Panduit F91ER1NB1SNM003 3m OS2 LC/APC Simplex Patch Cord

Panduit F91ER1NB1SNM003 OS2 Single-Mode Fiber Patch Cord

The Panduit F91ER1NB1SNM003 Opti-Core fiber optic patch cord delivers OS2 single-mode connectivity for datacenter, enterprise network, and long-haul fiber installations requiring low insertion loss and minimal back reflection. This 3-meter (9.84 ft) simplex cable terminates in LC connectors — standard UPC on one end, angled APC on the other — enabling direct connection between single-mode fiber equipment, patch panels, or cross-connects where polarity and return-loss performance are critical. The 1.6mm yellow jacketed cable is riser-rated (OFNR) for vertical runs through plenum-adjacent spaces, and ships with Panduit's factory termination quality control ensuring insertion loss stays within Standard IL specification across the 1310nm and 1550nm transmission windows.

Key Features

• OS2 9/125 micron single-mode fiber for 10G/40G/100G transmission up to 10+ km
• LC Simplex to LC/APC connectors — UPC on one end, 8° angled physical contact on the other for <-60 dB return loss in APC-terminated links
• 1.6mm simplex construction — compact, flexible jacket for dense patch-panel environments and tight bend-radius routing
• Riser (OFNR) flammability rating per NEC Article 770 for vertical cable runs between floors in non-plenum spaces
• Yellow jacket color follows TIA-598-D single-mode fiber identification standard
• Standard insertion loss specification — factory-tested to ensure <0.3 dB typical IL at 1310nm/1550nm
• 3-meter length — ideal for rack-to-rack connections, equipment-to-patch-panel links, or short cross-connects in wiring closets
• Panduit Opti-Core quality —每 connector endface inspected and cleaned before packaging, serialized test data available

Single-mode OS2 fiber is the backbone of high-bandwidth, long-distance network infrastructure — supporting 10GBASE-LR, 40GBASE-LR4, 100GBASE-LR4, and coherent optical transmission over distances that crush multimode's 300-550m ceiling. The F91ER1NB1SNM003's 9-micron core and 125-micron cladding deliver the modal bandwidth and chromatic dispersion characteristics required for metro Ethernet, SAN extension, DWDM transport, and fiber-to-the-desk deployments where future-proofing matters more than first cost. The LC connector form factor — half the footprint of SC, with a familiar RJ-style latch — maximizes port density in crowded patch panels and SFP+/QSFP28 transceiver cages, while the simplex 1.6mm cable diameter enables tight-radius routing through cable managers, vertical risers, and overhead ladder rack without risking macrobend-induced attenuation.

The hybrid LC Simplex / LC-APC termination is purpose-built for installations where one end of the link requires angled physical contact to suppress back reflection — common in PON (passive optical network) architectures, analog video-over-fiber transport, high-power laser systems, and RF-over-fiber links where reflected light causes interferometric noise or oscillation in uncooled DFB laser sources. The APC connector's 8° endface angle directs reflected light into the cladding rather than back toward the source, achieving return loss below -60 dB (vs. -50 dB typical for UPC), while the standard UPC connector on the opposite end mates with legacy equipment, media converters, or patch panels that aren't APC-compatible. Installers should note that mixing UPC and APC connectors in a mated pair causes high insertion loss (>1 dB) and potential endface damage — this cable is intended for links where APC is required on one end only, such as connecting a UPC patch panel to an APC-equipped OLT, EDFA, or CATV headend.

Riser (OFNR) flammability rating meets NEC Article 770.113(B) for general-purpose cable installations in vertical shafts, riser spaces, and non-plenum areas where airflow does not contribute to fire spread. The yellow PVC jacket is tested to EN 60332-1-2 flame propagation requirements, limiting vertical flame spread to <50mm in single-cable ignition tests. For horizontal distribution in return-air plenums or air-handling spaces above drop ceilings, specify plenum-rated (OFNP) patch cords instead — riser jackets emit smoke and combustion byproducts that violate plenum fire codes. The 1.6mm outer diameter and sequential-reverse-lay strength member construction provide a minimum bend radius of 10× cable diameter (16mm or 0.63 inches) under no-load conditions, enabling routing through tight corners, cable management fingers, and horizontal managers without exceeding the ITU-T G.652.D macrobend loss limit of +0.1 dB at 1550nm for a 30mm radius.

Panduit Opti-Core patch cords ship with factory-applied dust caps, individually bagged in static-dissipative packaging, with serialized test reports certifying insertion loss, return loss, and endface geometry per IEC 61300-3-4 (IL), IEC 61300-3-6 (RL), and IEC 61300-3-35 (endface interferometry). Each connector ferrule is inspected under 400× magnification for scratches, debris, and core-cladding concentricity before final assembly, ensuring Day 1 performance that survives the 500-cycle mating durability spec without exceeding the 0.2 dB maximum change-in-IL requirement. Standard polarity (transmit-to-receive, A-to-B) eliminates the crossed-pairs confusion common in duplex MPO or MTP trunk cables — the simplex construction is inherently polarity-correct, with no keying, flipping, or conversion modules required.
