Advanced multimode optical cables, including OM3, OM4, OM5, and laser-optimized fibers, are available for high-speed, short-reach applications with multiple connector options and enhanced performance features.

Types and Specifications

OM3, OM4, and OM5 multimode fibers are widely available and optimized for high-bandwidth applications. OM3 supports data rates up to 10 Gbps, while OM4 and OM5 are designed for 40–400 Gb/s Ethernet and short wavelength division multiplexing (SWDM) applications, enabling multiple wavelengths from 850 nm to 953 nm for higher throughput and longer reach . Laser-optimized fibers reduce attenuation and microbend sensitivity, ensuring reliable, low-loss connections . Construction and Features:

• Loose tube and tight-buffered designs for indoor/outdoor use
• Armored and non-armored options for mechanical protection
• Low-smoke zero-halogen (LSZH) and flame-retardant jackets for safety in building installations
• Temperature ranges from -40°C to 85°C depending on cable type
• High fiber counts available, from 4 up to 864 fibers in dual-rated cables

Performance Advantages

• High bandwidth and low insertion loss for stable, high-speed data transmission
• Optimized for VCSEL-based transceivers, reducing power consumption in short-reach networks
• Backward compatibility with older multimode fibers (OM1/OM2) for seamless integration
• Enhanced durability against microbending and environmental stress, suitable for tight-bend installations

Connectivity Options

Multimode cables are available with a variety of connectors to suit different network setups:

• LC (Lucent Connector): High-density, easy handling, common in data centers
• SC (Subscriber Connector): Robust and industrial-friendly
• ST, E2000, CS, SN, MDC: Available for specialized applications
