u 1+1 hot stand-by redundant power supply
u Open architecture
It supports access via client sides of various manufactures equipment, as well as interconnection and intercommunication with many manufactures’ equipment.
u Transmission via regenerator
When the transmission range exceeds 80km, regenerator can be used to preamplifier, reshape and refit a time at various rates.
u The optical add and drop multiplex (OADM) function, able to add or drop at various rates.
u Flexible network management configuration and management style
It adopts SNMP-based graphical interface and supports management via in band or out of band. The network management system adopts an embedded operating system and has a real-time monitoring and controlling function. The form of management is flexible and varied, and graphical user interface is friendly.
