Om3 Single-film optical fiber

OM3 is a laser-optimized multimode fiber (LO-MMF) with a 50 µm core, designed for high-speed Ethernet applications up to 100G over short distances. Key Characteristics of OM3 FiberCore Diameter: 50 micrometers, smaller than OM1 (62. 5 µm) but optimized for laser sources like VCSELs.

Modal Bandwidth: 2000 MHz·km at 850 nm wavelength, allowing high-speed data transmission. Jacket Color: Aqua, standard for OM3 multimode fiber. Light Source Compatibility: Optimized for vertical-cavity surface-emitting lasers (VCSELs), which are cost-effective and energy-efficient.

Performance and ApplicationsOM3 fiber is widely used in enterprise LANs, data centers, and short-range high-speed networks. Its performance supports: 10G Ethernet: Up to 300 meters25G Ethernet: Up to 70 meters40G/100G Ethernet: Up to 100 meters OM3 is backward compatible with OM2 fiber but offers significantly higher bandwidth and longer reach for laser-based applications. It is ideal for inter-rack connections, server-to-switch links, and high-density data center environments.

Comparison with Other Multimode FibersOM1: 62. 5 µm core, LED-based, supports 10G Ethernet only up to 33 meters. OM2: 50 µm core, LED-based, supports 10G Ethernet up to 82 meters.

OM4: 50 µm core, higher modal bandwidth (4700 MHz·km), supports 10G up to 550 meters and 40G/100G up to 150 meters. OM5: Wideband multimode fiber (WB-MMF), supports multiple WDM channels for future-proof high-density applications. SummaryOM3 single-film optical fiber is a cost-effective, high-performance multimode fiber optimized for laser-based transceivers, making it suitable for modern data centers and enterprise networks requiring 10G to 100G Ethernet over short distances.

Its combination of 50 µm core, 2000 MHz·km bandwidth, and VCSEL compatibility ensures reliable, high-speed connectivity while remaining compatible with existing multimode infrastructure.
