We have developed two femtosecond laser frequency combs (FLFCs) employing different designs and no external spectral broadening devices. The FLFCs referenced to a microwave standard were directly compared and confirmed to have a relative fractional uncertainty of $8.1 \times 10^{-17}$ mainly due to imperfection in our comparison technique. They have also achieved uninterrupted daily operation typically more than 8 hours. They are found to be suitable for the optical standards from the absolute frequency measurement for a clock transition of 40Ca+ ions, that was recently performed in National Institute of Information and Communications Technology.
