How to couple light from an LED source to a single mode fiber? Is there LED source available with FC/PC connector at wavelengths 1550nm and 850 nm?

I need this at wavelength 1550nm and 850nm. I have LED source already, but it is with SMA connector. I tried using SMA/FC converter, but it did not work.
