OSN 7500

OptiX OSN 7500 Highlight:

★ Universal Switch Architecture for Multiservice Grooming
OptiX OSN equipment uses a universal switch architecture for unified grooming of packet services and TDM services.
OptiX OSN equipment can work in packet mode, TDM mode, or dual–domain (packet+TDM) mode.
★ Hierarchical OAM Facilitating Fault Detection
The Hybrid MSTP equipment supports hierarchical OAM to rapidly detect and locate various faults, thereby improving
network reliability. In addition, the Hybrid MSTP equipment supports distributed OAM and centralized OAM.
★ TP–Assist Solution Facilitating the O&M of Packet Services
Like the SDH equipment, Huawei Hybrid MSTP equipment supports a hierarchical operating & maintenance (O&M)
system by using the TP–Assist solution, so packet services can be configured, commissioned, or maintained in an end–to–
end manner.
★ Built–In WDM, Flexible Networking
The OptiX OSN equipment uses the built–in WDM technology to transmit several wavelengths over one optical fiber. In
this manner, the OptiX OSN equipment can be interconnected with the WDM equipment.
