​What Is the CB-M12-2CS-SMF5M= Cable?​

The ​​CB-M12-2CS-SMF5M=​​ is a ​​5-meter single-mode fiber (SMF) cable​​ designed for rugged industrial and outdoor deployments. It features ​​M12-2CS (D-coded) connectors​​ on both ends, combining the precision of single-mode optics with the durability required for manufacturing floors, transportation systems, or extreme-temperature environments.


​Key Technical Specifications​

  • ​Fiber Type​​: ​​OS2 single-mode​​ (9/125µm), optimized for 1310/1550nm wavelengths.
  • ​Connectors​​: ​​M12-2CS (D-coded)​​, IP67-rated for dust/water resistance.
  • ​Max Distance​​: ​​10km at 10G (10GBase-LR)​​ with Cisco industrial switches (e.g., IE 3400 series).
  • ​Temperature Range​​: ​​-40°C to 75°C (-40°F to 167°F)​​, suitable for unheated warehouses or solar farms.
  • ​Shielding​​: Stainless steel braid + PVC jacket for crush/chemical resistance.

​CB-M12-2CS-SMF5M= vs. Standard SMF Cables: Industrial-Grade Advantages​

​Feature​ CB-M12-2CS-SMF5M= Standard LC-LC SMF Cable
​Connector Type​ M12-2CS (IP67, screw-lock) LC duplex (no environmental sealing)
​Durability​ Vibration-resistant, crush-proof Fragile in high-stress settings
​Use Case​ Robotics, rail systems, oil/gas Data center core links
​Maintenance​ 500K+ mating cycles 1K cycles (typical LC)

​Why 5 Meters and M12-2CS Matter in Industrial Deployments​

  1. ​Precision in Motion​​: The M12 screw-lock mechanism prevents disconnections in vibrating machinery (e.g., CNC machines or conveyor belts).
  2. ​Space Constraints​​: 5M length avoids excess slack in compact industrial control panels while allowing flexibility for equipment repositioning.
  3. ​EMI Immunity​​: Single-mode fiber’s immunity to electromagnetic interference ensures stable data transmission near high-voltage motors or transformers.

​Lessons from the Field​

During a wind farm project in Scandinavia, standard LC cables failed within weeks due to ice buildup and turbine vibrations. Switching to the CB-M12-2CS-SMF5M= eliminated downtime—its IP67 rating and M12 locks withstood -30°C conditions. One caveat: Always use fiber optic grease on M12 threads in subzero environments to prevent seizing. While industrial-grade cables cost 2–3x more upfront, their lifespan in harsh settings justifies the investment. In heavy industry, reliability isn’t optional—it’s the foundation of operational continuity.
