Panduit F9TSR17NNSNM003 12-Fiber OS2 LC Simplex Trunk Pigtail Assembly

The Panduit F9TSR17NNSNM003 is a 12-fiber single-mode trunk pigtail assembly engineered for datacenter, telecom, and enterprise fiber installations requiring field-terminated splice connections. Each 3-meter assembly features factory-terminated LC simplex connectors on one end and unterminated 900µm tight-buffered fiber on the opposite end, enabling fusion or mechanical splicing to backbone cable in splice enclosures or fiber distribution frames. The OS2 single-mode fiber supports 10G, 40G, and 100G Ethernet applications across extended distances up to 10 km (10GBASE-LR) or 40 km (10GBASE-ER) depending on transceiver specifications. Yellow riser-rated (OFNR) jacket meets NEC Article 770 requirements for vertical shaft installations in commercial buildings. This configuration eliminates the labor and variability of field-polishing individual connectors while preserving the flexibility to splice into existing infrastructure—ideal for patching between equipment rooms, connecting to outside plant cable entries, or building out modular fiber distribution systems where pre-terminated trunk lengths don't align with as-built dimensions.

Key Features

• 12-Fiber OS2 Single-Mode Construction: 9/125µm fiber optimized for long-reach 10G/40G/100G applications with <0.35 dB/km attenuation at 1310 nm and <0.25 dB/km at 1550 nm per TIA-492CAAA specifications
• Factory-Terminated LC Simplex Connectors: Pre-polished and tested duplex LC interfaces deliver <0.25 dB insertion loss and >50 dB return loss, eliminating field-polishing variables and reducing deployment time by 60-80% versus connector installation kits
• Unterminated Splice End: 900µm color-coded tight-buffered fibers enable fusion or mechanical splicing in standard splice trays; 12-fiber color sequence follows TIA-598-C (blue, orange, green, brown, slate, white, red, black, yellow, violet, rose, aqua) for consistent polarity mapping
• Riser-Rated OFNR Jacket: Flame-retardant PVC outer jacket qualifies for vertical riser installations per NEC 770.154(A) without requiring conduit in plenum spaces when used with plenum-rated backbone cable in air-handling zones
• 3-Meter Optimized Length: 9.84-foot assembly suits equipment room patch applications, zone distribution box-to-rack connections, and splice enclosure pigtail scenarios where 1-meter lengths are too short and 5-meter runs create excess slack management issues
• Panduit Quality Assurance: Every connector end-face inspected via automated interferometry and tested for insertion loss/return loss compliance; serialized test reports available for mission-critical deployments requiring cable-plant documentation

Trunk pigtail assemblies bridge the gap between fully pre-terminated fiber systems and traditional splice-intensive installations. In environments where backbone cable enters a building as 144-fiber loose-tube outside plant cable, pigtails provide the transition interface—installers splice the outdoor cable's 250µm bare fiber to the pigtail's 900µm buffered fiber inside a splice enclosure, then route the factory-terminated LC connectors to patch panels or direct equipment connections. This hybrid approach preserves the reliability and speed of factory terminations on the active equipment side while accommodating the unpredictable cable lengths and routing constraints typical of building entry points, basement vaults, and telecom rooms fed by campus distribution systems. The 12-fiber count matches common cassette and panel configurations (six duplex LC ports), enabling clean breakouts from 24-fiber or 48-fiber backbone strands. Unlike pre-connectorized MTP/MPO trunk assemblies that require polarity-managed adapter panels, simplex LC pigtails allow per-fiber pair routing—critical when patching diverse equipment (storage arrays, spine switches, long-reach optics) that don't share common port densities or module types.

The OS2 fiber grade ensures compliance with IEEE 802.3ae (10GBASE-LR/ER), 802.3ba (40GBASE-LR4, 100GBASE-LR4), and emerging 400G standards when paired with appropriate transceivers. Measured chromatic dispersion of ≤18 ps/(nm·km) at 1550 nm supports coherent modulation formats used in 100G+ data center interconnect (DCI) applications. The factory-polished LC connectors ship with protective dust caps and maintain <0.15 dB typical insertion loss across production lots—installers can deploy without field test equipment for routine patching, relying on link budgets that assume worst-case 0.25 dB per mated pair. Return loss exceeding 50 dB minimizes back-reflection that degrades sensitive optics in BiDi and CWDM applications. Each fiber's 900µm tight buffer (versus 250µm bare fiber in loose-tube cable) provides mechanical protection during handling and simplifies splicing—the buffer strips cleanly with standard Miller strippers, and the 0.9mm diameter fits all fusion splicer v-grooves and mechanical splice index-matching gel cavities without adapter sleeves. Color-coding follows TIA-598-C across all 12 positions, enabling installers to maintain polarity through splice trays without relying on visual fiber tracing or tone generation.

Riser (OFNR) flame rating qualifies the assembly for vertical pathways between floors in commercial buildings per NEC 770.154, provided the installation does not pass through plenum air-handling spaces. When transitioning from outdoor OSP cable (typically gel-filled loose-tube) entering a building vault to indoor vertical riser pathways, installers splice the OSP cable to riser-rated pigtails inside the vault enclosure, then route the pigtail's jacketed cable through conduit or cable tray to upper-floor telecom rooms—this maintains code compliance across the environmental boundary without requiring expensive plenum-rated cable for the entire vertical run. The yellow jacket provides instant visual identification in mixed-cable environments (blue = single-mode distribution, aqua = OM3/OM4 multimode, yellow = single-mode riser) and aids troubleshooting during MAC (move-add-change) events. The 3-meter length accommodates typical equipment room layouts—sufficient reach from a wall-mounted splice enclosure to a 19-inch rack ten feet away, while avoiding the coil-management problems of 5-meter or 10-meter assemblies that create airflow obstructions and exceed minimum bend radius when dressed into overhead cable trays.

Panduit's manufacturing process includes automated connector geometry inspection (measuring apex offset, radius of curvature, and fiber height to ±0.1µm), 100% insertion-loss testing at 1310 nm and 1550 nm, and return-loss verification using OTDR techniques. This quality gate eliminates the 2-5% field-termination defect rate common with adhesive-polish workflows, where contamination, improper curing, or inconsistent polishing pressure causes high loss or failures months after installation. For deployments requiring as-built documentation (financial trading floors, healthcare imaging networks, government SCIF installations), Panduit provides serialized test data correlated to individual cable tags—installers can archive PDF reports showing measured performance per connector, satisfying audit requirements without post-installation field testing. The factory warranty covers material and workmanship defects; typical failure modes (cracked ferrules, delaminated coatings) surface within the first 90 days, well within the claim window, and Panduit's RMA process provides cross-ship replacements to minimize downtime during warranty events.
