Panduit F91EL3NB1SNM008 OS2 Single-Mode Fiber Patch Cord
The Panduit F91EL3NB1SNM008 Opti-Core® patch cord delivers OS2 single-mode connectivity for long-distance datacenter and backbone installations where you need to bridge SC and LC/APC terminations. The 8-meter length handles rack-to-rack or cross-room runs without excess slack, while the LSZH jacket meets plenum and riser air-quality mandates. SC simplex on one end and angle-polished LC/APC on the other let you connect legacy fiber panels to modern switch optics or media converters without adapter hassle.
Key Features
- OS2 single-mode fiber (9/125 μm core) supports distances up to 10 km and beyond at 10G/40G/100G rates
- LC/APC angle-polished connector reduces back-reflection below -60 dB for analog video, DWDM, and high-bitrate links
- SC simplex to LC simplex topology bridges fiber distribution panels and switch SFP/SFP+ cages
- 8-meter (26.2 ft) length fits typical rack-to-rack or cross-room deployments without excess coiling
- LSZH (Low Smoke Zero Halogen) jacket complies with IBC Chapter 8 and NEC Articles 770/800 for plenum and riser pathways
- 1.6 mm tight-buffer construction simplifies handling and termination compared to 900 μm cordage
- Yellow cable color matches TIA-598-C standard for single-mode OS2 identification
- Standard Insertion Loss specification (typically ≤0.3 dB) ensures predictable link budgets
- EN 60332-1-2 flame-propagation rating for European and international compliance
OS2 single-mode fiber uses a 9 μm core to propagate a single light mode, eliminating modal dispersion and enabling multi-kilometer runs at 10GBASE-LR, 40GBASE-LR4, or 100GBASE-LR4 speeds. The LC/APC connector employs an 8° angle polish that directs back-reflected light into the cladding rather than the core—critical when you're running analog CCTV over fiber, deploying DWDM multiplexers, or maintaining <-60 dB return loss for coherent optics. SC simplex on the opposite end mates with older fiber distribution frames, wall plates, or patch panels that predate the LC form factor, so you avoid stacking adapters or re-terminating legacy infrastructure.
The 8-meter length bridges in-row racks, crosses to adjacent enclosures, or spans small equipment rooms without leaving tangles of excess cable—measure your pathway, add a service loop, and you're done. LSZH jacketing replaces PVC with halogen-free compounds that emit 5× less smoke and zero corrosive acid gases during combustion, satisfying IBC 805.5.1 and NEC 770.113 for plenums and risers where polyvinyl chloride is prohibited. Yellow coloring follows TIA-598-C Appendix A so technicians recognize single-mode at a glance, and the 1.6 mm tight-buffer design is stiff enough to route cleanly yet flexible enough to dress into cable managers.
Panduit manufactures every Opti-Core® patch cord under ISO 9001 process controls, end-face inspects every connector, and serializes each cable for traceability. Installation takes seconds—wipe the ferrule with a lint-free swab dampened in >99% isopropyl alcohol, mate into the target port until you hear the click, and verify link light. Insertion loss ships below 0.3 dB per connector pair, and return loss exceeds the -60 dB threshold that analog video transmission and DWDM systems demand. EN 60332-1-2 flame testing confirms that a single vertical specimen self-extinguishes within the prescribed char height, meeting European Directive 2013/35/EU and international fire codes without requiring a separate plenum-rated variant.
