BroadR-Reach® PHYs

Innovative BroadR-Reach® technology extends the range of twisted pair connections from 100 meters to up to 500 meters. Designed to comply with CCSA specifications for a reach-extended Ethernet physical layer, these devices also offer interoperability with 10BASE-T, 100BASE-TX, and 1000BASE-T through a common RJ-45 interface.

BroadR-Reach also enables full-duplex operation over a single twisted pair, so that Ethernet and IP services can now be deployed at 100Mbps over installed telephone wiring. Additionally, BroadR-Reach is compatible with Power over Ethernet, greatly expanding the range of applications for POE appliances.
