Panduit F91ELANB1SNM007 Opti-Core OS2 Single-Mode Fiber Patch Cord

The Panduit F91ELANB1SNM007 is a 7-meter OS2 single-mode fiber patch cord with SC APC and LC/APC angled-polish connectors, 1.6mm simplex cable diameter, and LSZH jacket. Built for security surveillance networks, datacenter interconnects, and telecom installations where low back-reflection and fire-safety compliance are required. Standard insertion loss spec ensures reliable link budgets in long-distance single-mode runs. Ships as part of Panduit's Opti-Core fiber system, a structured-cabling platform used across enterprise and critical-infrastructure deployments.

Key Features

OS2 single-mode fiber rated for 10G/40G/100G transmission over distances up to 10 km

SC APC (simplex) to LC/APC (simplex) termination — angled polish reduces return loss to -60 dB or better

1.6mm simplex cable diameter — compact bend radius for high-density patch panels and tight pathways

LSZH (Low Smoke Zero Halogen) jacket meets EN 60332-1-2 — required for plenum and riser installations in Europe and increasingly specified in North America for occupied spaces

7-meter (23 ft) length — sized for typical rack-to-rack or enclosure-to-enclosure runs in server rooms and IDF closets

Standard insertion loss — factory-tested and labeled for predictable link-budget planning

Yellow jacket follows TIA-598-C color code for single-mode fiber identification

Opti-Core sub-brand — Panduit's fiber platform with lifetime warranty and cross-product compatibility

Single-mode OS2 fiber is the backbone of modern IP surveillance and datacenter networks. The 9-micron core supports 10GBASE-LR, 40GBASE-LR4, and 100GBASE-LR4 over multi-kilometer distances with minimal chromatic dispersion. The APC (Angled Physical Contact) polish on both SC and LC connectors cuts Fresnel reflection by an order of magnitude compared to UPC flat-polish — critical for DWDM systems, high-speed Ethernet, and any application where reflected energy can destabilize transmitters or corrupt forward error correction. The SC connector is spring-loaded and keyed to prevent accidental disconnection; the LC connector uses a latch mechanism and occupies half the footprint of SC, making it the standard for SFP/SFP+ transceiver modules in switches and media converters. Both connectors in this assembly use simplex (single-fiber) form factors — this is a one-strand cable, not a duplex zip-cord. Typical deployment: SC end terminates at a wall-mounted fiber enclosure or patch panel; LC end plugs into a network switch or NVR with SFP+ fiber ports.

The LSZH jacket is a hard requirement in European installations under CPR (Construction Products Regulation) Euroclass ratings and increasingly common in North American healthcare, transportation, and high-rise buildings where smoke toxicity and optical obscuration during fire are life-safety concerns. Standard PVC jackets release hydrochloric acid and dense black smoke when burned; LSZH compounds emit water vapor and light gray smoke with minimal acid gas. This cable meets EN 60332-1-2 vertical flame propagation limits. The 1.6mm diameter is part of Panduit's Opti-Core "micro" cable family — thinner than the legacy 2.0mm or 3.0mm zip-cord designs, allowing higher port density in 1U patch panels and tighter bend radii in overhead cable trays. The 7-meter length is a stock size that fits the majority of rack-to-rack and row-to-row spans in co-location facilities, campus MDFs, and large-scale surveillance head-end rooms without excessive service loops.

Standard insertion loss (IL) means the cable ships with a test report certifying connector performance within TIA-568 or IEC 61300-3-4 limits (typically ≤0.5 dB per connection for single-mode APC). This eliminates the need for field testing and ensures the patch cord can be included in loss-budget calculations for link certification. Panduit Opti-Core fiber products carry a lifetime warranty and are manufactured in ISO 9001-certified facilities with end-face inspection on every terminated connector. The yellow jacket and Opti-Core branding make this cable instantly recognizable as single-mode infrastructure in mixed fiber/copper environments.
