Fiber optic transmission supports the longest distances and highest data rates of any communications infrastructure. Long used in backbone networks such as SDH/SONET, fiber has spread from the core to the metro area network (MAN) and into the first mile. Additional benefits of fiber include data security and immunity to interference.

RAD is a leader in integrating fiber solutions into a broad range of access products. Its solutions include fiber extension, fiber optic modems, fiber optic multiplexers, voice and data integration, ATM service distribution, point-to-point campus applications, utility applications and TDMoIP (transport of TDM circuits over IP networks).

RAD’s Resilient Fast Ethernet Ring (RFER) technology introduces self-healing capabilities to provide protection on 100 Mbps Fast Ethernet fiber or copper rings.

This unique technology is implemented in the new ML-IP module for Megaplex multiplexers. In case of link failure on any segment of the ring, RFER reroutes the traffic within 50 milliseconds.
