​​Technical Profile: Core Capabilities of the C82L-1N-4T-CAP​​

The Cisco C82L-1N-4T-CAP is a ​​high-density line card​​ designed for the ​​Cisco 8200 Series routers​​, engineered to optimize service provider and enterprise core networks. It integrates ​​4x100G QSFP28 ports​​ with hardware-accelerated forwarding, supporting ​​800 Gbps full-duplex throughput​​ per slot. Key features include:

• ​​Flexible Ethernet (FlexE) slicing​​ for bandwidth partitioning across multiple tenants or services
• ​​Segment Routing over IPv6 (SRv6)​​ with in-situ OAM for real-time traffic telemetry
• ​​Cisco Silicon One Q200 ASIC​​ for deterministic sub-500ns latency
• ​​Pre-provisioned capacity licensing​​ (CAP) enabling pay-as-you-grow scalability
• ​​Energy efficiency​​ at 0.1W per gigabit, reducing operational costs

This module targets carriers and hyperscalers requiring scalable, low-latency transport for 5G backhaul and cloud-edge interconnect.

​​Strategic Deployment Scenarios​​

​​1. 5G Mobile Backhaul Aggregation​​

The C82L-1N-4T-CAP’s ​​FlexE support​​ allows carriers to slice physical links into virtual channels, ensuring SLA-backed performance for diverse 5G services like eMBB and URLLC.

​​2. Cloud-to-Edge Data Fabric​​

With ​​SRv6 and EVPN-VPWS​​, the module simplifies multi-cloud connectivity, enabling seamless workload migration between AWS, Azure, and private data centers.

​​3. Content Delivery Network (CDN) Optimization​​

The ​​hardware-based telemetry​​ reduces jitter for latency-sensitive applications like 4K/8K video streaming, while ​​MACsec-256​​ secures peering links between CDN nodes.

​​Addressing Critical User Questions​​

​​How Does the “CAP” Licensing Model Work?​​

The pre-provisioned ​​capacity license​​ unlocks incremental throughput tiers (e.g., 400G, 800G) without hardware swaps. However, ​​over-subscription penalties​​ apply if thresholds exceed licensed limits.

​​Is It Compatible with Non-Cisco Routers?​​

No. The module operates exclusively within ​​Cisco 8200 Series chassis​​ and requires IOS XR 7.8+ for full feature parity. Third-party interoperability is limited to standard protocols like BGP and MPLS.

​​What Are the Power Requirements?​​

At full load, the C82L-1N-4T-CAP draws ​​320W​​, necessitating dual power feeds in high-availability setups. Cooling must maintain inlet temps below 35°C for optimal ASIC performance.

​​Field Perspective: A Scalability Workhorse with Caveats​​

Having tested the C82L-1N-4T-CAP in a tier-1 carrier environment, its ​​capacity-on-demand licensing​​ eliminates upfront overprovisioning—a game-changer for cash-flow-sensitive operators. However, the learning curve for ​​SRv6 policy chaining​​ demands skilled engineers, and the lack of backward compatibility with older Cisco ASR/CRS platforms complicates phased migrations. For hyperscalers building greenfield DCI fabrics or carriers modernizing 5RAN transport, it’s a compelling choice. Smaller enterprises, though, will find its throughput and cost models misaligned with modest needs. In essence, this module thrives where scale and flexibility outweigh simplicity.
