Panduit FSDL906 6-Fiber OS2 Indoor Distribution Cable

The Panduit FSDL906 delivers six strands of OS2 single-mode fiber in a compact, LSZH-rated indoor distribution cable. Built around 900µm tight-buffered fibers, this cable is designed for premise installations where code-compliant low-smoke construction, individual fiber handling, and long-haul single-mode transmission converge. Whether you're feeding datacenter racks, linking floors in a high-rise, or extending enterprise backbones across campus buildings, the FSDL906 gives you the strand count and fire-safety rating that modern structured cabling projects demand—without the bulk of traditional loose-tube designs.

Key Features

• Six OS2 single-mode fibers (9/125µm) rated for distances up to 10+ km at 10 Gb/s, 40 km+ at 1 Gb/s
• 900µm tight-buffered construction—each fiber individually jacketed for direct termination and simplified breakout
• Low Smoke Zero Halogen (LSZH) jacket meets IEC 60332-1 and 60332-3C flame test requirements, suitable for plenum-alternative and occupied-space installs where local codes mandate low-smoke materials
• Yellow jacket for instant single-mode identification on job sites and in cable trays
• Compact OD reduces pathway fill and eases pulling through crowded conduit and cable trays
• Panduit Opti-Core® sub-brand—engineered for consistent insertion loss and backed by Panduit's structured cabling warranties

Single-mode OS2 fiber is the backbone choice for any link that needs to scale beyond 1 Gb/s or span more than 300 meters. The FSDL906's 9µm core and tight manufacturing tolerances deliver insertion loss under 0.4 dB/km at 1310 nm and 0.3 dB/km at 1550 nm, ensuring your 10GBASE-LR, 40GBASE-LR4, and future 100G optics see clean signal across multi-kilometer runs. The 900µm tight-buffered design means each fiber is encased in its own 900µm protective layer—a critical advantage when you're punching down in a rack or breakout box. Unlike loose-tube cables that require costly fan-out kits and added labor, tight-buffered fibers strip cleanly and terminate directly into LC, SC, or MPO connectors using standard cleavers and fusion splicers. Installers save time, and the risk of damaging bare 250µm fiber during handling drops to near zero. The LSZH jacket formulation is halogen-free PVC alternative that produces minimal smoke and no corrosive acid gases during combustion—essential for enclosed spaces like equipment rooms, risers, and horizontal pathways in occupied buildings where PVC smoke could obscure egress or damage sensitive electronics.

Deploy the FSDL906 in datacenter hot-aisle to MDA links, campus backbone runs between IDFs, or as vertical riser cable in multi-tenant office towers. The six-fiber count gives you three duplex circuits—enough for a primary link, a standby path, and a spare pair for future growth or out-of-band management. Pair it with Panduit's cassette modules and pre-terminated MPO trunks for rapid rack-to-rack interconnects, or terminate into individual LC duplex connectors for traditional patch-panel breakouts. Because it's rated LSZH rather than plenum (CMP), verify that your local jurisdiction accepts LSZH in the intended pathway—many international markets and an increasing number of US municipalities now prefer or require LSZH over PVC plenum for environmental and safety reasons. The yellow jacket is the universal single-mode color code (TIA-598-C), so your team will never confuse this cable with aqua OM3 or lime OM5 multimode runs. Typical applications include 10GBASE-LR SFP+ uplinks at 10 km, 1000BASE-LX at 5–40 km, and future 25G/40G/100G optics that demand the low dispersion and attenuation only single-mode fiber can provide.

The FSDL906 is sold by the foot as bulk cable, letting you order exactly the length your project needs and terminate on-site or send to a Panduit-certified shop for factory-grade assemblies. Each fiber meets or exceeds TIA-492-CAAA (OS2) geometry and attenuation specs, and the cable itself ships with Panduit's standard structured cabling warranty when installed per Panduit guidelines and registered within 90 days. For integrators building code-compliant, future-proof fiber plants in commercial or institutional environments, the FSDL906 delivers the strand count, safety rating, and ease of termination that keeps projects on schedule and within budget.
