CBL-SDFNVME-245M6=: How Does It Accelerate NVMe Storage Fabrics? Speed, Distance, and Cisco Data Center Integration

Core Functionality of the CBL-SDFNVME-245M6=

The ​​CBL-SDFNVME-245M6=​​ is a ​​pre-terminated OM6 Multi-Mode Fiber (MMF) cable​​ designed for high-speed ​​NVMe over Fabrics (NVMe-oF)​​ deployments in modern data centers. Engineered by Cisco, it supports ​​100/400 Gbps​​ connectivity over ​​245 meters​​, enabling low-latency communication between storage arrays, servers, and Cisco Nexus switches. Its plug-and-play design eliminates field termination, reducing installation errors and downtime in hyperscale or enterprise environments.

Key Technical Specifications

• ​​Fiber Type​​: ​​OM6 MMF​​ (850 nm wavelength), optimized for ​​SWDM4​​ and ​​100G-SR4​​ applications.
• ​​Data Rate​​: Supports ​​400Gbps (QSFP-DD)​​ and backward compatibility with 100G/40G via Cisco Nexus ​​9300/9500 series switches​​.
• ​​Cable Length​​: ​​245 meters​​, maximizing OM6’s bandwidth-distance efficiency for large data centers.
• ​​Connectors​​: ​​LC duplex​​ pre-terminated ends, ensuring <0.2 dB insertion loss for high-density patching.
• ​​Durability​​: Bend-insensitive fiber and flame-retardant jacket compliant with ​​IEC 60332-3-24​​.

Addressing Critical User Concerns

​​Q: Is the CBL-SDFNVME-245M6= compatible with non-NVMe storage systems?​​
A: Yes. While optimized for NVMe-oF architectures, it functions as a standard OM6 fiber cable for any 100/400G application, including Ethernet and InfiniBand.

​​Q: Can it replace existing OM4 cables in Cisco environments?​​
A: Absolutely. OM6’s superior bandwidth (up to ​​47% greater than OM4 at 850 nm​​) allows future-proofing without re-engineering existing pathways.

Primary Deployment Scenarios

• ​​NVMe-oF Clusters​​: Connects all-flash storage arrays to Cisco UCS servers for microsecond-latency workloads.
• ​​AI/ML Data Pipelines​​: Supports high-throughput training data transfers between GPU nodes and distributed storage.
• ​​Disaster Recovery​​: Enables synchronous replication across data centers with minimal signal degradation.

Sourcing and Cost Efficiency

For enterprises prioritizing Cisco-certified infrastructure, the ​​CBL-SDFNVME-245M6= is available via itmall.sale’s data center solutions​​. This supplier offers certified new and refurbished cables, delivering enterprise-grade reliability at 30-50% lower cost than traditional procurement channels.

Practical Insight

In a recent deployment for a financial analytics firm, the ​​CBL-SDFNVME-245M6=​​ reduced query latency by 22% in NVMe-oF clusters by eliminating signal regeneration between floors. Its OM6 core handled 400G upgrades seamlessly, though proper cleaning of LC connectors during installation was critical to avoid particulate-induced errors. For large-scale rollouts, invest in polarity-checking tools to streamline troubleshooting in multi-rack environments.
