4 Fibers 10G OM3 Indoor Cable – Frequently Asked Questions (FAQ)

1. What is OM3 multimode fiber used for?

OM3 fiber is optimized for 10 Gb/s high‑speed data transmission over short distances inside buildings and data centers.

2. How many fibers are inside the cable?

This version contains 4 tight‑buffered multimode fibers.

3. What does LSZH mean?

LSZH stands for Low Smoke Zero Halogen – it minimizes toxic emissions during fire, making it safe for indoor environments.

4. What is the maximum transmission distance for OM3 at 10G?

Up to 300 meters at 10 Gb Ethernet using 850 nm VCSEL laser sources.

5. Can this cable be used outdoors?

No, it is an indoor distribution cable; outdoor versions use PE or armored jackets.

6. What connectors are compatible?

SC, LC, ST, MTP®/MPO connectors can be terminated on OM3 multimode fibers.

7. Is the cable flame‑retardant?

Yes, the LSZH sheath meets IEC 60332‑1 flame resistance standards.

8. What color is the OM3 fiber jacket?

Standard color is aqua blue for OM3 classification.

9. What advantages does tight‑buffered construction provide?

It allows simple termination, better mechanical strength, and flexibility compared to loose‑tube designs.

10. Is 10 GbE backward compatible with 1 GbE?

Yes, OM3 fiber can support lower‑speed applications such as 1G or 100 Mb Ethernet as well.

11. What standard defines OM3 performance?

IEC 60793‑2‑10 defines OM3 multimode fiber core properties and bandwidth.

12. How is attenuation measured?

Measured at 850 nm and 1300 nm wavelengths using optical power meters; OM3 ≤ 3.0 dB/km at 850 nm.

13. Can the number of cores be customized?

Yes, versions from 2 core up to 24 core are available upon request.

14. Is MeFiberOptic cable compliant with EU safety regulations?

Yes, all cables meet RoHS and REACH requirements.
