Bought a CM3000 modem but my xfinity fiber has no Coax cable

[SID2099]

I purchased a Nighthawk CM3000 standalone modem and am trying to hook it up, but my Xfinity high speed fiber service has no coaxial cable to hook to it.

It has a power cable to the outside unit and a cat cable that provides the internet signal.

Is it possible to use the modem with this system? It said it was compatible with Comcast high speed.

IF the ISP only has Fiber to your home and no Coax, then you'll need to return the CM modem to place of purchase and ask the ISP about Fiber to Ethernet solution then connect up your wireless router system.
