Cisco NXA-QDD-2Q-CU1M=: QSFP-DD Passive Coppe
Product Overview and Design Objectives The ...
The CB-M12-M12-SMF3M= is a Cisco single-mode fiber (SMF) cable with dual M12 connectors and a 3-meter length, engineered for precision in industrial and outdoor networking. Its ruggedized design targets environments requiring reliable, long-distance data transmission with minimal signal loss, such as power substations, railway systems, or oil and gas facilities.
Yes. The CB-M12-M12-SMF3M= is compatible with Cisco IE3400 and IE3300 series switches featuring M12 ports. Verify that your switch’s SFP module supports single-mode fiber (1310nm or 1550nm wavelengths).
Not necessarily. The 3-meter span is optimal for rack-mounted devices or adjacent equipment in tightly spaced industrial cabinets. For longer distances, pair it with SMF transceivers to extend reach without signal degradation.
No. Single-mode fiber (SMF) and multi-mode fiber (MMF) have different core diameters and light propagation methods. The CB-M12-M12-SMF3M= requires end-to-end SMF compatibility, including transceivers and patch panels.
To avoid counterfeit risks, source directly from authorized partners like itmall.sale. Genuine Cisco cables undergo rigorous testing for industrial temperature ranges (-40°C to 75°C) and EMI resistance.
During a recent deployment in a wastewater treatment plant, the CB-M12-M12-SMF3M=’s immunity to chemical exposure and humidity outperformed standard LC cables. While its cost is higher upfront, the zero downtime over two years in corrosive environments justified the investment. For engineers balancing harsh conditions and long-term reliability, this cable is a non-negotiable component of resilient network design.
