The FC patch cable is the "rugged specialist" of fiber connectors. Its threaded design makes it slower but supremely stable, securing its ongoing role in precision test laboratories, harsh industrial settings, and legacy telecom networks, even as smaller connectors dominate new installations in data-centric environments.



Primary Usages and Applications

1. Test & Measurement and Laboratory Equipment
2. Telecommunications & Outside Plant (Historical & Legacy)
3. Industrial Automation & Harsh Environments
4. High-Power Optical Systems
5. Broadcast (Legacy and Specific Applications)

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.
