The problem is that my custom map covers very small piece of territory and not included parts are sent like white empty image and I do not see base layer. I've used setOpacity method for layer to set opacity of my layer to 0.5 so I can see the base layer. But maybe it's possible to configure kind of transparency in my layer ? To tell Open Layers that white color should not be rendered at all ?

Probably a WMS Layer? set transparent: 'true' in your WMS params (third
arg); and make sure your images can be served as 'not jpeg'.
