Description

Panduit FSDRA02Y Opti-Core 2-Fiber OS2 Indoor Riser Cable

The Panduit FSDRA02Y delivers bend-insensitive single-mode fiber infrastructure for IP camera backbones, datacenter interconnects, and building riser installations where long-distance runs and future-proof bandwidth matter. Built on G.657.A1 single-mode fiber in a 900µm tight-buffered construction, this 2-fiber OS2 cable handles 10G/40G/100G Ethernet and supports wavelengths from 1260nm to 1625nm with <0.4 dB/km attenuation at 1550nm. The OFNR (Riser) flame rating qualifies it for vertical shaft runs between floors, and the yellow PVC jacket signals single-mode fiber at a glance during installs and service calls. Field-terminated with LC, SC, or ST connectors, it's the backbone cable for integrators building point-to-point camera links over 300 meters, extending NVR storage to remote wiring closets, or running 10GBASE-LR uplinks from access switches to distribution layers in mid-rise commercial buildings.

Key Features

  • OS2 single-mode fiber (9/125µm) rated for <0.4 dB/km at 1550nm, supports 10km+ runs at 10Gbps without repeaters
  • G.657.A1 bend-insensitive specification tolerates 10mm bend radius (vs. 30mm for G.652.D) — tighter routing in cable trays and junction boxes without signal loss
  • 900µm tight-buffered construction for direct termination with fusion splicers or mechanical connectors, no fanout kits required
  • OFNR (Riser) flame rating per NEC Article 770 for vertical runs in non-plenum shafts, cable trays, and conduit between floors
  • Yellow PVC jacket color follows TIA-598-D single-mode standard, prevents cross-connections with multimode (orange/aqua) infrastructure during maintenance
  • 2-fiber count supports simplex transmission or single bidirectional link (1 fiber TX, 1 fiber RX) — right-sized for point-to-point IP camera uplinks or dedicated storage replication circuits

The tight-buffered 900µm design contrasts with loose-tube outdoor cables: each fiber gets its own 900-micron protective coating applied directly over the 250µm primary buffer, creating a mechanically stable structure you can cleave and terminate in the field without stripping multiple buffer layers. G.657.A1 bend performance matters in real installs — when fiber wraps around a 15mm radius patch-panel finger or loops inside a 4-inch junction box, legacy G.652.D fiber shows macro-bend attenuation spikes that kill 10G links; G.657.A1 spec requires <0.1 dB added loss at 1550nm for a 10mm-radius 360° loop. OS2 classification guarantees <0.4 dB/km at 1310nm and 1550nm, low enough for 10GBASE-LR (10km), 40GBASE-LR4 (10km), and 100GBASE-LR4 (10km) without inline amplifiers. The attenuation budget headroom also absorbs splice loss (typically 0.1-0.3 dB per fusion splice) and connector loss (0.3-0.5 dB per mated pair) on multi-span runs.

Typical deployments: Point-to-point IP camera runs from remote building perimeters to central NVR locations when distance exceeds Cat6a's 100-meter limit — a 4K camera 800 meters from the headend needs fiber, and OS2 handles that span with 0.32 dB loss (0.4 dB/km × 0.8 km) before connectors. Building riser runs connecting IDF switches on floors 2-12 to an MDF core switch in the basement — OFNR rating satisfies NEC 770.154(A) for vertical shafts not used for environmental air, and the 2-fiber count supports a single 10GBASE-LR uplink (you'd parallel multiple cables or step up to 12/24-fiber for redundant rings). Datacenter storage replication links where a NAS at site A mirrors to site B over dedicated dark fiber — 2-fiber simplex is enough for one-way rsync or CDP replication at 10 Gbps sustained. When pulled through 3/4-inch ENT conduit or laid in open cable tray alongside copper bundles, the yellow jacket stands out visually during troubleshooting, and the G.657.A1 spec tolerates the tighter bend radii inevitable when routing around HVAC ducts and structural steel.

Field termination flexibility: 900µm buffered fibers accept Panduit's FSTLC and FSTSC field-installable LC/SC connectors (mechanical splice, no fusion required, ~5 minutes per connector), or you can fusion-splice to factory-made pigtails using a Fujikura 70S or similar alignment splicer (typical splice loss 0.05-0.15 dB). For permanent installations, fusion splicing into a 12-port LC panel gives you the lowest insertion loss; for temporary or movable links, mechanical connectors trade 0.2-0.3 dB higher loss for tool-free field changes. Either way, the tight-buffered construction means you're working directly with the 900µm fiber — no need to strip back loose-tube gel-filled buffer and sleeve individual 250µm strands like you would with OSP cable. Panduit's Opti-Core product line shares consistent color codes, buffer dimensions, and jacket markings across 2/4/6/12/24-fiber counts, so your termination process and tooling stay the same whether you're pulling a 2-fiber camera drop or a 24-fiber building riser.
