Introduction

OT120 series are a low cost and high performance optical line transmission equipment, witch combines up to four E1 channels into an optical data stream for transport over single mode or multimode fiber optic cables. Several transmitter options for different fiber cable types and wave-lengths are available. This optical line equipment is developed for transmission in access networks, corporate networks, dedicated networks for railway and power companies etc.
