| Acronym | Meaning |
|---|---|
| SM | Singlemode fiber (long-reach links; typically 9/125‑µm core/cladding). |
| MM | Multimode fiber (short-reach, high bandwidth; typically 50/125 or 62.5/125‑µm). |
| OS1 | Singlemode grade optimized for indoor/controlled environments (often tight-buffered indoor builds). |
| OS2 | Singlemode grade optimized for outdoor/long-reach links (lower attenuation; common for campus/backbone). |
| OM1 | Multimode 62.5/125‑µm (legacy indoor networks). |
| OM2 | Multimode 50/125‑µm (legacy/utility MM). |
| OM3 | Laser-optimized 50/125‑µm MM (common for 10G/40G/100G short reach). |
| OM4 | Higher-bandwidth OM3-class MM for longer short-reach data center runs. |
| OM5 | Wideband multimode supporting multiple wavelengths (SWDM) for expanded short-reach capacity. |
| OFNR | Optical Fiber Nonconductive Riser rating (vertical pathways between floors). |
| OFNP | Optical Fiber Nonconductive Plenum rating (air-handling spaces; low-smoke jacket). |
| I/O | Indoor/Outdoor rated (jacket suitable for both building entry and exterior pathways). |
| TB | Tight-buffered fiber construction (often used indoors; easier breakout/termination). |
| LT | Loose-tube construction (often used outdoors/backbone; fibers protected in tubes). |
| Armored | Added mechanical protection (metallic or dielectric armor) for crush/rodent resistance. |
| DB | Direct Burial (construction intended for burial/wet environments; confirm gel/water-block features). |
| UL | Underwriters Laboratories listing/recognition (safety compliance marking). |
