ZTE Olt + CCR1009-8G-1S-1S+ SFP problem

Hello all,
I have problem with CCR and ZTE olt comunication using SFP.
Problem is that after turn of or power cut, ZTE and CCR not connected. I need disable and enable SFP and vlan to return comunication.
What can be the problem?

I use ZTE SFP in ZTE Uplink and same SFP in CCR.

SFP module is WXTRPGEAS1G. Photo is there too.
