OM5 fiber optic patch cords are 50/125 µm wideband multimode fibers optimized for high-speed, multi-wavelength applications, offering backward compatibility with OM3/OM4 and future-proofing for 200/400G Ethernet networks.

Overview

OM5 fiber optic patch cords are a TIA and IEC standardized multimode fiber with a 50/125 µm core diameter, designed to support short-wave wavelength division multiplexing (SWDM) and high-bandwidth applications while remaining fully compatible with OM3 and OM4 fibers . The identifying sheath color for OM5 is aqua green, distinguishing it from OM3/OM4's aqua blue . These patch cords are primarily used for data centers, enterprise LANs, and high-speed network backbones.

Technical Specifications

• Core/Cladding Diameter: 50/125 µm
• Wavelength Support: 850 nm to 953 nm (laser-optimized) and 1300 nm for legacy compatibility
• Bandwidth: Maintains OM4-level performance in the 850–950 nm range, supporting multi-wavelength transceivers for 100G and 400G systems
• Bend Insensitivity: Designed to minimize macrobending loss, ensuring reliable performance in tight routing environments
• Standards Compliance: ISO/IEC 11801 OM5, IEC 60793-2-10 type A1a.4, TIA/EIA-492AAAE
