Faster Internet speeds will be an option for some Silverdale businesses early next year when Comcast finishes work on its new fiber-optic network.

The network will run in a loop along Silverdale Way, Myhre Road and Bucklin Hill Road according to Steve Kipp, Comcast spokesperson for Washington. It is expected to be finished in early 2015.

“When completed, we will be able to serve approximately 550 businesses in the area,” Kipp said.

The network will be capable of transmitting data at speeds as fast as 10 gigabits per second. That’s equivalent to 1,250 megabytes, or about as much data as two compact discs can hold.

In contrast to copper-based wiring that sends signals via electrical pulses, fiber-optic lines work by sending pulses of light through glass fibers.

Kipp said Silverdale was “underserved” by fiber-optic networks and said additions to the Harrison Medical Center Silverdale campus and the overall growth in the area were factors that spurred the project.

“We think it’s going to be a really great growth area for us,” he said.

The Old Town section is one of the final phases of the project.

Construction workers with Full Bore, Inc., used trenchless drilling equipment to drill bore holes horizontally underneath the streets by using a steerable drill bit. They’ll pull plastic conduit through the holes.

The project began last year. Kipp said Comcast spends about $30 million annually on Puget Sound-area network projects.

“We’ve got thousands of miles of fiber in the state of Washington and we’re building more fiber every day,” Kipp said.
