Manufacturing Optical Fiber
The manufacturing of optical fiber to sub-micron precision is an interesting process involving making ultra-pure glass and pulling it into strands the size of a human hair. The process begins with the manufacture of a preform, a large diameter glass rod which has the exact same optical cross section as a fiber but is hundreds of times larger. The end of the rod is heated and a thin strand of fiber is pulled from the perform and wound on large reels. After manufacture, the fiber is tested and then made into cable.

Fiber Sizes and Types
Fiber comes in two types, singlemode and multimode. Except for fibers used in specialty applications, singlemode fiber can be considered as one size and type. If you deal with long haul telecom or submarine cables, you may have to work with specialty singlemode fibers.
Comparison of core/cladding sizes
Here is another way to look at fiber - The Optical Fiber Family Tree
For information on what all the different designations mean, see the table below or go here.
Multimode fibers originally came in several sizes, optimized for various networks and sources, but the data industry standardized on 62.5 core fiber in the mid-80s (62.5/125 fiber has a 62.5 micron core and a 125 micron cladding. It's now called OM1 standard fiber.) Recently, as gigabit and 10 gigabit networks have become widely used, an old fiber design has been revived.  50/125 fiber was used from the late 70s with lasers for telecom applications before singlemode fiber became available. 50/125 fiber (OM2 standard) offers higher bandwidth with the laser sources used in the gigabit LANs and can allow gigabit links to go longer distances. Newer OM3 or laser-optimized 50/125 fiber today is considered by most to be the best choice for multimode applications. OM4 fiber is a higher bandwidth fiber for 10G+ networks. OM5 is wideband multimode fiber optimized for wavelength division multiplexing with VCSELs in the  850-950nm range.
To identify the types of fiber in a cable, there are standardized color codes for the cable jacket covered under TIA-598. Here is more information on color codes for cables and connectors.China GYFXY 6 Core Fiber Cable
