My query is where should be placement of ac coupling capacitor in sgmii interface on PCB??? What should be the value of ac coupling capacitor???
 

Sounds like you connected SGMII Device in CDR mode, so in that case you have to place AC coupling Caps near receiving end.

The values for Caps is depend on the length of differential signals (10nF to 100nF) for better termination.
