Narad Networks has unveiled its EtherNode switched HFC architecture, which is based on outdoor Ethernet switches.

The Narad Ethernet switch distributes high-capacity, high-performance Ethernet directly to customers over any available medium, including fiber, coax, or wireless.

For example, in cases where business fiber or metro fiber passes near the end of a coax trunk, Narad EtherNodes can switch optical Ethernet capacity onto coax trunks with minimal (perhaps even zero) plant downtime.

Where fiber construction is expensive or problematic, MSOs can leverage existing coax to avoid new plant construction, while at the same time, reaching business customers with high-performance Ethernet and high-capacity voice applications, the company said.
