Does Xfinity offer true Fiber Internet in Parker, Colorado 80134

I currently have xFinity cable internet and it's horrible.   
What I have under contract is 1GB but the true speed is about 300-500 mbps.   
Usually I only have about 30% of 1GB data.  There are technicians came to my house but they admitted they cannot fix the issue because of cable internet.    I am using Xfinity brand router/Wifi and it's still horrible.  

We all know Cable internet is horrible and unreliable compare to  true fiber internet like  AT&T, BAM....etc..

Does Xfinity offer  "true fiber"  internet connect to my house in Parker, Colorado,  Zip 80134 ?  
If no, does Xfinity has plan to instal  true-fiber in Parker area like AT&T & BAM?
