Yes. Go to http://www.newarkinone.com they have everything, and good sales
support for the gidget gadget world.
Your not trying to make one of them there chea pet lighted heads are
you.....
I did have a reel of 8 pair single mode fiber, but the reel wouldn't fit in
my rental car, so I left it in Wyoming on the jobsite.

I don't want any mount, no shoulder flange, nutthin special...at least for
my mock up. It has to fit in very small space, so I'm just gonna hot glue
them into small opening for the prototype.

Patch cord's too expensive considering that I'm only after the bare fibers
inside the jacket.

Does your parts supplier have a website with the leds listed?...most
online's don't have the little stuff online.
