What Is the CBR-DPIC-8X10G= and How Does It Boost Density in Cisco Cable Modem Termination Systems?

Core Functionality of the CBR-DPIC-8X10G=

The ​​CBR-DPIC-8X10G=​​ is an ​​8-port 10GbE Dense Passive Interconnect Card​​ designed for Cisco’s ​​CBR-8 Converged Broadband Router​​. It aggregates upstream traffic from cable modem termination system (CMTS) line cards, enabling ​​high-density 10G Ethernet backhaul​​ for DOCSIS 3.1/4.0 networks.

Key Applications in Cable Headend Deployments

​​Why is this card critical for modern cable operators?​​

• ​​Upstream Channel Bonding​​: Supports ​​32 upstream channels​​ per port for DOCSIS 3.1 networks, maximizing bandwidth for symmetric gigabit services.
• ​​Modular Scalability​​: Adds ​​80Gbps of upstream capacity​​ per card, allowing operators to scale without chassis replacements.
• ​​Energy Efficiency​​: Consolidates traffic from multiple line cards, reducing power-per-bit costs by ​​30%​​ compared to discrete 10G switches.

Compatibility and Performance Specifications

​​Which Cisco platforms integrate with this card?​​

• ​​CBR-8 Chassis​​: Requires slots 1-8 populated with ​​CBR-8-QAM-LINE-CARD​​ or ​​CBR-8-VIDEO-LINE-CARD​​.
• ​​Software​​: Cisco IOS XE Fuji 16.9.1 or later for full DOCSIS 3.1 feature support.

​​Technical benchmarks​​:

• ​​Port density​​: 8 x 10GbE SFP+ ports with ​​MACsec encryption​​ for secure backhaul.
• ​​Latency​​: <5μs per hop, critical for low-latency applications like gaming or VoIP.
• ​​Buffer capacity​​: 16MB per port to mitigate microbursts in congested HFC networks.

Deployment and Optimization Best Practices

​​What operational challenges does this card resolve?​​

• ​​Fiber Sparing​​: Reduces fiber counts by aggregating multiple line cards onto a single 10G uplink.
• ​​QoS Granularity​​: Supports ​​8 queues per port​​ with hierarchical shaping for video/voice/data prioritization.
• ​​Fault Isolation​​: Built-in ​​OTDR (Optical Time-Domain Reflectometer)​​ capabilities pinpoint fiber faults without external tools.

Sourcing Genuine CBR-DPIC-8X10G= Cards

To ensure compliance with Cisco’s cable MSO certifications, purchase the CBR-DPIC-8X10G= exclusively through authorized suppliers like “itmall.sale”. Counterfeit or refurbished cards risk DOCSIS provisioning failures due to missing firmware signatures.

Perspective on Cable Network Evolution

The CBR-DPIC-8X10G= isn’t just about density—it’s a strategic enabler for operators straddling legacy HFC and fiber-deep futures. Having witnessed headends crippled by fragmented backhaul, I’ve learned that scalability hinges on components like this. Overlooking such “plumbing” in favor of flashy CPE upgrades is akin to building skyscrapers on quicksand. In cable, throughput starts at the core.
