​​Core Specifications of the CB-M12-M12-SMF15M=​​

The ​​CB-M12-M12-SMF15M=​​ is a Cisco QSFP+ (Quad Small Form-Factor Pluggable) transceiver optimized for ​​40Gbps single-mode fiber (SMF)​​ applications. Key technical attributes include:

• ​​40GBASE-LR4 Standard​​: Supports 40G Ethernet over single-mode fiber with 1310nm wavelength.
• ​​15-Meter Reach​​: Designed for short-distance SMF links (up to 15 meters) using duplex LC connectors.
• ​​Dual MTP/MPO-12 Interfaces​​: Enables breakout configurations for high-density spine-leaf topologies.
• ​​Low Power Draw​​: Operates at ≤1.5W, reducing energy costs in large-scale deployments.

This module is tailored for environments requiring high-speed, low-latency interconnects within confined spaces, such as hyperscale data centers.

​​Compatibility and Deployment Scenarios​​

​​Q: Which Cisco devices are compatible with the CB-M12-M12-SMF15M=?​​

• ​​Nexus 9000 Series Switches​​: Including N9K-C93180YC-FX3, N9K-C9336C-FX2, and other FX/FX2/FX3 platforms.
• ​​UCS Fabric Interconnects​​: Integrates with UCS 6454/6332 for unified compute-network connectivity.

​​Q: Where is this transceiver typically used?​​

• ​​Data Center Inter-Rack Connectivity​​: Short-reach SMF links between adjacent racks.
• ​​High-Frequency Trading (HFT)​​: Minimizes latency for algorithmic trading systems.
• ​​AI/ML Clusters​​: Supports rapid data transfer between GPU/TPU nodes.

​​Performance Advantages Over Multimode Solutions​​

• ​​Cost Efficiency​​: Eliminates the need for expensive OM3/OM4 multimode upgrades by leveraging existing SMF infrastructure.
• ​​Breakout Flexibility​​: Splits a 40G port into 4x10G links using MTP-to-LC breakout cables, preserving legacy 10G investments.
• ​​Signal Integrity​​: SMF’s lower attenuation ensures reliable performance even in electrically noisy environments.
