Panduit FZ2ELQ1SNSNM048 OM4 48m LC/SC Trunk

Panduit FZ2ELQ1SNSNM048 OM4 48-Meter Pre-Terminated LC/SC Fiber Trunk

The Panduit FZ2ELQ1SNSNM048 is a factory-terminated 48-meter (157.5 ft) OM4 multimode fiber trunk with LC duplex connectors on one end and SC duplex on the other, designed for rapid deployment in datacenter vertical risers, inter-floor backbone links, and equipment distribution areas where hybrid connector configurations bridge legacy SC infrastructure with modern LC-based active equipment. The 2-fiber trunk uses 50/125µm OM4 laser-optimized multimode fiber rated for 10GBASE-SR up to 400m, 40GBASE-SR4 to 150m, and 100GBASE-SR10 to 150m, eliminating field termination labor and the insertion-loss variability that comes with on-site connectorization. LSZH jacketing meets low-smoke zero-halogen flammability requirements for enclosed spaces, air-handling plenums, and international installations where PVC combustion byproducts create unacceptable toxicity risk. QuickNet™ pre-terminated trunks ship with factory test reports documenting insertion loss ≤0.3 dB and return loss ≥-20 dB per connector pair, providing traceable performance verification that field-terminated links cannot match without expensive OTDR validation.

Key Features

• OM4 50/125µm laser-optimized multimode fiber supports 10/40/100 Gigabit Ethernet over extended distances (10G to 400m, 40G/100G to 150m per IEEE 802.3)
• Hybrid LC duplex to SC duplex configuration bridges modern SFP+/QSFP+ transceiver platforms with legacy SC patch panels and fiber distribution frames
• 48-meter engineered length suits vertical riser runs between floors in multi-story facilities, eliminating splice points and associated loss budgets
• Push-pull LC connector design enables single-handed insertion/extraction in high-density 1U fiber panels where standard LC boot tabs are inaccessible
• Low Smoke Zero Halogen (LSZH) jacket complies with IEC 60332-1 flame propagation and IEC 61034-2 smoke density limits for enclosed building spaces
• Factory termination and testing guarantees ≤0.3 dB insertion loss per connector, ≤0.15 dB per mated pair — eliminating the 0.5-0.75 dB typical loss of field-terminated connectors
• 1.6mm mini-distribution cable diameter reduces pathway fill in vertical cable trays and 4-inch conduit runs compared to 2.0-3.0mm breakout trunks
• TIA-568.3-D and ISO/IEC 11801 compliance ensures interoperability with structured cabling standards for commercial buildings and datacenters
• QuickNet™ pull-through design with integrated pull-eye and sequential meter markings simplifies installation through vertical risers and long conduit runs
• Aqua jacket color per TIA-598-D OM4 fiber identification standard prevents cross-connection errors with OM3 (aqua), OM2 (orange), or single-mode (yellow) infrastructure

The 50/125µm OM4 fiber core uses laser-optimized graded-index glass composition with effective modal bandwidth ≥4700 MHz·km at 850nm, supporting 10GBASE-SR to 400 meters without mode conditioning patches or single-mode transceiver upgrades. This bandwidth headroom extends reach beyond OM3's 300m limit for 10G links, critical in large datacenter pods where top-of-rack to end-of-row aggregation switches exceed 200-meter horizontal + vertical cable runs. For 40GBASE-SR4 and 100GBASE-SR10 parallel optics deployments, OM4 maintains 150-meter channel length versus OM3's 100-meter ceiling — the difference between single-hop spine-leaf architectures and forced aggregation layer splits that double switching latency. Factory-polished LC and SC connectors use physical-contact (PC) endface geometry with ≤50nm apex offset, achieving the <-20 dB return loss required to prevent Fabry-Perot cavity reflections that degrade VCSEL transmitter eye diagrams at 25Gbps per lane modulation rates. The 1.6mm mini-distribution cable construction uses aramid yarn strength members and a tight-buffered 900µm secondary coating over each fiber, providing 100N short-term tensile rating and 5mm bend radius compliance — tighter than the 10x cable diameter (16mm) minimum of standard distribution cables, enabling sharper turns through crowded vertical cable trays without macrobend attenuation spikes above 0.2 dB at 850nm.

The hybrid LC-to-SC connector configuration solves a specific migration problem in enterprise datacenters and telecom central offices: active 10G/40G equipment (switches, storage arrays, media converters) standardized on LC duplex SFP+/QSFP+ form factors in 2010-2020, while backbone fiber infrastructure installed in 2000-2010 used SC connectors on main distribution frame (MDF) and intermediate distribution frame (IDF) panels. Rather than re-terminate thousands of SC-based permanent links or deploy LC-to-SC conversion modules that add insertion loss and failure points, the FZ2ELQ1SNSNM048 trunk provides a direct equipment-room-to-riser interface: LC end plugs into the switch/server, SC end mates with existing building backbone terminations. The 48-meter length maps to vertical riser distances in 8-12 story commercial buildings (assuming ~12-15 ft floor-to-floor height + horizontal offset + service loop), eliminating the need for mid-run splice enclosures that introduce 0.3-0.5 dB loss per splice point and create failure modes during building vibration or temperature cycling. LSZH jacketing meets the IEC 60332-1-2 vertical flame propagation test (flame spread ≤50mm after 60s exposure) and IEC 61034-2 smoke density test (light transmittance ≥60% in 3m³ chamber), required by NFPA 90A for air-handling spaces, European CPR Construction Products Regulation for Euroclass Cca-s1a,d1 cables, and many Asian/Pacific building codes that prohibit halogenated polymers in occupied floors.

Installation follows TIA-568.3-D Annex E pre-terminated trunk guidelines: pull-eye attachment torque ≤2.7 N·m, maximum pull tension 100N with swivel pulling grip to prevent jacket rotation, and ≥5x cable diameter service loops at each termination point to accommodate future re-routes without re-pulling the trunk. The sequential meter markings printed every meter allow installers to verify actual deployed length against as-built drawings during acceptance testing, and the 1.6mm diameter enables up to 12 trunks (24 fibers) in a single 4-inch conduit run without exceeding the NEC 40% fill ratio for new construction (2.03 in² jam ratio area). Push-pull LC connectors use a spring-loaded sliding boot that covers the connector body during insertion and retracts to expose a 6mm-wide pull tab, eliminating the need to reach behind adjacent connectors in 1U LC panels where 0.5-inch port spacing leaves no finger clearance for standard LC squeeze-tab release. QuickNet™ factory testing uses automated insertion-loss test sets calibrated to TIA-526-14-C Method B (one-jumper reference) with Grade B ceramic reference connectors, producing per-link reports that document worst-case connector loss ≤0.3 dB and fiber link loss ≤0.5 dB including connector pair — values low enough to meet ISO/IEC 11801 Class OM4 channel insertion loss limits (2.6 dB at 10G, 1.9 dB at 40G/100G for 500m channel) even after adding four mated connector pairs (equipment + patch panel + cross-connect + equipment) and 0.15 dB attenuation per 48 meters of OM4 fiber. For ANSI/TIA-942-B datacenter compliance, the trunk meets Table 9.1 Tier III/IV permanent link performance (≤1.46 dB insertion loss for ≤90m OM4 horizontal + 10m backbone allocation) and Annex I environmental specifications for 0-60°C operating range and 85% RH non-condensing humidity, ensuring reliable 40GBASE-SR4 operation in hot-aisle containment zones where ambient temperatures approach ASHRAE A3/A4 thermal class limits.
