This laser-optimized multimode fiber (LOMMF) cable provides backward compatibility with existing 50/125 equipment while providing the performance headroom required to support laser light sources and 10 gigabit applications. Optical Multimode 3 (OM3) fiber supports 2000 MHz/km EMB at 850nm, and provides 10 gigabit transfers up to 300 meters using an 850nm VCSEL source. This cable also provides the fire protection required to run within walls and air plenums without the need for conduit; the Low-Smoke Zero-Halogen jacket protects from toxic and corrosive gases in poorly ventilated spaces and other areas where it is most critical.
