SC/UPC-12 Core OM3 Pigtail | Multimode-Lösung für hohe Bandbreiten

Key Characteristics & Applications

Main Advantages:

• High-Speed Data Support: OM3 50/125μm laser-optimized multimode fiber enables 10 Gigabit Ethernet at lengths up to 300 meters and is the foundation for 40/100G parallel optics.

• High-Density Connectivity: The 12-fiber configuration in a single cable simplifies management for trunk connections between patch panels or to active equipment.

• Visual Channel Identification: Die aqua blue jacket (standard for OM3/OM4) allows for quick visual differentiation from single-mode (yellow) or other fiber types in complex pathways.

• Optimized for Digital Signals: UPC polish provides low insertion loss for digital systems, ensuring signal integrity in high-bandwidth applications.

Primäre Anwendungsfälle:
✔ 10G/40G/100G Data Center Interconnects
✔ High-Performance Computing Clusters
✔ Enterprise Network Backbone Riser Cabling
✔ Campus Building-to-Building Links

Technical Specifications Summary

Technical Q&A

Q1: What is the key difference between OM3 and OM4 in this application?
A1: Both are laser-optimized 50/125μm fiber. The main difference is in the effective modal bandwidth (EMB). OM4 has a higher EMB (4700 MHz·km vs. OM3’s 2000 MHz·km @ 850nm), which supports 10/40/100G Ethernet over longer distances. For most intra-building and data center links under 100 meters, OM3 provides a cost-effective solution with full performance.

Q2: Can this OM3 pigtail be used with legacy 62.5μm (OM1) equipment?
A2: It is possible but not recommended without checking. While the connectors will mate, the mismatch in core diameters (50μm vs. 62.5μm) can cause high insertion loss (typically 3-5 dB) due to the misalignment. This loss can degrade or break the optical link. Always use a 50μm pigtail with 50μm backbone cable and equipment ports.

Q3: Is OM3 fiber still relevant with the rise of single-mode for 100G/400G?
A3: Absolutely, for short-reach economics. For links within a data center hall (under 100-150m), parallel multimode optics (like QSFP-SR4) are significantly less expensive than their single-mode long-reach counterparts. OM3/OM4 cabling remains the dominant, most cost-effective physical layer for high-speed intra-facility connectivity.
