Panduit F91EL1NB1SNM007 OS2 Single-Mode Fiber Optic Patch Cord

The Panduit F91EL1NB1SNM007 is a 7-meter OS2 single-mode fiber optic patch cord engineered for datacenter, telecom, and high-bandwidth security system backbone applications requiring low insertion loss and minimal back reflection. This Opti-Core® simplex cable features LC Simplex to LC/APC (angled physical contact) connectors with 9-micron core diameter, optimized for 10G, 40G, and 100G Ethernet deployments where long-distance transmission and wavelength-division multiplexing are critical. The 1.6mm LSZH (Low Smoke Zero Halogen) jacket meets EN 60332-1-2 flammability standards, making it compliant for plenum and riser installations in healthcare, education, and commercial facilities where fire safety codes prohibit PVC. At 23 feet, this length suits mid-range rack-to-rack connections, patch-panel-to-switch links, or equipment-to-MDF runs in structured cabling systems. Panduit factory-terminates each connector and tests insertion loss to guarantee standard IL performance out of the box—no field termination, no polishing, no guesswork.

Key Features

• OS2 single-mode fiber with 9-micron core for distances up to 10 km at 10 Gbps and beyond
• LC Simplex to LC/APC connectors—angled physical contact reduces back reflection to -60 dB for DWDM and high-speed analog systems
• LSZH jacket rated EN 60332-1-2 for plenum/riser compliance in fire-sensitive environments
• 7-meter (23 ft) length bridges mid-range rack spans without excess slack or cable management bulk
• Standard insertion loss specification ensures <0.3 dB attenuation per connector pair
• 1.6mm simplex construction for tight-radius bend applications and high-density patch panels
• Panduit Opti-Core® quality—factory terminated, inspected, and individually serialized
• Yellow jacket per TIA-598-C color code for instant OS2 single-mode identification in mixed-fiber plants

Single-mode OS2 fiber delivers the bandwidth and reach that modern datacenters and security networks demand. Unlike OM3/OM4 multimode, OS2's 9-micron core supports wavelengths from 1310 nm to 1550 nm with near-zero modal dispersion, enabling 10GBASE-LR, 40GBASE-LR4, and 100GBASE-LR4 over distances that multimode cannot touch. The LC/APC connector on one end is purpose-built for applications where return loss matters—coherent optics, DWDM systems, PON networks, and RF-over-fiber links in distributed antenna systems (DAS) all benefit from the angled endface that steers reflected light into the cladding rather than back into the core. The LC Simplex connector on the opposite end mates with standard LC interfaces found on switches, media converters, and fiber NICs. This hybrid simplex-to-APC configuration is common in access-layer-to-core-layer links where one side terminates at DWDM mux/demux equipment and the other at a standard Ethernet switch.

The LSZH jacket is non-negotiable in hospitals, schools, airports, and any facility where building codes mandate low-toxicity, low-smoke cable materials. EN 60332-1-2 certification confirms the cable will self-extinguish and emit minimal smoke and no halogenated acids if exposed to flame—critical for life safety and equipment protection during fire events. The 1.6mm simplex diameter keeps cable bundle size manageable in congested pathways, and the reduced bend radius (typically 10× cable diameter, or 16 mm) allows routing through tight corners and high-density patch-panel ports without risking fiber fracture. Panduit's factory termination process uses precision ceramic ferrules, epoxy-and-polish techniques, and automated endface inspection to guarantee each connector meets IEC 61300-3-35 geometry limits for radius of curvature, apex offset, and fiber height. Standard insertion loss (<0.3 dB per mated pair) means you can cascade multiple patch cords in a channel without eating into your link budget—essential when designing 10GBASE-LR links that already operate near the -14.4 dBm receiver sensitivity threshold.

This patch cord integrates seamlessly into structured cabling systems that follow TIA-568 or ISO/IEC 11801 standards. Use it to cross-connect LC simplex ports on fiber distribution panels, bridge floor-to-floor risers in vertical campus networks, or connect IP camera NVRs and access-control panels to fiber-backbone switches in large-scale security deployments. The 7-meter length is long enough to reach across adjacent racks or span a small equipment room without requiring mid-span splices, yet short enough to avoid the signal degradation and cable-management headaches that come with oversized jumpers. Panduit backs the Opti-Core line with lot traceability, test data on file, and a manufacturing process audited to ISO 9001—giving you the documentation trail that enterprise and government contracts demand. For installations where fiber quality directly impacts uptime, choosing factory-terminated Panduit patch cords over field-terminated alternatives eliminates the top three failure modes: contaminated endfaces, improper polish angles, and out-of-spec insertion loss.
