Corning MIC® Tight-Buffered Plenum Fiber Optic Cable — 48-Fiber OM1
The Corning 048K88-61130-29 is a 48-fiber MIC® (Multiple Interconnect Cable) tight-buffered plenum fiber optic cable designed for indoor backbone and horizontal runs in commercial buildings, data centers, and enterprise networks. It carries an OM1 multimode rating with 62.5/125µm glass fiber, delivering reliable Gigabit Ethernet and legacy multimode network performance.
Key Features
- OM1 Multimode — 62.5/125µm: Optimized for 850nm and 1300nm LED sources; supports Gigabit Ethernet and legacy multimode protocols across short to medium indoor runs.
- TBII® 900µm Tight-Buffered Fibers: Corning’s TBII® buffered fiber construction provides consistent, easy stripping for field termination without special tools or pre-stripping jigs.
- All-Dielectric Construction: No metallic elements — no grounding or bonding required. Ideal for runs between buildings or in electrically noisy environments.
- Plenum-Rated Jacket: Orange, flame-retardant outer jacket meets NEC Article 770 OFNP (Optical Fiber Non-conductive Plenum) requirements for installation in air-handling spaces without conduit.
- MIC® Cable Design: Corning’s proven MIC architecture provides a rugged, durable structure that resists crushing and kinking during installation in conduit or cable trays.
- 48-Fiber Count: High fiber density in a compact diameter — ideal for backbone risers, campus backbones, and high-density patch rooms where multiple circuits must be consolidated.
