هواوي OSN7500 SDH
وصف
نظرة عامة على المنتج
The Huawei OSN7500 SDH isn’t just an SDH platform—it’s the beating heart of next-generation optical intelligence. Engineered for telecom giants, smart cities, and mission-critical networks, this flagship multi-service transport platform converges TDM, Ethernet, and packet services onto a single unified architecture. With 360G high-order TDM switchingو 160G packet capacity, it delivers uncompromised density for 5G backhaul, financial cores, and broadcast streams—all while slashing operational costs by 40%. Whether you’re scaling metropolitan backbones or bridging rural digital divides, the OSN7500 transforms complexity into simplicity, friction into flow.
Why Operators Trust OSN7500: Unmatched Advantages
1. Unified Switching for Zero-Compromise Evolution
- TDM + Packet Fusion: Seamlessly handle legacy E1/T1 circuits alongside 10GE/OTN traffic—eliminating separate network layers.
- Future-Proof Upgrades: Transition from pure TDM to hybrid or full-packet networks via software updates, bypassing 2-3 years of hardware redesign.
2. Carrier-Grade Resilience
- Five-Nines Uptime Architecture:
- على مستوى الأجهزة: Hot-swappable cross-connect boards (SXCSA/UXCSA) with <50ms failover.
- على مستوى الشبكة: Mesh restoration with SLA-based protection (Diamond/Gold/Silver tiers).
- مستوى الخدمة: Hitless software upgrades during peak traffic.
3. Hyper-Density for Bandwidth-Intensive Scenarios
- Broadcast & 5G Ready: 48xSTM-64 ports support 4K/8K video distribution or 10K+ small-cell backhaul.
- Smart City Proven: Deployed in Jiangsu Cable TV’s backbone for 200K concurrent streams.
دليل المشتريات الاستراتيجية
لمهندسي الشبكات
- Tier-1 Carriers: Opt for SLD64 boards + SXCSA cross-connect for 360G TDM core. Pair with EGS4 for 10GE aggregation.
- Hybrid Networks: Leverage MPLS-TP licenses to unify SDH and IP domains (e.g., Vodafone Italy’s 2.1M-subscriber backbone).
للمشترين للمعدات المستعملة
