12-Fibers Singlemode 9/125 OS2 LSZH Indoor Ribbon Fiber Optic Cable

Description

12-Fibers Singlemode 9/125 OS2 LSZH Indoor Ribbon Fiber Optic Cable

Factory-fabricated 12-fiber singlemode indoor ribbon fiber optic cable designed for high-density data center backbone and ODF equipment room interconnects. The cable stacks twelve 9/125 µm bend-insensitive G.657.A1 fibers in a flat ribbon stack under LSZH jacket, ready for mass-fusion splicing with 12-fiber ribbon splicers or pre-terminated MPO/MTP connectors. Yellow jacket follows TIA-598-D OS2 color code, and the cable is fully compliant with IEC 60332-3, IEC 60793, and Telcordia GR-409-CORE indoor cable standards.

Key Features

• 12-fiber ribbon stack: mass-fusion splices in 1 minute vs 12 individual splices, ideal for high-density data center backbone builds.
• Bend-insensitive OS2 fiber (G.657.A1): 7.5 mm minimum bend radius for tight routing inside cable trays and ODF frames.
• LSZH yellow jacket: flame-retardant OFNR-rated, low-smoke zero-halogen compliant with IEC 60332-3 for plenum and equipment-room use.
• High-density scalability: stackable from 12 fibers up to 864 fibers by ribbon stacking (24/48/72/96/144/288/432/576/864 cores available on request).
• Pre-terminated options: ships on reel or pre-terminated with MPO/MTP connectors (Base-8/Base-12) at one or both ends.
• Standards compliant: IEC 60793-2-50 B1.1 (OS2 singlemode), IEC 60794-1-2, Telcordia GR-409-CORE indoor.

Applications

• Data center backbone interconnects between ODF frames and equipment rooms
• Hyperscale spine-leaf and intra-building fiber runs
• Mass-fusion splicing for high-density distribution frames
• Pre-terminated MPO/MTP trunk cable raw material (12-fiber ribbon based)
• Central office and telecom equipment room fiber distribution
• FTTH feeder and riser backbone cables in MDU/MTU deployments
