What fiber types do you support?

OM3, OM4, OM5 multimode and OS2 singlemode. All available in custom lengths with LC, SC, and MPO/MTP connectors.

Do you make custom fiber lengths?

Yes, in 3-inch increments. Tell us your rack geometry; we engineer to the exact slack required, no wasted cable.

What's the difference between OM3, OM4, OM5, and OS2?

OM3/OM4/OM5 are multimode (short reach, 100-550m). OS2 is singlemode (long reach, kilometers). OM5 adds WDM. OS2 is the AI/HPC default.

Do you factory-test fiber cables?

Every cable. We provide IL/RL certification per fiber with the shipment, including OTDR traces on long runs.

What connectors are available?

LC, SC, MPO/MTP-12/24/32, and CS. Polish: UPC standard; APC for parallel singlemode (DR/PSM/SR8.2 BiDi).

OM3 vs OM4 vs OM5 vs OS2 — pick the right fiber

Multimode vs singlemode is the first decision. Within multimode, OM4 is the workhorse and OM5 adds SWDM. OS2 is the AI/HPC default for anything beyond a single rack row.
