flexiHaul Packet xHaul Solution Networks are migrating to packet technology to enable software-centric radio access networks and functional splits.

HFR provides the new M-series intelligent Packet fronthaul platforms for 4G/5G centralized and cloud-based RAN architectures leveraging next-generation Packet RAN access technology.
The M6424 Time-Sensitive Networking (TSN) aggregation and transport switch series support interfaces for CPRI, eCPRI and Ethernet services. This temperature hardened, one rack unit solution supports 24 x multi-rate client ports at up to 25G operation for 4G, 5G and Ethernet service coexistence, along with 4x 100GbE network ports offering multiple topologies. With high precision timing, TSN offers synchronization to the cell site remote radio, while maintaining low latency variation for aggregated 4G and 5G traffic by preempting Ethernet and Internet services.

Key Benefits

    • Significantly lowers the total cost of ownership (TCO) for fronthaul service providers: 50% lower cost, 90% turn-up time savings, 75% footprint reduction, and simplified spares inventory management compared to transponder based offerings.
    • Simplifies and converges network to reduce deployment and operational costs while simultaneously supporting multiple services: 4G LTE, 5G and Ethernet services.
    • Supports 800 Gbps-scale performance by aggregating and switching radio traffic as the fronthaul links continue to scale from: 2.5G, 10G, 25G and 100G. Preemption enables the support of mixed Ethernet services along with mobile traffic.
    • Enables multiple carrier isolation using a shared infrastructure with independent carrier services and structure agnostic mapping mode for encapsulation and transport of radio traffic.
    • Provides an open, standards-based solution to normalize operations across leading 3rd party RAN suppliers – ending vendor lock-in and eliminating interoperability problems in mixed CPRI implementations.
    • Allows better utilization of deployed fiber infrastructure for remote radio head connectivity thus reducing costs and delays associated with additional fiber investments.
    • Greatly reduces footprint by blending 4G CPRI using IEEE 1914.3 RoE, 5G eCPRI, and Ethernet high speed data services over a single compact 1RU hardened TSN platform.
