CCR 1036 WAN 10G does not detect link at Rx loss of 12 db

CCR 1036 WAN 10G does not detect link at Rx loss of 12 db.

The ISP fiber is SM 10G getting connected to Mk 10G SFP+ port. Assigned IP as well but not detecting link.

Rx showing a loss of 12-13 db. SFP module is also 10G SM.

ISP is asking make port on WAN mode… Now whats that?

Pls suggest.
