Google Fiber Contemplates Renewing Expansion with Google “SuperPON” Fiber Architecture

Google may be considering renewing expansion of its fiber to the home networks with a new technology that can extend network distances and cut costs.

Telecompetitor reports Google’s “SuperPON” architecture can support up to 1,024 customers over a distance of as much as 50 kilometers, dramatically reducing the costs to lay fiber and build central switching offices to manage connections across a metro area.

Current passive optical networks (PON) can support only 64 customers over a distance of up to 20 kilometers, which means companies have to lay cables with a larger bundle of optical fibers and construct as many as 16 central offices in each metro area to support its operations. If Google can manage to reduce the size of the cable, as it can using SuperPON technology, the company can bury fiber cables using microtrenching, which costs much less than traditional buried conduit.

As a result of improved amplification technology, Google can reach many more customers over a much larger distance using a            single strand of fiber, and offer each customer as much as 10 Gbps broadband. The SuperPON technology appears to be based on Google’s Go-Long network concept, introduced in 2017.

Claudio DeSanti, an architect for Google, told an audience at the Adtran Connect conference that Google has already deployed its SuperPON technology in one unspecified Google Fiber market, and the cost savings achieved could allow Google to return to fiber broadband buildouts. Google effectively paused its fiber expansion effort in late 2016 after examining the costs and the competitive impact of cable and phone company incumbents upgrading their own services to compete with Google. To be economically feasible, a new entrant must capture a certain percentage of market share to pay off network construction costs and be seen as economically viable. Google can either grow market share or reduce the costs of network construction to keep Google Fiber tenable.

DeSanti claims reducing cable size is not only less costly, it also results in higher reliability and an easier ability to repair damaged cables. Construction and labor expenses would also be slashed because Google’s SuperPON technology only needs an average of three central offices in a metro area, down from 16 or more using traditional PON technology. DeSanti hopes the SuperPON architecture will become an industry standard, which would reduce costs further through mass production of cables and construction equipment.

After Google pulled back from its fiber expansion project, the company turned towards fixed wireless services in urban areas and multi-dwelling units, which is ongoing.
