Where fiber optic cables are used

How we build them

Our fiber lines terminate and polish LC, SC, and ST connectors and test every assembly for insertion and return loss — OS2 single-mode and OM3/OM4/OM5 multi-mode, simplex or duplex, in the jacket and boot your run needs. MPO/MTP breakouts and pre-terminated trunks (Base-8 and Base-12 polarity) are built to your drawing, with your part number and packaging for private-label programs.

Fiber optic cables — common questions

Single-mode or multi-mode fiber?

Both — OS2 single-mode for long-haul and OM3/OM4 multi-mode for data-center and in-building runs, simplex or duplex.

What connectors and polishes do you offer?

LC, SC, and ST in UPC or APC polish. APC (angled) is used where low back-reflection matters, such as PON and RF-over-glass.

Are the assemblies tested, and to what standard?

Yes — end-face geometry and insertion and return loss to Telcordia GR-326, with test data per assembly and RoHS.

What is the difference between OM3 and OM4?

Both are laser-optimized multi-mode; OM4 carries the same data rate farther — a longer reach at 10G, 40G, and 100G. Tell us the distance and rate and we spec the grade.

Can you build custom fiber assemblies?

Yes — custom length, connector, polish, and jacket, with origin documented per unit.
