Premium fiber and the Fiber Builder

Choose from our premium Corning cables, or build a custom cable to your exact spec.

Premium fiber optic cable
Premium fiber

Unmatched quality, designed to run your network at the highest performance: Corning® ultra-pure glass fiber for strength and low signal loss, a Low Smoke Zero Halogen (LSZH) jacket for the safest cabling environment, and bend-insensitive fiber for excellent transmission in challenging environments.

Customize your own fiber optic cable by choosing the connector type, cable type and length.

Premium cable: speed, safety, reliability, growth

What goes into every CablesAndKits premium fiber cable.

Corning optical fiber glass

Corning ultra-pure glass fibers give the highest degree of strength and purity, for low attenuation and low signal loss across your network.

Bend-insensitive fiber (BIMMF)

Our premium OM3 cables transmit light with minimal loss even when bent and twisted beyond the normal bend radius. A ring of refractive material reflects escaping light back into the core.

LSZH jacket material

Low Smoke Zero Halogen jackets reduce the toxic and corrosive gas that could be released under extreme heat or in a fire.

Ultra Physical Contact (UPC) polish

Lower Optical Return Loss and back reflection than standard PC connectors, for more reliable data, digital and telephony signals.

Simple reversible polarity

Reverse polarity on our OM3 cables in the field, without special tools, for correct fiber mapping with fewer cables.

2.0mm unibody cable

A 2.0mm footprint, compared with 3.0mm for regular fiber cables, for better airflow, cooling and cable management in dense racks.

Fiber basics

What is a fiber patch cable?

A fiber cable is a patch or interconnect cable that uses glass instead of copper to carry the signal. Its three main parts are the core, the cladding and the jacket.

Fiber basics

What are the differences between the optical modes?

The two big differences are core size and transmission. OM1 uses a 62.5/125-micron core while the rest use a 50/125-micron core. OM1 and OM2 use LED transmitters, while OM3, OM4 and OM5 use laser-optimized multimode transmission.

OM5 at a glance

The benefits of running OM5 fiber in your network.

Compatibility

Backwards compatible with OM3 and OM4, so you can upgrade without replacing older cables.

Distance

Up to 440 meters for 40G networks and up to 150 meters for 100G.

Affordability

A serious increase in performance without a serious increase in price.

Higher bandwidth

More bandwidth from a single fiber: 28 GHz.

Lower fiber loss

OM5 needs fewer fibers and can use four separate wavelengths, so loss is lower.

Wideband multimode fiber

WBMMF extends OM4 to carry multiple wavelengths, supporting traffic from 850 to 950 nm.

OM5 vs OM4

OM5 gives you all the benefits of OM4, plus longer runs on SWDM4. Distance comparison:
