Panduit FX2ERLNLNSNF003 OM3 ST Fiber Cable 3m

Panduit FX2ERLNLNSNF003 QuickNet OM3 ST Fiber Cable

The Panduit FX2ERLNLNSNF003 is a factory-terminated 2-fiber OM3 multimode cable engineered for high-speed data center and telecom room deployments where 10GbE over multimode fiber is required. This 3-meter QuickNet assembly features dual ST connectors on both ends with standard polarity and PC (physical contact) polish, eliminating field termination labor while ensuring consistent insertion loss performance. The 1.6mm tight-buffered construction provides durability in patch panel and equipment rack environments, and full TIA-568.3-D compliance ensures interoperability with structured cabling infrastructure across enterprise and colocation facilities.

Key Features

• OM3 50/125µm multimode fiber supports 10GBASE-SR up to 300 meters and 40/100GbE at shorter distances
• Factory-terminated ST connectors on both ends with standard polarity eliminate field splicing and reduce deployment time
• PC polish on all connector endfaces minimizes back reflection and insertion loss for reliable optical performance
• 1.6mm tight-buffered cable design withstands repeated flexing in rack and cabinet routing applications
• QuickNet pre-terminated assembly ships ready to install with test results and polarity documentation
• TIA-568.3-D, ISO/IEC 11801, and ANSI/TIA-942-B compliant for standards-based data center infrastructure

ST connectors remain widely deployed in legacy fiber installations and in applications where the bayonet-style coupling provides positive retention without the risk of accidental disconnect. While LC and MPO have become dominant in new greenfield data centers, ST maintains a significant installed base in enterprise telecom rooms, government facilities, and industrial environments where equipment refreshes favor backward compatibility. This 2-fiber assembly supports full-duplex 10GbE links between switches, servers, and storage arrays, and the OM3 fiber grade ensures adequate bandwidth margin for future migration to 25GbE optics over the same infrastructure.

The 1.6mm cable diameter strikes a balance between flexibility and mechanical protection—small enough for dense patch panel routing, robust enough to survive repeated handling during MAC (moves, adds, changes) operations. The tight-buffered construction isolates each fiber in a protective polymer layer that absorbs stress during cable flexing, preventing microbend-induced attenuation that can degrade links over time. Factory termination with PC polish ensures endface geometry meets the IEC 61300-3-1 interferometric standard, and each connector is individually tested for insertion loss and return loss before shipment. Polarity follows the TIA-568 standard method, simplifying trunk and harness installations where consistent A-to-B mapping is required across multiple cable runs.

QuickNet assemblies are built on Panduit's controlled manufacturing process, which includes automated cleaving, epoxy-less mechanical termination, and multi-point optical verification. This eliminates the variability inherent in field terminations performed with hand tools under installation site conditions—critical when link budgets are tight or when deploying 10GbE over the full 300-meter OM3 distance. The 3-meter length suits short equipment-to-panel jumpers in top-of-rack switching configurations, patch panel cross-connects, and appliance interconnects where excess cable slack would create congestion in horizontal cable managers. For structured cabling professionals managing multi-vendor environments, factory-terminated assemblies reduce the risk of installer error, lower labor costs, and accelerate project handoff timelines.

Compliant with TIA-568.3-D for commercial building telecommunications cabling and ANSI/TIA-942-B for data center infrastructure, this assembly integrates into standards-based designs without compatibility concerns. The OM3 fiber grade is optimized for 850nm VCSEL transceivers common in 10GBASE-SR and 40GBASE-SR4 deployments, delivering the modal bandwidth required for error-free transmission at these speeds. ST's bayonet coupling provides tactile confirmation of full seating—a benefit in low-light rack environments—and the spring-loaded design maintains endface contact pressure over temperature cycling and mechanical vibration.
