We present two cavity-stabilized lasers at 1555nm,which are built to be the frequency source for a transportable photonic microwave generation system.The frequency instability reaches the thermal noise limit (7 × 10-16) of the 10-cm ultra-low expansion glass cavity at 1-10s averaging time and the beat signal of the two lasers reveals a remarkable linewidth of 185 mHz.
