Panduit FR9TL55B001M017 17m ST Fiber Trunk - Polarity B

Panduit FR9TL55B001M017 Opti-Core 17-Meter ST Fiber Trunk Cable - Polarity B

The Panduit FR9TL55B001M017 is a factory-terminated 17-meter (55.8 ft) fiber optic trunk cable engineered for rapid deployment in data centers, telecommunications rooms, and entrance facilities where pre-tested connectivity eliminates field termination risk. Built to Polarity B standards with ST duplex connectors on both ends, this Opti-Core trunk delivers insertion loss specifications suitable for 10/40/100G links across multi-mode infrastructure, cutting install time from hours to minutes while maintaining strict loss budgets required for modern high-speed transceivers.

Key Features

• Factory-terminated ST duplex connectors with Polarity B configuration for structured cabling deployments requiring transmit/receive lane alignment
• 17-meter rated length bridges typical inter-row or cross-aisle distances in equipment distribution areas without excess slack management
• Opti-Core construction delivers <0.75 dB maximum insertion loss per mated pair, preserving link budget for 850nm/1300nm wavelength applications
• Red jacket color-coding per TIA-598 standards for instant 50/125µm OM2+ or OM3/OM4 fiber identification in dense pathways
• Pre-tested end-face geometry and continuity eliminate on-site inspection requirements, reducing commissioning labor by 60-80% versus field-terminated assemblies
• Ruggedized outer sheath and strain-relief boots withstand multiple install/remove cycles during MACs without connector damage

Field termination of multi-mode fiber introduces three failure modes that pre-terminated trunks eliminate: end-face contamination during epoxy cure, inconsistent polish geometry from hand tools, and polarity errors under time pressure. The FR9TL55B001M017 ships with factory-applied dust caps on all four connector ends, each interface tested for <0.5 dB insertion loss and <-50 dB return loss before packaging. When deploying 10GBASE-SR links between a core switch and access-layer aggregation point 17 meters apart, this trunk consumes roughly 1.5 dB of your 2.6 dB OM3 loss budget (0.75 dB for the trunk, 0.75 dB for two equipment patch cords), leaving comfortable margin for transceiver tolerances and aging. ST connectors remain common in legacy telecom environments and government installations where standardization on bayonet-lock interfaces predates LC adoption—this assembly directly supports retrofit upgrades without replacing wall boxes or panels.

Polarity B configuration (also called "straight-through" or "direct" mapping) aligns transmit fibers on one end to receive fibers on the opposite end without crossovers, simplifying trunk-to-trunk concatenation and passive splitting scenarios. In structured cabling designs using Method B polarity per TIA-568, the FR9TL55B001M017 serves as the backbone trunk between main distribution area (MDA) panels and horizontal distribution area (HDA) panels, with A-to-B patch cords completing the crossover at equipment connection points. The 17-meter length is field-measured to service typical raised-floor data center row spacing (12-15 meters of linear run) plus vertical rise to overhead cable tray and panel slack—eliminating the waste and pathway congestion of oversized 30-meter assemblies.

Opti-Core trunks undergo 100% factory inspection with automated interferometry to verify core alignment, ensuring consistency that hand-polished connectors cannot match. The red jacket follows TIA-598 color convention for OM2 (50/125µm) or can denote OM3/OM4 in installations using custom color schemes; verify fiber grade via the cable print legend or specification sheet before deployment in 40G/100G applications requiring OM3 (2000 MHz·km) or OM4 (4700 MHz·km) modal bandwidth. Installation requires no special tools—remove dust caps immediately before mating, insert ST connectors with bayonet twist to lock, and perform optical loss testing if commissioning standards mandate end-to-end verification. For surveillance control room buildouts connecting NVR management switches to camera aggregation switches across equipment rows, this trunk delivers the deterministic latency and multi-gigabit throughput that IP video walls and 4K monitoring stations demand.
