Panduit FRXTP77Y001F076 12-Fiber OM3 Plenum Trunk 76ft

Panduit FRXTP77Y001F076 Opti-Core 12-Fiber OM3 Plenum Trunk Cable

The Panduit FRXTP77Y001F076 is a factory-terminated 12-fiber OM3 multimode trunk cable engineered for high-speed datacenter and enterprise network backbones. This 76-foot plenum-rated assembly delivers plug-and-play deployment of 10/40/100 Gigabit Ethernet links between distribution frames, zone enclosures, and top-of-rack switches. Pre-terminated female MTP connectors on both ends eliminate field termination labor and testing overhead while the Polarity B pin-out configuration supports structured 40GBASE-SR4 and 100GBASE-SR4 parallel optics deployments without adapter flipping or custom patch cord schemes. Plenum OFNP jacketing meets NEC Article 770 for installation in air-handling spaces above drop ceilings and under raised floors. For integrators managing rapid datacenter builds, server room expansions, or telecom facility upgrades where downtime windows are measured in hours and every dB of insertion loss matters, this Opti-Core trunk delivers the balance of speed, compliance, and performance headroom required to meet SLA commitments.

• 76-foot (23.2-meter) length engineered for typical datacenter row-to-MDA and horizontal distribution applications where pre-measured runs reduce cable slack and airflow obstruction
• Aqua OM3-standard jacket color for instant visual identification in mixed-mode fiber plants and simplified MAC (Moves, Adds, Changes) operations
• Pin-and-key MTP connector interface ensures correct polarity alignment, prevents mis-mating with single-fiber connectors, and supports breakout to duplex LC with standard Polarity B cassettes or harnesses
• TIA-568.3-D, ISO/IEC 11801, and ANSI/TIA-942-B data center cabling standard compliance ensures interoperability with Cisco, Juniper, Arista, and standards-based 40G/100G optics modules
• Panduit Opti-Core manufacturing process with automated connector inspection, end-face geometry verification, and insertion loss testing at 850nm and 1300nm wavelengths ships every trunk with serialized test data
• Low-smoke, zero-halogen (LSZH) alternative available for international deployments and facilities with stricter fire safety codes (consult factory for LSZH part number cross-reference)
• Backward-compatible with existing OM1/OM2 infrastructure when used with mode-conditioning patch cords for 1000BASE-LX migrations

OM3 fiber delivers 2000 MHz·km effective modal bandwidth at the 850nm wavelength used by cost-effective VCSEL transceivers in 10G, 40G, and 100G short-reach applications. This bandwidth headroom translates to channel reach of 300 meters at 10 Gb/s (sufficient for 98% of intra-building datacenter links) and 100 meters at 40/100 Gb/s, covering typical top-of-rack to end-of-row aggregation switch distances with margin to spare. The 50µm graded-index core minimizes differential mode delay compared to legacy 62.5µm OM1 fiber, reducing intersymbol interference and bit error rates on high-speed parallel optics links where eight or twelve lanes transmit simultaneously. Each fiber strand in this trunk meets the TIA-568.3-D attenuation specification of ≤3.0 dB/km at 850nm and ≤1.0 dB/km at 1300nm, ensuring that even after connector insertion loss (typically 0.25-0.35 dB per mated pair) and splice loss budgets, you retain 1-2 dB margin against the IEEE 802.3 worst-case link loss allocations. The MTP connector interface uses a ferrule with twelve or twenty-four fiber positions in a single rectangular footprint approximately the size of an SC duplex connector, achieving 6x to 12x port density improvement over traditional duplex LC infrastructure—a critical advantage when switch faceplate real estate costs hundreds of dollars per RU and cable management pathways are congested.

Polarity B configuration follows the TIA-568.3-D Type B mapping scheme where fiber position 1 on end A maps to position 12 on end B, position 2 to 11, and so forth in a flip pattern. This allows a single female-to-female trunk to directly interconnect two male MTP ports (such as those on 40GBASE-SR4 QSFP+ modules or structured cabling cassettes) without requiring a key-up to key-down adapter or crossover patch cord. In a typical deployment, this trunk runs from a 12-fiber MTP cassette in your main distribution area (MDA) to a zone distribution enclosure or equipment rack, where it breaks out to twelve duplex LC ports via a Polarity B fanout cassette. The result is a standards-compliant duplex fiber path for twelve 10G links or three 40G links (each consuming four fibers in parallel) with predictable transmit-receive pairing and no field re-termination. The female push-pull tab design protects the ferrule end-face during handling and installation; the MTP connector body includes a removable dust cap and ships with insertion/extraction force rated for 500 mating cycles per EIA-455-21 mechanical endurance testing. Cable routing benefits from the trunk's 1.6mm tight-buffered fiber construction inside a 6.8mm overall diameter jacket—flexible enough to navigate dense overhead ladder rack and vertical riser pathways while maintaining the 30mm minimum bend radius required to prevent macrobending attenuation. Plenum OFNP rating means the jacket passes UL 910 Steiner Tunnel flame and smoke tests with a maximum peak optical density of 0.5 and average optical density of 0.15, meeting or exceeding the NEC Article 770.179(A) requirements for cables installed in ducts, plenums, and other spaces used for environmental air without metallic conduit or raceway enclosure.

Factory testing per TIA-568.3-D Annex B includes insertion loss verification at 850nm and 1300nm, return loss measurement (≥20 dB typical), and automated interferometric end-face inspection confirming fiber height, apex offset, and radius of curvature meet IEC 61755-3-31 geometry specifications for multimode MPO connectors. Panduit ships each trunk with a serialized test report documenting per-fiber performance, ensuring you have audit-trail documentation for TIA-942-B Tier III/IV data center certification and ISO 9001 quality management systems. This trunk integrates into structured cabling architectures designed around centralized fiber distribution with local breakout—a topology that reduces the fiber pair count running to each equipment rack (one 12-fiber trunk replaces twelve duplex LC home runs), simplifies MAC operations (re-provision a port by swapping the LC patch cord at the zone cassette rather than re-pulling cable), and future-proofs for 40G/100G migration by re-using the same backbone trunk with different breakout cassettes or direct-attach MTP patch cords. For datacenter, telecom CO, enterprise campus, and healthcare IT deployments where fiber backbone installation happens during after-hours change windows and every hour of labor carries premium rates, pre-terminated trunks like the FRXTP77Y001F076 are the standard of practice—trading a modest material cost premium for elimination of fusion splicing equipment, OTDR testing overhead, and the field labor risk of damaged connectors or out-of-spec loss that requires expensive rework.
