Fibre Optic Telephone & Internet Service

Real fibre service to your doorstep

With MNSi’s new fibre optic Telephone & Internet Service, you’ll have access to the most advanced, high speed, all optical network in Windsor. With crystal clear telephone quality and Internet service with the fastest download and upload speeds available, you’ll be able to enjoy the best that the Internet has to offer without the wait...

Select neighbourhoods in Windsor have already been fitted with MNSi's own high speed fibre optic infrastructure, with more being upgraded soon. Unlike the cable company's "hybrid fibre" which still uses the same old fashioned copper coaxial cable technology, or the phone company's "fibre to the node" service which still uses yesterday's copper phone lines, MNSi's advanced network will run an actual fibre optic line right into your home.

* Terms and conditions apply. See the pricing page for more details.
