Understanding the A9KV-50-FTF=
The A9KV-50-FTF= is a 50-port 10G/25G Flexible Rate Interface Module designed for Cisco’s ASR 9000 Series routers. Targeting service providers and hyperscalers, this module addresses the need for high-density, multi-service aggregation in scenarios like data center interconnect (DCI), broadband remote access server (BRAS) deployments, or 5G midhaul networks. Unlike fixed-configuration line cards, it supports mixed-speed ports (1G to 25G) and software-defined port types, enabling adaptive resource allocation.
Technical Capabilities and Innovations
- Port Density: 50x SFP28 slots with support for 1G/10G/25G optics, reducing chassis footprint by 40% compared to older modules.
- Throughput: 1.25 Tbps per slot, leveraging Cisco’s Quantum Flow Processor (QFP) for deep packet inspection and QoS enforcement.
- Energy Efficiency: 15% lower power-per-port than the A9KV-40-FTF=, achieved through dynamic power scaling based on traffic load.
- Protocols: Native integration with EVPN, MPLS-SR, and PBB-EVPN, streamlining carrier Ethernet and cloud-scale MAC mobility.
A9KV-50-FTF= vs. A9KV-40-FTF=: Key Upgrades
| Feature | A9KV-50-FTF= | A9KV-40-FTF= |
|---|---|---|
| Port Count | 50 | 40 |
| Max Speed per Port | 25G | 10G |
| Buffer Memory | 32 MB per port | 16 MB per port |
| Latency | <2 µs | <5 µs |
| Typical Use Case | 5G Midhaul/BRAS | Metro Ethernet |
This module excels in environments requiring sub-2-microsecond latency and per-flow telemetry, such as financial trading networks or real-time video backhaul.
Addressing Deployment Concerns
Is the A9KV-50-FTF= compatible with non-Cisco optics?
Only Cisco-validated or [“A9KV-50-FTF=” link to (https://itmall.sale/product-category/cisco/) optics are supported for performance guarantees. Third-party SFPs may trigger alarms or throttle speeds.
How does it handle oversubscription?
The 4:1 oversubscription ratio is managed via Hierarchical QoS (HQoS), prioritizing mission-critical traffic like VoIP or IoT control packets.
What cooling infrastructure is required?
Operates optimally at 5°C to 40°C with front-to-back airflow. Deployments in enclosed spaces require active cooling trays for sustained 25G operation.
Strategic Value in Modern Networks
The A9KV-50-FTF= isn’t just about density—it’s a capex/opex game-changer for operators drowning in fiber sprawl. While its upfront cost is steep, consolidating three legacy modules into one slashes rack rental and power costs by 50% over five years. For teams deploying vRAN or network slicing, its ability to dynamically reassign ports between services (e.g., shifting 10G mobile backhaul to 25G DCI) is indispensable. Always pair it with Cisco Crosswork Network Controller to automate service provisioning and avoid underutilization pitfalls.
