Panduit F91ER3NB1SNM015 Opti-Core OS2 Single-Mode Fiber Patch Cord
The Panduit F91ER3NB1SNM015 is a 15-meter OS2 single-mode fiber optic patch cord engineered for high-bandwidth, low-loss connectivity in structured cabling and data center installations. Featuring an SC simplex connector on one end and an LC/APC simplex connector on the other, this asymmetric jumper bridges equipment with different interface standards while maintaining the signal integrity required for 10GbE, 40GbE, and 100GbE networks. The 1.6mm riser-rated (OFNR) cable is designed for vertical building runs and complies with fire-safety codes for in-plenum and riser pathways.
Key Features
- OS2 single-mode fiber (9/125μm) supports distances up to 10 km at 10 Gb/s and beyond
- SC to LC/APC asymmetric configuration adapts legacy SC ports to modern LC infrastructure
- APC (Angled Physical Contact) polish on LC end reduces back reflection below -60 dB for low-noise links
- 1.6mm simplex cable design minimizes pathway congestion in high-density racks
- Riser (OFNR) flame rating meets NEC Article 770 for vertical building installations
- Standard insertion loss specification ensures predictable link budgets in multi-span networks
- 15-meter (49.2 ft) length ideal for cross-rack connections, IDF-to-equipment runs, or floor-to-floor links
- Yellow jacket provides instant OS2 single-mode identification per TIA-598-D color coding
- Opti-Core sub-brand signifies Panduit's factory-terminated, tested jumper program
OS2 single-mode fiber delivers the lowest attenuation and highest bandwidth of any fiber type, making it the default choice for 10GBASE-LR, 40GBASE-LR4, 100GBASE-LR4, and next-generation 400G optics. The 9μm core diameter and 125μm cladding support laser-optimized transmission over distances that far exceed multimode fiber capabilities, with typical attenuation at 1310 nm below 0.4 dB/km and at 1550 nm below 0.3 dB/km. The F91ER3NB1SNM015's SC-to-LC/APC configuration is particularly useful in migration scenarios where you're connecting older SC-based switches or media converters to newer LC-based SFP+ or QSFP28 modules. The APC polish on the LC end—ground at an 8-degree angle—ensures physical contact occurs on a slant, directing any reflected light into the cladding rather than back toward the source. This is critical in analog video transport, high-speed coherent optics, and any application where return loss below -60 dB is required. The SC end uses standard UPC (Ultra Physical Contact) polish, which is the norm for SC connectors and delivers return loss better than -50 dB. Standard insertion loss on this patch cord is factory-verified to remain below the 0.75 dB maximum specified in TIA-568.3-D, giving you margin to spare in most link budgets. Panduit's Opti-Core factory-termination process uses automated polishing and inspection to ensure consistent endface geometry, eliminating the variability and contamination risks of field terminations.
The 1.6mm cable diameter makes the F91ER3NB1SNM015 well-suited for dense patch-panel environments where every millimeter of pathway space counts. In a 1U horizontal cable manager, you can route dozens of these simplex jumpers without exceeding bend-radius limits or blocking airflow. The riser (OFNR) jacket rating means the cable meets UL 1666 flame-propagation requirements and can be installed in vertical shafts, risers, and ducts without requiring additional conduit in most jurisdictions. For plenum spaces, you'll need an OFNP-rated variant; for general-purpose non-riser horizontal runs, OFNR provides more than adequate fire safety. The 15-meter length falls into the sweet spot for intra-building connections: long enough to span multiple racks, cross a row, or connect floors in a low-rise building, yet short enough to avoid the excess coiling and loss budget waste that comes with over-provisioned jumpers. When planning your fiber infrastructure, remember that every connector interface introduces approximately 0.3–0.75 dB of insertion loss, and every fusion splice adds 0.05–0.1 dB; with OS2 fiber's inherent low attenuation, your link budget is dominated by connector loss rather than fiber loss, so choosing factory-terminated jumpers with verified IL specs directly impacts network reliability.
This patch cord meets EN 60332-1-2 for flame propagation and ships in cartons of 10, making it cost-effective for staging bulk deployments or maintaining spares inventory. The yellow jacket conforms to TIA-598-D color-coding standards, which specify yellow for single-mode fiber to prevent accidental cross-connection with orange (OM1/OM2), aqua (OM3/OM4), or lime (OM5) multimode cables—a mix-up that would result in complete link failure due to mode-field diameter mismatch. For integrators managing mixed-mode networks, the color and labeling discipline provided by Panduit's Opti-Core line reduces troubleshooting time and prevents costly mis-patches during MACs (Moves, Adds, Changes). Whether you're building out a new data center, upgrading legacy SC infrastructure to LC, or extending single-mode links in a campus backbone, the F91ER3NB1SNM015 delivers the performance, compliance, and factory-verified quality that enterprise and service-provider networks demand.
