Panduit F923LSNSNSNM002 OS2 SC Duplex Fiber Patch Cord 2m

Panduit F923LSNSNSNM002 Opti-Core OS2 Single-Mode Fiber Patch Cord

Panduit F923LSNSNSNM002 is a 2-meter OS2 single-mode duplex fiber patch cord with SC duplex connectors on both ends, 3mm LSZH-rated cable jacket, and 9/125μm fiber. Built for data center, telecom room, and campus backbone interconnects where insertion loss, flame rating, and polarity management determine uptime. Part of Panduit's Opti-Core™ factory-terminated line—each cord ships with test reports showing <0.3dB insertion loss and >45dB return loss, eliminating the field-termination variability that kills link budgets on 10G/40G/100G Ethernet and 16G/32G Fibre Channel deployments.

Key Features

• OS2 9/125μm single-mode fiber certified to ISO/IEC 11801 and TIA-568-C.3 for distances up to 10km at 10GbE, 40km+ on 1GbE
• SC duplex (SC/PC) connectors both ends—keyed housings prevent A/B fiber reversal during moves-adds-changes
• 3mm round LSZH cable jacket meets IEC 60332-1 and 60754 low-smoke-zero-halogen requirements for enclosed pathways and international installations
• Yellow jacket per TIA-598-D OS2 single-mode color code—instant visual confirmation in mixed multi-mode/single-mode environments
• Factory-terminated and tested—each cord serialized with QR-code traceable insertion loss/return loss test data
• 2-meter (6.5ft) length suited for intra-rack panel-to-switch or cross-connect horizontals in telecom rooms

OS2 single-mode fiber is the backbone medium for any link over 300 meters or requiring 10 Gigabit and above. The F923LSNSNSNM002 uses 9/125μm fiber with <0.35dB/km attenuation at 1310nm and <0.25dB/km at 1550nm, supporting 10GBASE-LR (10km), 40GBASE-LR4 (10km), 100GBASE-LR4 (10km), and extended-reach 1G/10G optics beyond 40km when paired with appropriate transceivers. SC duplex terminations are the industry-standard connector for structured cabling—the push-pull latch design withstands 500+ mating cycles, and the 2.5mm ceramic ferrule maintains <0.15dB typical insertion loss across the installed base of enterprise switches, media converters, and SFP/SFP+ modules. Duplex configuration maintains transmit/receive pair polarity through the keyed connector body; A-fiber and B-fiber stay aligned from patch panel to equipment port without the polarity flips that plague LC uniboot designs during MAC layer troubleshooting.

The 3mm cable diameter balances density and handling. Standard 2mm simplex cables are fragile and prone to kinking below the 30mm bend radius minimum for 9/125μm fiber; 3mm jacketing provides crush resistance and bend protection for horizontal cable management without the 15mm-radius spool memory of 2mm zipcord. LSZH (Low Smoke Zero Halogen) jacketing is required by IEC 60332-1 for European installations and increasingly adopted in US data centers under NFPA 75 and Uptime Institute Tier IV guidelines—in a fire event, LSZH compounds emit <0.5% halogen gas and <50% visible smoke compared to PVC jackets, protecting personnel and sensitive equipment. Yellow jacket color follows TIA-598-D Annex A single-mode designation (multimode is aqua/orange); in telecom rooms with both fiber types, color-coding prevents the 14dB mode-field-diameter mismatch that occurs when a 50/125μm OM3 cord is accidentally patched into a 9/125μm OS2 link.

Factory termination eliminates the three failure modes that plague field-terminated fiber: epoxy contamination, ferrule end-face geometry outside the FOCIS-3 radius-of-curvature spec, and cleave-angle errors that push insertion loss above 0.5dB. Panduit Opti-Core cords are terminated in a controlled environment, then tested per IEC 61300-3-4 (insertion loss) and IEC 61300-3-6 (return loss); each cord's serial number links to a digital test record showing actual dB measurements at 1310nm and 1550nm. Typical insertion loss is <0.2dB; return loss exceeds 50dB (PC polish). This matters on 10GBASE-LR and 40G/100G links where the IEEE 802.3 power budget allocates only 2.6dB total channel loss for 10km reach—every 0.1dB consumed by a substandard patch cord reduces usable distance by 400 meters. SC/PC (Physical Contact) polish is standard; SC/APC (angled) variants are available under different MPNs for DWDM and PON applications requiring >60dB return loss.

The 2-meter length is the workhorse size for telecom rooms and data center meet-me interconnects. Use F923LSNSNSNM002 to interconnect fiber patch panels to core switches within the same relay rack, cross-connect MDA (main distribution area) panels to IDF (intermediate distribution frame) cassettes in structured cabling horizontals, or bridge equipment-rack switch uplinks to backbone trunk cables. At 6.5 feet, the cord provides enough service loop for panel repositioning and future MAC work without the cable-management burden of 5-meter or 10-meter lengths that create slack-loop clutter and exceed the 20x-diameter minimum bend radius (60mm for 3mm cable) when coiled in vertical managers. Panduit offers the same Opti-Core specification in 1m, 3m, 5m, 10m, and custom lengths; deploying a consistent product family across the fiber infrastructure ensures uniform insertion-loss budgeting and simplifies sparing.

Designed for TIA-568-C.3 and ISO/IEC 11801 structured cabling systems. Meets TIA-604-3 (FOCIS-3) SC connector geometry, TIA-604-10 (FOCIS-10) duplex-clip mechanical specs, and IEC 61754-4 SC interface standards. LSZH jacket complies with IEC 60332-1 (flame propagation), IEC 60754-1 (halogen content <0.5%), and IEC 61034 (smoke density <50%). Suitable for building risers, horizontal pathways, equipment rooms, and entrance facilities under NFPA 70 (NEC) Article 770 and international fire codes. Panduit Opti-Core fiber patch cords carry a manufacturer warranty covering materials and factory-termination workmanship—register the serial number within 30 days of installation to activate warranty coverage and access the digital test-report archive for MAC documentation and TIA-606-B labeling compliance.
