摘      要：We demonstrate a 300-km+200-km cascaded coherent phase transfer via fiber *** transfer is divided into a 300-km span and a 200-km span with independent phase locking loops,aiming to extend the phase control bandwidth of the whole *** phase noise and transfer instability of the cascaded transmission are investigated and compared with those in the case of a single-span 500-km *** achieve the transfer instabilities of 1.8×10^-14 at 1 s,8.9×10^-20 at 104 s for the 300-km+200-km cascaded transmission,and 2.7×10^-14 at 1 s for the 500-km single-span transfer.
