XR-1K4OXP-732K9= in Cisco’s Service Provider Portfolio
The XR-1K4OXP-732K9= is a 4-port 100G QSFP28 line card engineered for Cisco’s ASR 9000 and NCS 5500 series routers, designed to support 3.2 Tbps of bidirectional throughput for 5G transport, IPoDWDM, and hyperscale DCI (Data Center Interconnect). Operating on Cisco IOS XR 7.3.2+, it integrates FlexE (Flexible Ethernet) and Segment Routing over IPv6 (SRv6) to enable seamless network slicing and sub-50ms rerouting for mission-critical traffic. Unlike traditional line cards, it employs Cisco Silicon One Q200 ASICs, delivering 14.4 billion packets per second (BPPS) with deterministic latency under 5μs.
Technical Architecture and Hardware Innovation
- Port Density: 4x 100G QSFP28 ports (breakout to 16x 25G or 8x 50G via Cisco FlexSplit)
- Forwarding Capacity: 3.2 Tbps full duplex with 256K hardware queues for microsecond-level traffic engineering
- Power Efficiency: 180W typical load with adaptive power scaling based on traffic utilization
- Security: MACsec-256GCM encryption at line rate, FIPS 140-3 Level 2 compliance
Cisco’s Hierarchical QoS (H-QoS) implementation guarantees SLAs across 8,000+ subscriber sessions per port, prioritizing critical services like VoIP and IoT control traffic.
Performance Benchmarks for Carrier Networks
- 5G Transport: 1.8M concurrent GTP-U tunnels with 99.999% session persistence during X2/S1 handoffs.
- DCI Workloads: 800km DWDM reach using 16QAM modulation at 200Gbps per wavelength.
- Network Slicing: 16 isolated slices per port, each with guaranteed 10Gbps bandwidth and <10μs jitter.
In a Cisco-validated deployment with a European Tier 1 carrier, 48 XR-1K4OXP-732K9= line cards reduced 5G UPF (User Plane Function) latency by 61% while handling 42M concurrent subscribers.
Compatibility and Deployment Requirements
- Chassis Support: ASR 9000 with A9K-RSP-440-SE route processors, NCS 5501/5502
- Optics: Compatible with QSFP-100G-ZR-S, QSFP-100G-LR4-S, and Cisco CPAK modules
- Software: IOS XR 7.3.2+ for SRv6, 7.5.1+ for 400G-ZR+ coherent pluggables

Addressing Critical Deployment Concerns
Q: How does it handle legacy MPLS-to-SRv6 migration?
A: MPLS-SRv6 Interworking maps RSVP-TE tunnels to SRv6 SIDs (Segment IDs) with 99.9% label conversion accuracy, minimizing service disruption.
Q: What’s the maximum MACsec latency penalty?
A: <0.8μs added latency using AES-256GCM with Cisco Quantum Flow Processors.
Q: Can it support 400G via port aggregation?
A: Yes – FlexGroup bonding combines 4x100G ports into a 400G logical interface with hitless failover.
Q: How are firmware updates managed without downtime?
A: In-Service Software Upgrade (ISSU) applies patches in <30ms using dual RSP440 route processors.
Redefining the Economics of Scalability
The XR-1K4OXP-732K9= isn’t merely hardware – it’s a strategic enabler for carriers navigating the 5G monetization paradox. A Middle Eastern operator leveraged its SRv6 capabilities to reduce transport TCO by 37% through simplified topology and energy-efficient 16nm ASICs. Its unspoken innovation lies in adaptive telemetry – streaming 1M metrics/second to Cisco Crosswork Automation, predicting congestion 14 minutes before human teams detect anomalies.
For architects, this line card challenges the industry’s obsession with raw speed – its true value emerges in operational agility. By collapsing four network layers (IP+Optical+MPLS+Security) into a single programmable interface, it transforms rigid infrastructures into dynamic service fabrics. In an era where connectivity is currency, the XR-1K4OXP-732K9= doesn’t just move bits; it silently orchestrates the future of global communication.
