Panduit F91ELANB1SNM001 Opti-Core OS2 Single-Mode Fiber Patch Cord
The Panduit F91ELANB1SNM001 is a 1-meter OS2 single-mode fiber optic patch cord engineered for high-performance datacenter, enterprise network, and security backbone installations. Part of Panduit's Opti-Core line, this simplex cord terminates in SC APC on one end and LC/APC on the other, providing low-insertion-loss connectivity between dissimilar equipment interfaces. The 1.6 mm LSZH jacket meets EN 60332-1-2 flammability standards, making it compliant for plenum and enclosed-space deployments where smoke toxicity and flame spread are regulated. Integrators connecting single-mode transceivers, media converters, or fiber distribution panels will appreciate the factory-polished angled physical contact (APC) connectors, which deliver superior return loss and minimize back-reflection compared to standard PC or UPC terminations.
Key Features
- OS2 single-mode 9/125 μm fiber for long-distance, high-bandwidth transmission up to 10 Gbps and beyond
- SC APC to LC/APC simplex configuration bridges dissimilar port types on switches, transceivers, and patch panels
- 1.6 mm LSZH (Low Smoke Zero Halogen) jacket meets EN 60332-1-2 for safe installation in plenum and enclosed spaces
- Standard insertion loss specification ensures reliable link budgets in structured cabling and point-to-point links
- Factory-terminated APC (angled physical contact) connectors minimize back-reflection for sensitive optical equipment
- 1-meter (3.2 ft) length ideal for rack-to-rack, equipment-to-patch-panel, or short inter-building runs
- Yellow jacket color codes single-mode fiber per industry convention, simplifying field identification
- Opti-Core sub-brand signals Panduit's premium fiber product line with rigorous quality control
OS2 single-mode fiber supports transmission distances up to 10 km (10GBASE-LR) or 40 km (10GBASE-ER) depending on transceiver type, making it the standard choice for campus backbones, inter-building links, and any application where multimode's 300-meter range limit is insufficient. The 9 μm core diameter requires laser-based transceivers (1310 nm or 1550 nm wavelengths), which are now cost-competitive for even short runs in modern datacenters. APC connectors use an 8-degree angled endface polish that directs reflected light into the cladding rather than back down the core; this yields return loss better than -60 dB (vs. -50 dB for UPC), critical when connecting to DWDM systems, high-sensitivity receivers, or any link budget constrained by reflective noise. Standard insertion loss specification—typically ≤0.3 dB for factory-terminated patch cords—leaves headroom for splices, additional connectors, and aging without risking link dropout. The simplex (single-fiber) construction suits applications where transmit and receive occur on separate fibers or where bidirectional (BiDi) transceivers are deployed.
The LSZH jacket compound contains no halogens (chlorine, fluorine, bromine), so combustion produces minimal smoke opacity and zero corrosive hydrochloric acid vapor—a life-safety requirement in occupied plenums, hospitals, transportation hubs, and any installation governed by IEC 60754 or EN 60332-1-2. The 1.6 mm outer diameter balances flexibility for tight-radius bends in high-density panels with enough rigidity to prevent kinking during pulls. Yellow color coding follows TIA-598-C convention for single-mode fiber, allowing instant visual differentiation from aqua (OM3/OM4 multimode) or orange (OM1/OM2) in mixed-mode environments. One-meter length handles typical equipment-to-panel distances in 19-inch racks or small IDF closets without excess slack coiled behind equipment. SC and LC are the two most common connector types in enterprise and security infrastructure: SC (subscriber connector) remains prevalent on older switches and media converters, while LC (Lucent connector) dominates SFP/SFP+ transceiver modules. This hybrid SC-to-LC cord eliminates the need for bulkhead adapters or gender changers when interfacing legacy and modern gear.
Panduit's Opti-Core fiber line undergoes end-face geometry inspection and insertion-loss testing before shipment, ensuring each cord meets or exceeds TIA-568 and IEC 61300 specifications for concentricity, apex offset, and radius of curvature. Integrators can trust published insertion-loss values without field testing every cord, reducing commissioning time on large projects. Ships in cartons of 10 with each cord individually bagged to protect connector endfaces from contamination—use the provided dust caps until the moment of insertion, and inspect endfaces with a fiber microscope if you encounter unexpected loss or reflectance readings during acceptance testing.
