Various fiber optics links are evaluated for the transmission of OCXO signals on relatively short distances (1 m to 1 km). The case of VCSEL lasers is compared to the case of the more classical DFB laser. The DFB is still the best device, particularly in terms of signal to noise ratio, but single-mode VCSELs are becoming interesting as a low cost alternative to this device.
