More than 99.9% of the optical fiber manufactured in the entire world is all the same diameter, 125 microns. Some of it is single mode and some is multimode, but all of it has a 125 um clad diameter. This fiber size dominates the high volume communications applications: telephone (including the ever-expanding mobile networks), cable TV, broadcasting and data communications (data centers, private networks, in-building and campus networks).
That leaves something less than 0.1% of the world fiber output, which ranges in diameter from 80 to over 2000 microns, and is considered specialty fiber. In general, these fibers are not used for communications, but rather for other applications: research, sensing, laser delivery, medical, military, utilities (oil and gas explorations and production, including downhole and undersea), spectroscopy, industrial and others.
For over 20 years, FOC has focused on this specialty fiber market, stocking connectors for more fiber sizes than any other company in the world, and by understanding many of the issues faced by users of these fibers. FOC maintains an inventory of more than 40 hole sizes of SMA connectors, along with about 10 sizes of FCs. We also offer custom hole sizes (i.e., other than 125 um) in ST, SC, LC and other connectors.

Having a variety of whole sizes in stock has advantages to people considering the use of a novel or unusual fiber, as well as to those already committed to using these fibers, including:
1. No minimum dollar value for connectors in stock.
2. No engineering or tooling charges, or minimum order quantities for existing or new hole sizes.
3. A stable price over many years; no rude surprises after choosing novel fiber diameters.
4. Immediate delivery for small to moderate quantities, enabling quick proofs of concept and rapid delivery of prototypes.
5. Stock in large volumes for production programs, without the expense of keeping inventory in-house.
6. A knowledge base over many years dealing with manufacturers and users of specialty fibers.
Familiarity with special coatings and cable constructions that are often required when using non-standard fibers
