Core Specifications of the CBR-8D31-16U31-SP=
The CBR-8D31-16U31-SP= is a Cisco breakout cable designed for high-density, high-speed data center environments. Key technical attributes include:
- 400G to 8x50G Breakout: Splits a single 400G port into eight independent 50G channels using MPO-32 connectors.
- OS2 Single-Mode Fiber: Supports distances up to 2 kilometers for long-haul data center interconnects (DCIs).
- Low Insertion Loss: <0.3 dB ensures minimal signal degradation over extended runs.
- Plenum-Rated Jacket: Complies with CMP fire safety standards for installation in air-handling spaces.
This cable is engineered for hyperscale data centers and service providers requiring scalable, high-bandwidth connectivity.
Compatibility and Use Cases
Q: Which Cisco platforms support this cable?
- Nexus 9000 Series Switches: Compatible with N9K-X9736C-FX and other 400G-enabled models.
- Cisco 8000 Series Routers: Integrates with 8200/8600 platforms for carrier-grade DCIs.
- UCS X-Series Modular Systems: Supports high-performance compute-to-network links.
Q: Where is this cable most effective?
- Cloud Provider Backbones: Connects distributed data centers with high-throughput, low-latency links.
- AI Training Clusters: Enables rapid data transfer between GPU/TPU racks.
- 5G Core Networks: Supports high-capacity fronthaul/backhaul traffic aggregation.
Performance Advantages Over Direct Attach Cables
- Extended Reach: 2 km capability eliminates the need for signal boosters in metro-area DCIs.
- Future-Proof Density: 400G-to-8x50G breakout maximizes port utilization in spine-leaf architectures.
- Cost Efficiency: Reduces cabling complexity and cost per gigabit compared to multiple 50G transceivers.
