OTNS8600-OLS Open Line System

  • otns8600 ols open line system 1

OTNS8600-OLS is an optical line system designed by Guangzhou Sintai for open transport network architecture, aiming at treating the WDM line system at optical level as a whole and realizing decoupling from the electric layer, and it is a highly-integrated box product integrating the functions of VMux, Demux, OA, OTDR, OCM, OLP, OSC, and TDC into a whole; It can satisfy end-to-end management and rapid service sending, and combine with service protection, optical cable monitoring, channel performance monitoring and other functions to realize transparent service transmission and convenient operation and maintenance; it aims to build an ultra-wide and non-obstructive, flexible and efficient, intelligent and open DCI network for customers.
