The only way to offer a Gig over copper

As service providers compete to serve the vast numbers of people living in MDUs, they are seeing an increased demand for gigabit services. While many offer gigabit services to FTTH single-family units (SFUs), the push to offer similar services to the MDU has not been universal.

Today, subscribers in apartments feel dissatisfied that the gigabit experience is not available to them, and typically it requires the service provide first bring fiber to the building – a costly business case to make.

But could they offer that same gigabit experience reliably over the existing MDU copper infrastructure?


While a single pair G.fast solution can offer theoretical speeds of up to 900 Mbps, this is really only under perfect conditions, with unrealistic short loop lengths that exist only in a small portion of MDUs. All vendors like to market the best performance possible, but those speeds cannot be guaranteed to all subscribers, given the wide variety of MDUs and the age of existing copper infrastructure inside the building.

Speeds will vary based on copper quality, loop lengths, noise interference, and in-building copper architecture, which results in average speeds closer to 600-700 Mbps asymmetric – not gigabit.

To meet the need for a full 1 gigabit experience, Calix has led the market by delivering the ONLY two-pair bonded G.fast solution. This means you can now break through the gigabit barrier for all subscribers in copper served MDUs, and still deliver the upstream and downstream that subscribers demand. Speeds of up to 1.5 Gbps to each apartment!

Now you can deliver the exact same services over copper as you would to a FTTH subscriber!

Here’s just one example of how service providers are deploying G.fast to offer gigabit services to beat their MDU competition.
