Carrier Ethernet

Carrier Ethernet leader RAD Data Communications (News - Alert) has welcomed the newest member to its unique System-on-an-SFP family – the SFP-ER, a miniature Ethernet extender that delivers 100 Mbps of Ethernet up to 550m (1,804 feet) over existing copper wires (4-pair).

Housed in a Small Factor Pluggable (SFP) enclosure, the finger-sized SFP-ER is easily attached to any Ethernet switch with an MSA-compatible 100 Mbps TX Serdes, according to company officials.

“The SFP-ER will prove to be a welcome tool for system integrators, service providers and campus network managers because it lets them use the existing copper infrastructure for high-speed Ethernet while eliminating the expense of laying new fiber,” said Jacky Acoca, global business manager for Smart SFPs at RAD Data Communications (News - Alert).

“In addition, it has an advantage over VDSL because it is symmetric and also minimizes the need to purchase external VDSL boxes, saving space, reducing power consumption and cabling requirements, and greatly simplifying management and deployment,” Acoca added. “The new SFP-ER is absolutely essential for anyone who needs to push his Ethernet service beyond copper’s normal limits.”

Since 1981, RAD has been recognized as a major manufacturer of high-quality access and backhaul equipment for data communications and telecommunications applications. Its solutions serve the data and voice access requirements of service providers, carriers, and enterprise networks, as well as utilities and transportation systems.

Also this summer, RAD introduced its latest offering today, the Airmux-5000 carrier-class point-to-multipoint Ethernet radio system – a wireless solution designed for business access users demanding high-capacity throughput with guaranteed bandwidth according to Service Level Agreements (SLAs) per subscriber.

The technology is designed to overcome the limitations created by WiMax and WiFi. Specifically, WiMAX (News - Alert) must be transmitted over a licensed band and WiFi does not guarantee Quality of Service (QoS) or SLAs.
