Panduit F923LSNSNSNM1.5 1.5m OS2 SC Duplex Fiber Cable

Panduit F923LSNSNSNM1.5 OS2 Singlemode Fiber Patch Cable

The Panduit F923LSNSNSNM1.5 is a 1.5-meter OS2 singlemode fiber optic patch cable engineered for high-density data center and telecommunications installations where fire safety, low insertion loss, and rapid deployment are critical. Featuring duplex SC connectors on both ends, 9/125µm OS2 fiber cores, and a 3mm LSZH (Low Smoke Zero Halogen) jacket, this 2-fiber cable delivers the performance and compliance required for 10G/40G/100G Ethernet, Fibre Channel, and long-haul telecom links in mission-critical environments.

Key Features

• OS2 Singlemode Performance: 9/125µm fiber cores support transmission distances up to 10km (10GBASE-LR), 40km (10GBASE-ER), and beyond — ideal for campus backbone, metro, and storage-area-network (SAN) applications where multimode reach is insufficient.
• Factory-Terminated SC Duplex Connectors: Pre-polished Physical Contact (PC) SC connectors on both ends eliminate field termination labor, reduce insertion loss to <0.3dB typical, and ensure consistent return loss performance across the link.
• LSZH Jacket for Plenum-Alternative Installations: Low Smoke Zero Halogen outer jacket meets stringent fire-safety requirements for enclosed spaces, producing minimal smoke and no halogenated toxins during combustion — critical for occupied equipment rooms, risers, and international deployments where PVC is prohibited.
• 3mm Diameter for High-Density Routing: Compact 3mm cable profile (versus 2mm zipcord or 1.6mm microcable) balances flexibility with durability, fitting standard fiber management trays, patch panels, and cable managers without excessive bend-radius strain.
• TIA/ISO Standards Compliance: Tested and qualified to TIA-568.3-D, ISO/IEC 11801, and ITU-T G.652.D for chromatic dispersion, attenuation, and geometry — ensuring interoperability with all standards-based singlemode transceivers and media converters.
• 2-Fiber Duplex Configuration: Supports full-duplex bidirectional communication (Tx/Rx on separate fibers) for Ethernet switches, storage arrays, and telecom equipment requiring simultaneous transmit and receive paths.

Installation Context: Singlemode OS2 fiber is the backbone choice for data centers, carrier hotels, and enterprise campuses where link distances exceed 300 meters or future bandwidth scaling to 100G/400G is anticipated. The SC duplex connector — while gradually being displaced by LC in new greenfield builds — remains the dominant installed-base standard in telecom central offices, older enterprise cores, and equipment with fixed SC interfaces (legacy Cisco, Brocade, Juniper line cards). The 1.5-meter length is a common patch length for intra-rack connections (server to top-of-rack switch) or cross-connect jumpers in meet-me rooms where structured cabling terminates on SC-interface patch panels.

LSZH Jacket Trade-offs: LSZH compounds are mechanically softer than PVC or plenum-rated fluoropolymer (OFNP), making them more susceptible to crush damage during installation and less resistant to UV degradation in outdoor or aerial environments. However, for indoor-only applications — particularly in Europe, healthcare facilities, transit systems, and occupied high-rises — LSZH is often code-mandated. Installers should route LSZH cables in protected pathways (conduit, cable tray, ladder rack) and avoid exposing them to continuous UV or mechanical abrasion. The 3mm diameter provides adequate crush resistance for typical equipment-room floor-trench and overhead-runway installations, but should not be used in underfloor applications where heavy rack casters may roll over unprotected cable.

Deployment Considerations: OS2 singlemode fiber requires singlemode transceivers (typically 1310nm or 1550nm lasers) on both ends — multimode transceivers (850nm VCSEL) will not function over singlemode fiber. Verify transceiver wavelength and reach specifications before deployment: 10GBASE-LR (10km, 1310nm), 10GBASE-ER (40km, 1550nm), 40GBASE-LR4 (10km, CWDM 1310nm), and 100GBASE-LR4 (10km, LAN-WDM) all require OS2 fiber and deliver substantially longer reach than multimode OM3/OM4 alternatives. For links under 300 meters, multimode OM3 or OM4 fiber with lower-cost multimode transceivers often provides better ROI — but singlemode future-proofs the physical infrastructure for 25G/50G/100G upgrades without re-cabling.

Polish and Connector Care: The Physical Contact (PC) polish on the SC connectors provides end-face contact that minimizes air gaps and achieves <0.3dB insertion loss and >40dB return loss in typical installations. For applications requiring ultra-low back-reflection (analog video transport, high-bitrate DWDM, coherent optics), consider UPC (Ultra Physical Contact, >50dB return loss) or APC (Angled Physical Contact, >60dB return loss) variants instead. Always inspect fiber end-faces with a microscope before mating — dust, oils, and scratches are the leading cause of intermittent link errors and transceiver damage. Use lint-free wipes, isopropyl alcohol, and one-click cleaners per IEC 61300-3-35 procedures, and store unused connectors with dust caps installed.

This cable meets TIA-568.3-D Category OS2 specifications for maximum attenuation (1.0 dB/km at 1310nm, 1.0 dB/km at 1550nm) and chromatic dispersion, ensuring compatibility with all standards-based singlemode equipment. Panduit's factory termination process includes automated end-face inspection, IL/RL performance verification, and pull-test validation — delivering out-of-box reliability that field-terminated connectors cannot match. The duplex SC footprint is compatible with standard 19-inch fiber patch panels, wall-mount enclosures, and rack-mount cassettes, simplifying integration into existing structured cabling systems.
