What's the difference between OM3 and OM4 fiber optic cable?
OM3 and OM4 are types of laser-optimized multimode fiber, with OM4 being an enhanced version of OM3, offering significantly higher bandwidth and longer reach for high-speed data, especially for 40/100 Gb Ethernet; OM4 supports 10GbE up to 550m, while OM3 supports it to 300m, with OM4 being ideal for future scalability despite a slightly higher cost. Both share the same aqua jacket but OM4's superior Effective Modal Bandwidth (EMB) of 4700 MHz·km (vs. OM3's 2000 MHz·km) allows for lower signal loss over distance, making it better for data centers and longer runs.
Key Differences
- Performance: OM4 has double the modal bandwidth of OM3, allowing longer link distances for high-speed applications like 10G, 40G, and 100G Ethernet.
- Distance: For 10GbE, OM4 reaches 550m, while OM3 reaches 300m; for 40/100GbE, OM4 does 150m, whereas OM3 only does 100m.
- Bandwidth: OM4's EMB is 4700 MHz·km; OM3's is 2000 MHz·km (both at 850nm).
- Cost: OM3 is generally more budget-friendly and sufficient for shorter, less demanding networks, while OM4 costs slightly more but offers better future-proofing.
- Compatibility: OM4 is backward compatible with OM3.

When to Choose Which
- Choose OM3 for:Cost-effective, shorter-distance LANs where 10GbE up to 300m is sufficient, and future high-speed needs are minimal.
- Choose OM4 for:Data centers or longer runs requiring 10GbE beyond 300m, or for 40/100GbE, providing greater scalability and future-proofing for network upgrades.

How tight can you bend fiber optic cable?
The normal recommendation for fiber optic cable is the minimum bend radius under tension during pulling is 20 times the diameter of the cable (d).
