At minimum, I think you should probably specify the type and number of 
fibers you want.  i.e. Based on the distance and gear you'll be using, do 
you need single-mode, or will multi-mode do (as well as the core/cladding 
diameter)?  Generally, but not always, fiber uses one strand for transmit 
and another for receive, so a typical fiber run is done using duplex 
fiber.  Some optics can transmit and receive over one strand using 
different wavelengths.  You might even specify how you want the fiber 
terminated (SC, LC, cables hanging from the wall, fiber patch panel, 
etc.).
