Panduit FRXTP77Y001F067 12-Fiber OM3 Plenum Trunk Cable

Pre-terminated fiber infrastructure that eliminates field termination risk and accelerates deployment timelines in mission-critical environments. This 12-fiber OM3 trunk delivers factory-tested 10/40GBASE-SR performance across a 67-foot span, with plenum-rated OFNP jacketing for unrestricted above-ceiling routing. FE-FE (duplex LC) connectors on both ends follow TIA-568 Polarity B configuration, ensuring plug-and-play compatibility with structured cabling standards. Factory assembly means insertion loss and return loss are characterized before shipment—no guesswork, no rework. Designed for data center spine connections, telecom equipment distribution areas, and horizontal fiber links where installation windows are measured in hours, not days.

Key Features

• 12-fiber OM3 (50/125µm) trunk—supports 10GBASE-SR to 300m, 40GBASE-SR4 to 100m per IEEE 802.3
• Plenum-rated OFNP jacket meets NEC Article 770 for air-handling spaces without conduit
• Pre-terminated FE-FE (duplex LC) connectors with TIA-568 Polarity B configuration
• 67-foot (20.4m) length—factory-cut for common rack-to-rack or closet-to-closet spans
• Factory tested for insertion loss ≤0.35dB and return loss ≥-20dB per TIA-568.3-D
• Opti-Core® sub-brand—Panduit's engineered fiber platform with lifetime warranty

The OM3 50/125µm laser-optimized multimode fiber core supports both legacy 1000BASE-SX (Gigabit Ethernet) and contemporary 10GBASE-SR links, with sufficient modal bandwidth (2000 MHz·km at 850nm) to handle 40GBASE-SR4 parallel optics over distances up to 100 meters. This makes it the standard choice for data center leaf-spine architectures where you're aggregating 10G server uplinks into 40G or 100G spines. The 12-fiber count provides six duplex channels—enough for a redundant pair of 40G QSFP+ links (which consume four fibers each in SR4 mode) or twelve independent 10G SFP+ connections. Polarity B (straight-through A-to-A, B-to-B mapping) is the default method for duplex LC patch cords and trunk cables in TIA-568.3-D; it pairs naturally with MPO-to-LC breakout harnesses and requires no crossover adapters when connecting switches to panels. Both ends terminate in factory-installed duplex LC connectors, which Panduit pre-polishes to better than 0.35dB insertion loss and validates with automated interferometric inspection. Return loss exceeds -20dB across all fibers, ensuring clean optical return for bidirectional transceivers and minimizing reflective crosstalk in dense wavelength environments.

Pre-terminated trunks collapse what would normally be a multi-step field process—measure, pull, strip, cleave, polish, test—into a single pull-and-plug operation. In a telecom equipment room upgrade or data center hot-aisle build, that difference translates to hours saved per trunk, with zero risk of contaminated end-faces or mismatched fiber counts. The 67-foot factory length is engineered for typical equipment distribution area layouts: main distribution frame to intermediate cross-connect, top-of-rack to end-of-row aggregation switch, or entrance facility to telecom room. Plenum-rated OFNP jacketing (per UL 910 and NEC 770.113) allows unrestricted routing through HVAC plenums, drop ceilings, and raised floors without additional conduit—critical when you're working in existing buildings where conduit pulls would require asbestos surveys or structural permits. The cable's low-smoke, flame-retardant outer jacket also simplifies AHJ inspections and closeout documentation. For installations spanning multiple equipment racks, the 12-fiber configuration provides enough strand count to segment voice, data, and storage networks onto dedicated fiber pairs while maintaining physical diversity and fault isolation.

Compliance extends beyond flammability: TIA-568.3-D structured cabling, ISO/IEC 11801 generic cabling, and ANSI/TIA-942-B data center telecommunications infrastructure standards all recognize OM3 as the minimum multimode grade for contemporary 10G/40G deployments. Panduit's Opti-Core® platform adds factory characterization data, serialized labeling for as-built documentation, and a lifetime warranty that covers both the cable assembly and the labor to replace it—eliminating the ambiguity that arises when field-terminated links fail and you're left troubleshooting whether the issue is cable, connectors, or technique. For integrators managing SLA-backed projects where downtime costs are measured in thousands per hour, factory-terminated infrastructure isn't a convenience—it's a risk transfer mechanism that moves quality control from the field to a controlled manufacturing environment.
