Panduit F91EL3NB1SNM030 OS2 Single-Mode Fiber Optic Patch Cord

The Panduit F91EL3NB1SNM030 delivers OS2-rated single-mode fiber connectivity between SC and LC/APC terminations across 30 meters—a common distance for floor-to-IDF or cross-connect runs in commercial and data center deployments. The APC (Angled Physical Contact) polish on the LC end provides the low return loss required for 10GBASE-LR, 40G, 100G, and DWDM systems, while the SC simplex interface supports legacy backbone equipment or structured-cabling patch panels. The LSZH jacket meets EN 60332-1-2 for enclosed-space installations and European fire-safety mandates.

Key Features

OS2 9/125 μm single-mode fiber rated for distances up to 10 km at 10 Gbps, 40 km at 1 Gbps

SC simplex to LC simplex APC terminations—APC's 8° endface angle reduces return loss below -60 dB for high-speed and DWDM applications

LSZH (Low Smoke Zero Halogen) jacket compliant with EN 60332-1-2 for plenum-alternative installations in Europe and enclosed vertical risers

1.6 mm simplex cable diameter—35% smaller than 2 mm duplex cordage, conserving space in high-density patch fields

30-meter length suits typical floor-to-IDF, IDF-to-IDF, or horizontal cross-connect runs in multi-story commercial buildings

Yellow jacket color per TIA-598-C industry standard for single-mode fiber identification

Part of Panduit Opti-Core® fiber system with guaranteed insertion loss and batch-tested performance

Single-mode OS2 fiber operates at 9 μm core diameter, supporting laser-based transceivers across distances that multimode OM3/OM4 cannot reach. At 10GBASE-LR wavelengths (1310 nm), OS2 cable extends to 10 kilometers; at 1000BASE-LX, up to 40 kilometers. This makes the F91EL3NB1SNM030 the correct choice for campus backbone links, building-to-building interconnects, or any scenario where you need to future-proof for 40G/100G upgrades without re-cabling. The SC connector on one end matches the installed base of legacy patch panels and backbone infrastructure, while the LC connector on the opposite end interfaces with modern SFP+ and QSFP28 transceiver modules in switches, routers, and media converters.

The LC/APC termination—distinguished by its green boot and 8° angled endface—delivers return loss below -60 dB, compared to -50 dB for flat UPC polish. That 10 dB improvement matters in two scenarios: high-speed 10G+ links, where reflected energy can disrupt forward error correction and raise bit-error rates, and DWDM (Dense Wavelength Division Multiplexing) systems, where even minor back-reflection contaminates adjacent wavelength channels. If your deployment includes 10GBASE-LR SFP+ modules, 40GBASE-LR4 QSFP+, or CWDM/DWDM mux/demux equipment, APC polish is the engineered requirement. The SC end uses standard PC (Physical Contact) polish, which is sufficient for the lower-speed or backbone side of the link.

The LSZH jacket compound produces minimal smoke and zero halogen gas when exposed to flame, meeting EN 60332-1-2 vertical flame-spread requirements. While not a direct substitute for plenum-rated (CMP/OFNP) cable under U.S. National Electrical Code, LSZH is the de facto standard in Europe, Asia, and any installation governed by IEC or CENELEC fire-safety rules. It is also specified for enclosed vertical risers, telecommunication rooms, and data halls where smoke evacuation is limited. The yellow jacket color follows TIA-598-C single-mode identification conventions, preventing accidental cross-connection with aqua (OM3), magenta (OM4), or orange (OM2) multimode cordage during maintenance.

At 1.6 mm diameter, this simplex cable occupies less space than 2.0 mm duplex zip-cord, which is critical in high-density patch fields where every square inch of cable-management runway counts. The 30-meter length is a practical match for common commercial-building dimensions: a 20-meter horizontal run plus 10 meters of vertical drop and service loop, or a floor-to-floor IDF interconnect in a building with 12-foot ceilings. Panduit's Opti-Core® manufacturing process includes automated endface inspection, batch insertion-loss testing, and serialized quality tracking, ensuring that each cord meets the guaranteed maximum insertion loss of 0.5 dB (standard IL grade). This cord ships as a single unit; carton quantity is 10 for volume orders.
