We have performed a multi-arm Er:fiber-based frequency comb comparison. The beat frequencies are simultaneously realized over 90 THz (from 192 to 282 THz) showing an integrated phase noise below 55 mrad (1 Hz-1 MHz) and an overlapping ADEV of 5x10-17 at 1s, averaging below 1x10-18 at 100s (PI-mode).
