Panduit FRXTP77Y001F078 12F OM3 Trunk 78ft POLB

Panduit FRXTP77Y001F078 Opti-Core 12-Fiber OM3 Plenum Trunk Cable - 78ft

The Panduit FRXTP77Y001F078 is a factory-terminated 12-fiber OM3 multimode trunk cable designed to eliminate field termination time, testing overhead, and connector variability in mission-critical fiber deployments. This 78-foot plenum-rated trunk ships with duplex LC connectors on both ends in Type B polarity configuration, enabling immediate plug-and-play installation between patch panels, zone enclosures, or direct equipment connections. Pre-terminated at Panduit's ISO 9001-certified facilities with automated polishing and 100% insertion-loss testing, this trunk delivers guaranteed performance for 10GBASE-SR, 40GBASE-SR4, and 100GBASE-SR10 applications without the field labor, consumables, or rework risk of on-site termination.

• Ships with serialized test report documenting insertion loss, return loss, and fiber geometry per IEC 61300-3-34
• Yellow jacket color-codes OM3 fiber type per TIA-598-D for instant visual identification in mixed-mode plants

OM3 fiber is laser-optimized 50/125µm multimode fiber with 2000 MHz·km effective modal bandwidth at 850nm, purpose-built for VCSEL-based 10 Gigabit and parallel-optic 40/100 Gigabit Ethernet. Unlike OM1/OM2 LED-grade fibers, OM3's tightly controlled refractive-index profile minimizes differential mode delay, enabling full 300-meter 10GBASE-SR reach and 100-meter 40G/100G reach required by TIA-568.3-D and ISO/IEC 11801-1. The FRXTP77Y001F078 uses Corning or equivalent low-water-peak OM3 fiber with <0.35 dB/km attenuation at 850nm and <1.5 dB/km at 1300nm, ensuring multi-decade link budgets even after connector mating cycles and environmental aging. The 12-fiber count provides six duplex channels - sufficient for a 10G uplink trunk between access and aggregation layers, or three 40GBASE-SR4 links (4 fibers each) in spine-leaf architectures. Type B polarity is the TIA-recommended standard for duplex systems: with straight-through patch cords at both ends, Tx on one end connects to Rx on the far end without polarity inversion or crossover cords. Each LC duplex connector is keyed and latched to prevent accidental disconnection, with push-pull release tabs that remain accessible in high-density panels.

Plenum rating is mandatory for cable installed in HVAC ducts, drop ceilings, raised floors, or any air-handling space per NEC 770.113. The FRXTP77Y001F078's OFNP jacket is a low-smoke, halogen-free compound that self-extinguishes and limits flame spread to 5 feet per UL 910 (Steiner Tunnel Test), preventing fire propagation through air plenums. This eliminates the cost and space penalty of metallic conduit in above-ceiling horizontal distribution or vertical riser shafts between telecom rooms. The 3.0mm round cable diameter keeps pathway fill ratios low - twelve 3.0mm cables occupy the same tray width as three 12-strand distribution cables, preserving airflow and future capacity. Pre-termination cuts deployment time by 80% compared to field fusion splicing or mechanical termination: a typical 12-fiber trunk that would require 24 connector terminations, 24 end-face inspections, and two-tier OTDR testing instead installs in under 15 minutes with zero consumables. Factory test reports document <0.35 dB average insertion loss and >20 dB return loss per duplex connector, values that field crews rarely achieve without multiple polish attempts and contamination control. The serialized cable tags and port labels simplify as-built documentation and MAC (move-add-change) traceability in multi-tenant or colocation environments where audit trails are contractually required.

The Panduit Opti-Core trunk line is factory-assembled under cleanroom protocols with automated ferrule polishing, end-face inspection, and reel-to-reel insertion-loss testing at 850nm and 1300nm wavelengths. Every connector meets IEC 61300-3-35 ferrule geometry limits for radius of curvature, apex offset, and fiber height, ensuring <0.20 dB single-mode-equivalent performance even in multimode links. The aramid yarn strength members are anchor-terminated inside each connector boot, distributing tensile load across the cable jacket rather than the fragile 125µm fiber cladding. This assembly survives the 25 lbf pull loads common in vertical riser installations and the 10x bend radius flexing that occurs when cables are dressed into 1U patch panels. The 78-foot length is a standard specification for floor-to-floor riser spans in commercial buildings with 12-foot ceilings plus 15-20 feet of horizontal routing margin, or for horizontal runs from main cross-connects to intermediate distribution frames in large telecom rooms. The yellow LSZH jacket is UV-stable for 20-year outdoor exposure in aerial or building-entrance conduit applications, though this trunk is primarily specified for indoor plenum and riser installations. TIA-568.3-D, ISO/IEC 11801-1, and ANSI/TIA-942-B compliance ensures compatibility with structured cabling standards for commercial buildings and data center tier topologies, supporting procure-to-pay workflows that require standards-referenced BOMs and AHJ (authority having jurisdiction) inspection signoff.
