GigaPOF-120LD is a revolutionary POF offering high performance and unmatched simplicity in a single package. With instant termination, relaxed optical alignment tolerances, and excellent IR and visible transparency, no other multi-gigabit medium is as easy to use.

GigaPOF 120SR


Graded-index perfluorinated POF: combining the best of the glass fiber and plastic fiber worlds

Until now, the simplicity of plastic optical fiber came with a heavy price: low performance and a restriction to visible wavelengths. The Chromis GigaPOF® line overcomes that trade-off with low attenuation, IR-transparent polymer materials, a graded refractive index, and exacting geometric tolerances. GigaPOF-120LD easily supports Gigabit and 10-Gigabit Ethernet, HDMI, USB 3.0 and other multi-gigabit applications at distances up to 100 meters without dispersion compensation.

A versatile performer

GigaPOF-120LD meets the need for a multi-gigabit fiber that can be used with large alignment tolerances. The 120-mm core and strong mode coupling of this fiber allow an input offset tolerance of more than 30 microns, but it still couples well to most high-speed detectors.

Like the rest of our GigaPOFÒ line of optical fibers, GigaPOF-120LD can be factory-terminated in seconds with our automated tool, and can be clamped or glued directly into optical sub-assemblies without a ferrule. For field-installable applications, very simple crimp-on connectors and inexpensive tools, make it the easiest-to-install high-speed medium in the world.

Unequaled speed and flexibility

GigaPOF-120LD not only has a qualitatively higher bandwidth than other large-core optical media, but it can be used over a wavelength range from 780-1310 nm. No other gigabit optical medium offers this combination of simplicity and versatility.
