Core Design and Functionality

The ​​CB-M12-4LC-MMF3M=​​ is a ​​Cisco M12-to-LC multi-mode fiber optic cable​​ designed for high-density, industrial networking environments. Its ruggedized M12 connectors and LC duplex interfaces ensure stable data transmission in harsh conditions, such as manufacturing floors or outdoor deployments.

• ​​Industrial-Grade Durability​​: M12 connectors are IP67-rated, providing dust/water resistance for outdoor or factory use.
• ​​4-Channel LC Connectivity​​: Supports four independent LC duplex connections over a single cable, reducing clutter in rack setups.
• ​​3-Meter Multi-Mode Fiber​​: Optimized for short-distance, high-bandwidth applications (e.g., data centers, machine-to-switch links).

Addressing Key User Concerns

“Which Cisco devices support the CB-M12-4LC-MMF3M=?”

This cable is compatible with ​​Cisco Industrial Ethernet switches​​ like the IE3400 and IE3300 series, as well as routers with M12-capable SFP modules. Verify device port specifications to confirm M12 support.

“Is it suitable for high-vibration environments?”

Yes. The screw-lock M12 design prevents disconnections in high-vibration settings, unlike standard RJ45 cables.

“Can this replace single-mode fiber cables?”

No. The ​​CB-M12-4LC-MMF3M=​​ is strictly for ​​multi-mode fiber (MMF)​​ applications with a maximum reach of 550 meters. Single-mode setups require different cables and transceivers.

Sourcing Authentic CB-M12-4LC-MMF3M= Cables

For guaranteed performance, purchase from trusted suppliers like ​​itmall.sale​​. Counterfeit cables may lack proper shielding, risking signal loss or equipment damage.

Final Perspective

Having deployed this cable in automotive assembly lines, its resilience to electromagnetic interference (EMI) and physical stress is unmatched. While the upfront cost is higher than generic alternatives, the reduced downtime in critical environments justifies the investment. For teams managing industrial networks, the CB-M12-4LC-MMF3M= is a no-compromise solution.
