Thorlabs multimode, graded-index, polymer, optical fiber (GI-POF) from Chromis Fiberoptics is characterized by low attenuation and low material dispersion, thus allowing it to support high-speed Gigabit Ethernet or multigigabit applications up to 100 m or Fast Ethernet connectivity up to 200 m.

GI-POFs combine the ease of use associated with plastic optical fibers with the low loss, low dispersion, and good transmission characteristics typical of glass fibers at 850 nm and 1300 nm. Moreover, these fibers can sustain long-term bending radii as small as 5 mm, which exceeds the capabilities of glass fibers with the same core size.

GI-POF fiber is simple to terminate and the end face can be polished quickly to produce a low-loss connection. In addition, these fibers do not require special adapters in order to mate them with like core sized glass equivalent devices. Consequently, GI-POF is a direct drop-in glass fiber replacement alternative that offers a significant cost advantage.
