Benefit
• 2-15 Mbps bandwidth over category 1/2/3/5 single-pair copper wiring over distances up
to 5,000 feet.
• Profiles available for optimizing upstream and downstream bandwidth requirements:
(Actual achievable data rates depend on cable quality, noise and cross talk
environment.)

• Rate selection automates the process of selecting a profile that is optimal on a given
interface thereby greatly improving the ease of installation and optimizing the
bandwidth for a given environment. Profiles are grouped into sequences that can be
configured by the customer.
• Flexibility to use either 10BaseT/100BaseTX/1000BaseT autosensing ports, or SFPs for
fiber connectivity to support LRE switch daisy-chaining, aggregation or server/router
connectivity.
• Full-duplex operation on all ports, delivering up to 15 Mbps symmetric on LRE ports
and up to 1000 Mbps symmetric on 10/100/1000 and SFP ports.
