Carrier Ethernet Company RAD Unveils New Ethernet Extender for its System-on-an-SFP family

RAD Data Communications (News - Alert), a Carrier Ethernet company which provides access products and solutions for carriers, ISP's, cellular networks, service providers and corporate users across the world, announced the expansion of its unique System-on-an-SFP family with the addition of a new Ethernet extender.

The new SFP-ER is a miniature Ethernet extender that delivers 100 Mbps of Ethernet up to 550m (1,804 ft) over existing copper wires (4-pair), according to company officials.

Company officials said that the SFP-ER is 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.

The finger-sized SFP-ER is housed in a Small Factor Pluggable (SFP) enclosure. It can be easily attached to an Ethernet switch with an MSA-compatible 100 Mbps TX Serdes.

SFP-ER scores better than VDSL because it is symmetric and also minimizes the need to purchase external VDSL boxes. Thus it saves space, reduces power consumption and cabling requirements. With all these capabilities, it also simplifies management and deployment.

The full-duplex solution is ideal for in-building and campus connectivity. It saves significantly on laying fiber, say company officials.

“The new SFP-ER is absolutely essential for anyone who needs to push his Ethernet service beyond copper’s normal limits,” said Jacky Acoca, global business manager for Smart SFPs at RAD Data Communications, in a statement. 

Earlier in April, RAD Data Communications announced it has formed a partnership with the National Exchange Carrier Association (NECA). The deal enables NECA members that are looking to implement broadband and Ethernet applications to gain access to RAD's full line of Carrier Ethernet, Mobile Backhaul and Multiservice Access solutions.
