Panduit F91ER1NB1SNM006 OS2 LC/APC Fiber Patch 6m

Panduit F91ER1NB1SNM006 OS2 Single-Mode Fiber Optic Patch Cord

The Panduit F91ER1NB1SNM006 delivers OS2 single-mode fiber connectivity for long-haul data transmission in commercial networks, data centers, and security installations. This 6-meter patch cord runs LC Simplex to LC/APC with a 9-micron core and 1.6mm jacket diameter, optimized for vertical riser pathways where space is tight and return loss must stay below -60 dB. The APC (angled physical contact) termination on the receive end cuts back-reflection that degrades SFP+ transceivers in 10GBASE-LR links, PoE++ IP camera uplinks beyond 300 meters, and fiber-to-building-entrance handoffs. Riser-rated OFNR jacket meets NEC 770.154(A) for installation between floors without conduit, and the yellow PVC identifies single-mode cabling at a glance during MACs. Ships in cartons of 10 for multi-drop deployments.

Key Features

• OS2 single-mode fiber: 9µm core supports 10G/40G/100G Ethernet over distances to 10 km with insertion loss under 0.5 dB
• LC Simplex to LC/APC connectors: APC polish delivers ≤-60 dB return loss, preventing SFP module damage in high-bitrate links
• Riser-rated (OFNR) jacket: NEC Article 770 compliant for vertical cable trays and risers without plenum requirements
• 1.6mm diameter cable: Fits high-density patch panels, tight conduit, and cable-management arms in 1U rack spaces
• 6-meter (19.7 ft) length: Pre-terminated span for rack-to-rack connections, building-entrance handoffs, or perimeter fiber runs
• Yellow jacket color: Industry-standard single-mode identification speeds troubleshooting and prevents cross-connection with multimode infrastructure
• Panduit Opti-Core construction: Factory-polished connectors ship with end-face geometry certified to IEC 61755-3-1 and TIA-604-10-D
• EN 60332-1-2 flammability compliance: Meets European fire standards for vertical flame propagation in commercial installations

OS2 fiber is the backbone of modern IP security networks where camera counts exceed 200 devices or individual cameras sit beyond the 100-meter copper limit. The 9-micron core and 1,310/1,550 nm wavelength transmission window let you push 10GBASE-LR SFP+ modules to 10 kilometers with modal dispersion under 1 ps/nm-km—critical when aggregating PoE++ cameras on a remote switch or feeding a distributed NVR cluster across multiple buildings. The LC Simplex form factor packs 144 fibers in a 1U panel, and the 1.6mm jacket diameter leaves room for cable-management fingers even in fully populated racks. The APC polish angle (8 degrees) reflects stray light into the cladding instead of back toward the transmitter, keeping return loss below -60 dB and preventing SFP module resets that show up as camera drop-outs during peak traffic. Standard LC/UPC connections hit -40 dB return loss at best; APC gives you 20 dB more margin before coherent-detection penalties appear in 10G optics.

Riser rating (OFNR) is the floor-to-floor workhorse for vertical cable trays, IDF-to-MDF uplinks, and any pathway that penetrates fire-rated assemblies but doesn't qualify as plenum space per NEC 300.22(C). The PVC jacket self-extinguishes per UL 1666 vertical-tray flame test, and the EN 60332-1-2 certification covers European job sites where CE marking is mandatory. The yellow jacket is the universal single-mode identifier—your day-one techs won't accidentally plug a 62.5µm OM1 multimode jumper into a 10GBASE-LR SFP and burn 90 minutes troubleshooting "no link." Six meters gives you the reach for adjacent racks in a hot-aisle/cold-aisle layout, or the slack to dress cables through overhead ladder rack with service loops at both ends. Panduit ships these in cartons of 10, so you can stage a building-entrance installation with spares on hand and keep the per-port cost predictable when the MDF-to-IDF fiber count exceeds 48 strands.

LC/APC connectors are non-negotiable when your SFP inventory includes coherent optics (QSFP28, QSFP-DD) or when you're feeding DWDM mux/demux modules in a metro-E handoff. The angled polish prevents Fresnel reflection from bouncing back into the laser cavity and destabilizing the output wavelength, a failure mode that shows up as CRC errors, flapping links, or outright SFP shutdowns on 10G-and-above interfaces. Panduit factory-polishes every connector and certifies end-face geometry to IEC 61755-3-1 (fiber height, radius of curvature, apex offset under 50 µm), so you're not field-terminating and hoping for <0.3 dB insertion loss. For IP camera networks pushing PoE++ over fiber media converters beyond 300 meters, this patch cord is the last-mile link between your edge switch and the building-entrance demarcation—where a dirty connector or back-reflection event turns into a truck roll.
