​​Core Specifications of the CBL-R1B-SD-240-D=​​

The ​​CBL-R1B-SD-240-D=​​ is a Cisco ​​OM4 multimode fiber optic cable​​ engineered for high-density, high-bandwidth data center and enterprise network deployments. Key technical attributes include:

• ​​240-Meter Reach​​: Supports 40G/100G Ethernet over OM4 fiber with a maximum distance of 240 meters.
• ​​MPO-12 Connectors​​: Features 12-fiber MTP interfaces for seamless integration with breakout configurations.
• ​​Plenum-Rated Jacket​​: Complies with CMP fire safety standards for installation in air-handling spaces.
• ​​Bend-Optimized Design​​: Minimizes signal loss in tightly routed environments.

This cable is tailored for spine-leaf architectures, storage area networks (SANs), and high-performance computing clusters requiring low-latency connectivity.

​​Compatibility and Deployment Scenarios​​

​​Q: Which Cisco devices are certified for this cable?​​

• ​​Nexus 9000 Series Switches​​: Compatible with N9K-C9336C-FX2, N9K-C93180YC-FX3, and other 40G/100G platforms.
• ​​UCS Fabric Interconnects​​: Supports UCS 6454/6332 for unified compute-network links.
• ​​MDS 9000 Series SAN Switches​​: Enables high-speed storage replication.

​​Q: Where is the CBL-R1B-SD-240-D= most effective?​​

• ​​Data Center Spine-Leaf Topologies​​: Connects spine and leaf switches with minimal cabling complexity.
• ​​AI/ML Workloads​​: Facilitates rapid data transfer between GPU/TPU nodes.
• ​​Disaster Recovery Systems​​: Ensures high-throughput replication across geographically adjacent data centers.

​​Performance Advantages Over OM3 Cables​​

• ​​Extended Reach​​: OM4 supports 40G/100G at 150% the distance of OM3, reducing infrastructure costs.
• ​​Breakout Flexibility​​: Splits 100G ports into 4x25G or 2x50G links using MTP-to-LC modules.
• ​​Future-Proofing​​: Ready for 400G-SR8 deployments with compatible transceivers.
