What Is the CB-M12-M12-MMF20M=? Compatibility, Use Cases, and Sourcing Tips

​​CB-M12-M12-MMF20M= Overview and Key Specifications​​

The ​​CB-M12-M12-MMF20M=​​ is a Cisco QSFP+ (Quad Small Form-Factor Pluggable) transceiver optimized for ​​40G Ethernet​​ and ​​high-density data center deployments​​. Core technical attributes include:

• ​​40Gbps Data Rate​​: Supports 40GBASE-SR4 standards for short-range multimode fiber (MMF) connectivity.
• ​​20-Meter Reach​​: Designed for OM3/OM4 fiber with a maximum distance of 20 meters.
• ​​MTP/MPO-12 Connectors​​: Features dual 12-fiber MTP interfaces for simplified cabling in spine-leaf topologies.
• ​​Low Latency​​: Ideal for latency-sensitive applications like financial trading or real-time analytics.

This module is engineered for environments requiring high throughput within confined spaces, such as hyperscale data centers.

​​Device Compatibility and Deployment Scenarios​​

​​Q: Which Cisco platforms support the CB-M12-M12-MMF20M=?​​

• ​​Nexus 9000 Series Switches​​: Compatible with models like N9K-C93180YC-FX3 and N9K-C9336C-FX2.
• ​​UCS Fabric Interconnects​​: Integrates with UCS 6454 and UCS 6332 for unified server-to-network connectivity.

​​Q: Where is this transceiver most effective?​​

• ​​Data Center Spine-Leaf Architectures​​: Connects switches with high port density and minimal cabling complexity.
• ​​Storage Area Networks (SANs)​​: Supports high-speed backups and disaster recovery systems.
• ​​AI/ML Workloads​​: Reduces bottlenecks in GPU cluster communications.

​​Performance and Cost Efficiency​​

• ​​Breakout Flexibility​​: Splits a 40G port into 4x10G links using MTP-to-LC breakout cables, maximizing legacy infrastructure reuse.
• ​​Power Efficiency​​: Consumes under 1.5W, reducing operational costs in large deployments.
• ​​Plug-and-Play Simplicity​​: Hot-swappable design minimizes downtime during upgrades.
