It provides a robust and scalable solution for metro access and aggregation layers, making it ideal for service providers looking to deliver reliable, high-speed connectivity across urban and suburban networks.
Built with a universal switching architecture, the OSN 1500 supports both TDM and packet-based transport technologies, allowing seamless integration of traditional SDH services with modern Ethernet and IP-based applications. This hybrid capability not only ensures smooth service migration but also protects legacy investments while paving the way for future service evolution.
The system is capable of handling a broad spectrum of services including SDH, PDH, Ethernet, ATM, SAN, and video transmission, making it a truly multi-service transport platform. It supports a variety of network topologies—such as ring, chain, star, and mesh—offering high flexibility in deployment across diverse environments.
Equipped with intelligent management and built-in protection mechanisms, such as SNCP, MSP, and ASON-based restoration, the OSN 1500 ensures high availability and carrier-grade reliability. Whether deployed in a mobile backhaul scenario, enterprise network, or public service infrastructure, the Huawei OptiX OSN 1500 delivers consistent performance, efficient bandwidth utilization, and simplified operation and maintenance, aligning with the strategic goals of next-generation network evolution.
The OSN 1500 employs a universal switch architecture, enabling it to operate in packet mode, TDM (Time Division Multiplexing) mode, or a hybrid of both. This flexibility allows for seamless integration of legacy services with emerging packet-based applications, facilitating a smooth transition for network operators.
Designed to handle diverse service types, the OSN 1500 supports SDH, PDH, Ethernet, ATM, SAN, video, and more. This comprehensive service support ensures that operators can deliver a broad spectrum of offerings to meet various customer requirements.
With integrated Wavelength Division Multiplexing (WDM) capabilities, the OSN 1500 can transmit multiple wavelengths over a single optical fiber. This feature enhances bandwidth utilization and allows for flexible networking with existing WDM equipment.
The system incorporates robust protection schemes, including Mesh Protection and restoration (ASON), to ensure network resilience. It also supports various protection protocols like SNCP, MSP, and RPR, providing carrier-class reliability for critical services.
Available in two models, the OSN 1500A and OSN 1500B, the platform offers scalability to accommodate growing network demands. The modular design allows for easy expansion and maintenance, optimizing operational efficiency.
The Huawei OptiX OSN 1500 is ideally suited for deployment in metropolitan area networks (MANs), serving as an access or aggregation node. Its versatility makes it applicable in various scenarios, including:
Mobile Backhaul: Supporting 3G/LTE networks by providing efficient transport solutions for mobile traffic.
Enterprise Connectivity: Delivering high-speed, reliable connections for enterprise customers requiring diverse service types.
The Huawei OptiX OSN 1500 employs a unified switching architecture, enabling it to function seamlessly in TDM, packet, or hybrid modes. This design allows for flexible deployment scenarios, including pure packet, pure TDM, or hybrid networking, facilitating smooth integration of legacy and modern services.
