Key Considerations for Selection

• Fiber Type: Choose between multimode (OM3, OM4, OM5) or single-mode (OS2) depending on network requirements.
• Core Count: Multi-core cables range from 36 to 96 cores for high-density applications.
• Jacket Material: LSZH is preferred for indoor fire safety; PVC is common for standard indoor use.
• Riser vs Plenum: Plenum-rated cables are required for air-handling spaces; riser-rated cables are suitable for vertical shafts.
• Standards Compliance: Ensure cables meet UL, ETL, or CPR flame safety standards for indoor deployment. These manufacturers provide high-quality, reliable indoor multi-core optical cables suitable for enterprise, commercial, and industrial installations, with options for customized configurations to meet specific project needs.
