Narad Flips Switch on 100-Mbps Service

Narad Networks unveiled a new Ethernet switch that it said can funnel 100 megabits per second simultaneously to every cable home.
In development for nearly five years, the new modular Ethernet switch can be geared to serve commercial or residential customers with a variety of connection speeds in fiber-to the premise or fiber-the-curb configurations. For high-capacity residential broadband, the switch can be used in fiber-to-the-curb network designs, imitating passive optical network (PON) systems but at a lower cost, according to Narad.
For fiber-to-the-curb applications, the Narad switches can be placed at existing coax cable taps where the fiber meets the coax connection to the customer. Broadband Ethernet connections coming from the fiber network are fed into the Narad modular tap switch, where an internal modem converts the Ethernet signal into modulated radio-frequency signals at frequencies above existing cable services. The Narad switch then delivers that bandwidth plus the cable TV signals to the home, where a Narad modem supplies up to 100 Mbps symmetric bandwidth to the home router or computer. The parallel cable TV signals, meanwhile, move over the in-home coax to TV sets.
And at 100 Mbps per customer, these systems will provide greater bandwidth than what Verizon’s FiOS or AT&T’s Project Lightspeed fiber networks can supply, according to Narad CEO Michael Collette.
“With this new platform, cable operators can future-proof their network to support more advanced services by delivering higher capacity at lower costs and in less time than anything offered by Verizon or AT&T,” he said.
