The differences between Single-Mode Fiber (SMF/OS1/OS2) and the various Multi-Mode Fiber (OM1, OM2, OM3, OM4,OM5) grades.
Grade | Core Size | Jacket Color | LED-Optimized | Laser-Optimized (850nm VCSEL) | Key Feature & Typical Use |
SM | 8-10 µm | Yellow | \ | \ | Long-distance: Telecom, ISP backbones, CATV, MANs (10s to 1000s of km). |
OM1 | 62.5 µm | Orange | 200 MHz·km | Not supported | Legacy installations (1990s). Limited to 1 Gigabit up to ~275m. |
OM2 | 50 µm | Orange | 500 MHz·km | Not supported | Basic 1 Gigabit Ethernet up to ~550m. Being phased out. |
OM3 | 50 µm | Aqua | Not primary | 1500 MHz·km | First laser-optimized (LOMMF). 10 GbE up to 300m. Standard for modern 10G data centers. |
OM4 | 50 µm | Aqua | Not primary | 3500 MHz·km | Enhanced OM3. 10 GbE up to 400m, 40/100 GbE up to 150m. High-speed data center backbone. |
OM5 | 50 µm | Lime Green | Not primary | 3500+ MHz·km (but optimized for Short-Wavelength Division Multiplexing - SWDM). | Designed for multi-wavelength transmission (e.g., 40G-SWDM4). A single OM5 pair can carry multiple wavelengths, reducing fiber count for 40/100/400G. |
