Abstract
A system for calibrating the external strings located at a distance of ∼100 m from the core of the NT-200+ deep-water neutrino telescope on Lake Baikal is described. The calibration system is composed of nanosecond light pulsers based on ultrabright blue LEDs. It is shown that the accuracy in synchronizing the external strings with the central part of the telescope, attained using this system, is 1 ns or better.
