The question is a bit fuzzy (to me anyhow), but if it is listed as "9 (or 8.3)/) it's single mode fiber.
If it has "50/125" or "62.5/125" printed on the jacket, it's multi-mode fiber.
There are other sizes (especially for MM), but 50/125 and 62.5/125 are the most common, with 50/125 becoming more popular with the rollout of GigE over multi-mode.
Single mode also tends to be in a Canary Yellow jacketing, while multi-mode is frequently orange, but also comes in grey, black, and possibly other colors.
Single mode can carry more bandwidth farther without amplification. As a single bandwidth carrier, it commonly goes up to ~10Gig (OC192, 10Gig Ethernet) but could carry more.
As a carrier of a Wave Division Multiplexed (WDM, including Dense WDM - DWDM) signal, Single Mode can carry much more .... up to 64 channels, each channel carrying 2.4Gig to 10Gig (specs vary with the manufacturer of the WDM / DWDM).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
