24-core single-mode fiber for indoor use

24-core single-mode fiber cables for indoor use are available in plenum, riser, and breakout designs, offering high performance, low-smoke safety, and durability for building backbones and data networks.

Key Features

Fiber Type and Performance: Most indoor 24-core cables use OS2 single-mode fibers with a 9/125µm core-to-core diameter, optimized for long-distance transmission and high bandwidth. Many utilize Corning SMF-28 Ultra fibers, supporting 1310nm and 1550nm wavelengths and ITU-T G.657.A1 compliance for backward compatibility with legacy fibers . Cable Construction:

• Tight-buffered or breakout design with 900µm fibers for easy termination and handling .
• Strength members such as aramid yarn provide tensile strength and durability during installation .
• Jacket materials include plenum-rated (low-smoke, flame-retardant) or riser-rated (CMR) PVC for indoor safety .
• Some models feature steel-armored single-tube construction for added protection in high-traffic or industrial indoor environments . Safety and Compliance:
• Plenum-rated cables are suitable for air-handling spaces, producing low smoke and non-toxic gases in case of fire .
• Riser-rated cables are designed for vertical runs in buildings, meeting UL-1666 standards for flame resistance .
• Many cables are RoHS compliant, ensuring environmental safety . Applications:
• Intra-building backbones connecting floors or departments.
• Data centers and telecommunication networks requiring high-speed, long-distance connectivity.
• Fiber rack systems and headend terminations for structured cabling . Installation Considerations:
• Tight-buffered fibers allow easy termination with LC/UPC connectors .
• Pulling strength and flexible jackets facilitate installation in conduits, risers, or plenum spaces .
• Indoor/outdoor rated cables can be used indoors with added environmental protection if needed . Examples of Available Products:
• Plenum-rated 24-strand indoor single-mode cable with aramid yarn and low-smoke jacket for multi-floor deployment .
• Breakout 24-core LC-LC single-mode cable with flexible tear-resistant nylon jacket for indoor installations .
• Indoor/outdoor riser-rated 24-strand OS2 cable with water-blocking aramid yarn and flame-retardant jacket for long-distance runs .
• Steel-armored single-tube 24-core cable for high-performance indoor networks requiring extra durability . These cables provide reliable, high-speed connectivity for indoor networks while meeting safety and installation standards, making them suitable for enterprise, data center, and multi-floor building applications.
