(1) check the optic cable, the optical fiber has two terminals:TX and Rx which need to corresponding to the module's TX and RX

(2) try to force speed 1000 and duplex full on both sides

             Ruijie(config)#interface gi 0/24

             Ruijie(config-if)#speed 1000

             Ruijie(config-if)#duplex full

(3) If used third brand fiber module, try to change with Ruijie fiber module.
