While the majority of graded-index fiber is all glass, there are some GI POF fibers also.

Singlemode Fiber

Singlemode fiber shrinks the core down so small that the light can only travel in one ray or mode, hence the name singlemode.

SM fiber animation

Since there is only one mode, there is no problem with modal dispersion and the choice of core material can reduce chromatic dispersion (see below) which increases the bandwidth to almost infinity - but it's practically limited to about 100,000 gigahertz - that's still a lot! Singlemode fiber has a core diameter of 8-10 microns, specified as "mode field diameter," the effective size of the core, and a cladding diameter of 125 microns.

Specialty Fibers have been developed for applications that require unique fiber performance specifications. Erbium-doped singlemode fibers are used in fiber amplifiers, devices used in extremely long distance networks to regenerate signals. Fibers are optimized for bandwidth at wavelengths appropriate for DWDM systems or to reverse chromatic dispersion. This is an active area of fiber development.

Bend Insensitive Fibers

Optical fiber attenuation is sensitive to stress like encountered when bending fiber too tightly, especially with patchcords and fibers in tight enclosures. Stress causes light to exit the core of the fiber causing loss. A modification to the fiber index profile, adding a low index layer of glass around the core, usually called an optical trench, that guides or reflects light lost from the core back into the core can make fiber much less sensitive to bending losses. This can be done with both multimode and singlemode fibers.
