OptiX OSN 550 Multi-Service CPE Optical Transmission System

The OptiX OSN 550 is new-generation optical transmission equipment. It is used at the access layer of a transmission network, supporting the multi-protocol label switched (MPLS) technology and a variety of service network topologies in the TDM and packet domains.


The OptiX OSN 550 adopts the dual-core architecture (TDM and packet) and supports various service access modes.


Dual-Domain Architecture and Multi-Service Transmission

The OptiX OSN 550 supports service bearing in both time division multiplexing (TDM) mode and packet mode. With dual-domain networking, the OptiX OSN 550 achieves smooth evolution from TDM networks to packet switched networks (PSNs).



CES Functions and Flexible Networking

Circuit emulation service (CES) technology is supported by the OptiX OSN 550, which enables E1 TDM services in the pure packet domain to be directly received and transmitted. In this context, the TDM domain smoothly evolves to the packet domain.
