Trade surpasses religious barriers oftentimes. Vikings had offered service to the Byzantine courts presumably sailing down the rivers from the north, or round the coast. Maybe one of them brought something back north, and it wound up moving around in north europe. Walrus ivory would have been a valuable counter-trade going south, or Amber.

As I understand it, the Silk Road only became important when the sea route was closed. It lost its importance 800 years later when the Portugese found the sea route around Africa.
But it's equally likely they traded indirectly with any of the coastal economies around the Gulf, and Horn of Africa.
Interesting and makes sense to me. I remember reading a long time ago, when the Eastern Empire lost Egypt to the Arabs, it was considered a huge major disaster for them.
"Väringar"[0], traded, traveled, and fought from the Baltic to the Mediterranean sea. And they most certainly brought a lot back home.
