW, and threatens its long term safe and stable operation. This paper introduces the ultra high-performance OPGW used in the Qinghai-Tibet DC transmission interconnection project. Customized by the use of SMF-28 ULL fiber and low temperature resistant optical fiber ointment, the OPGW has low loss characteristics in the ultra low temperature of -55 ℃ and has been successfully used in the world’s highest ultra long-span optical fiber communication system which crosses over the Tang-ku-la Mountains with a distance up to 295 km. Application shows that the OPGW can operate stably in the poor natural environment of plateau area. The development and application of ultra high performance OPGW provides a good foundation for the long term safe and stable operation of the communication system of the Qinghai-Tibet DC transmission interconnection project and valuable experiences for similar projects in the future.

Key words: OPGW, ultra low loss, optical fiber communication, DC transmission interconnection
