Panduit NKFP91BN1NKM002 NetKey OS2 Single-Mode LC Pigtail Set

The Panduit NKFP91BN1NKM002 is a factory-terminated 12-fiber OS2 pigtail assembly designed for fusion-splice termination in high-density fiber distribution frames, data center entrance facilities, and telecom room cross-connects. Each 2-meter pigtail features a precision-polished LC simplex connector on one end and 900µm color-coded buffered fiber on the splice end, enabling rapid field termination of 12-fiber trunk cables without the cost and complexity of on-site connector polishing. The yellow outer jacket identifies single-mode OS2 fiber per TIA-598-D standards, and the 12-color pigtail array follows industry-standard color coding for quick visual identification during splicing and troubleshooting.

Key Features

• OS2 single-mode 9/125µm fiber rated for 10G/40G/100G Ethernet and long-haul telecom applications up to 10 km and beyond
• Factory-terminated LC simplex connectors with ceramic ferrules and sub-0.2 dB insertion loss for reliable optical performance
• 12-color pigtail set with 900µm tight-buffered fiber on splice end—blue, orange, green, brown, slate, white, red, black, yellow, violet, rose, aqua per TIA-598-C
• 2-meter (6.5 ft) length provides working slack for fusion splice enclosures and fiber management in standard 19" racks or wall-mount housings
• Yellow LSZH outer jacket for single-mode identification and plenum-rated installations in air-handling spaces
• Panduit NetKey system compatibility—mates with NetKey cassettes, panels, and enclosures for integrated infrastructure

Fusion-splice pigtails are the preferred termination method in data centers, central offices, and enterprise telecom rooms where trunk cables must be broken out to individual connectors for cross-connect flexibility. The NKFP91BN1NKM002 eliminates the need for field-polishing LC connectors—a time-intensive process requiring precision tooling, consumables, and certification. Instead, technicians fusion-splice the 900µm buffered fiber to incoming trunk cable fibers inside a splice enclosure, then route the factory-terminated LC connectors to patch panels or cassette modules. This approach delivers lower insertion loss (typically 0.1–0.3 dB per splice vs. 0.3–0.5 dB for field-polished connectors), higher return loss, and greater consistency across multi-fiber deployments. The 12-fiber count aligns with standard MPO trunk breakouts and duplex transceiver counts in 6-duplex or 12-simplex configurations, making this pigtail set ideal for 10GBASE-LR, 40GBASE-LR4, and 100GBASE-LR4 switch uplinks. The 2-meter length provides sufficient slack for splice enclosure mounting and fiber management within a rack or cabinet, while remaining short enough to avoid excess coiling that can increase attenuation or risk damage.

OS2 single-mode fiber supports transmission distances up to 10 km at 10 Gbps, 40 km at 40 Gbps with appropriate optics, and is the required fiber type for data center interconnect (DCI), campus backbone, and telecom carrier hand-off applications. The 9µm core diameter and 125µm cladding meet ITU-T G.652.D specifications, ensuring compatibility with all single-mode SFP+, QSFP+, and QSFP28 transceiver modules from Cisco, Arista, Juniper, Dell, HPE, and other OEMs. The tight-buffered 900µm construction provides mechanical protection during handling and splicing—critical in field environments where bare 250µm fiber is vulnerable to breakage—and the color-coded buffer tubes eliminate guesswork during multi-fiber splice projects. Panduit's factory termination process includes end-face inspection and cleaning per IEC 61300-3-35, so connectors arrive ready for immediate deployment without additional polishing or testing. Each LC connector is individually tested for insertion loss, return loss, and end-face geometry, and ships with a protective dust cap to prevent contamination during storage and installation.

The NetKey system architecture is widely deployed in commercial security, enterprise data center, and government installations where standards-compliant structured cabling is required for warranty coverage, building code approval, and long-term serviceability. This pigtail set integrates with NetKey fiber enclosures, cassette modules, and patch panels, enabling a unified Bill of Materials and consistent installation procedures across multi-building campuses. The yellow jacket meets NEC Article 770 plenum (OFNP) ratings for installation in air-handling spaces without conduit, and the LSZH (Low Smoke Zero Halogen) material composition complies with IEC 60754 and IEC 61034 for international deployments and high-occupancy facilities. For integrators managing data center migrations, fiber-to-the-desk rollouts, or central office upgrades, the NKFP91BN1NKM002 reduces labor cost per termination by 40–60% compared to field-polished connectors, while delivering superior optical performance and field reliability. Sold as a 12-piece pigtail set in a single package, with 20 sets per carton for project-scale procurement.
