Frequently Asked Questions
Why is fiber faster than cable?
Fiber uses light through glass cables (speed of light). Cable uses electrical signals through copper (much slower).
Is fiber worth the extra cost?
Yes if you work from home, stream 4K, or upload large files. No if you just browse and check email.
Can I upgrade from cable to fiber?
Only if your ISP offers fiber in your area. Check their website or call.
