Miniature Network Security Device

CypherPlug® is a miniature IP-level network security device that encrypts traffic over any IP network. Its innovative design breaks through the barriers of cost and complexity for customers who seek a high level of security for their networks.


Part of the RAD Smart SFP Portfolio

SFP Sleeve Form Factor, Hosts Standard MSA Compatible SFPs

CypherPlug is an SFP sleeve form factor, capable of hosting any standard MSA compatible 100M or 1GE SFPs. CypherPlug transparently envelops a large variety of SFPs, enabling full reuse of customer equipment and seamless deployment over multiple access infrastructure types, such as short-haul and long-haul fiber connections, bidirectional single-fiber links, and copper lines.

The SFP sleeve is easily pluggable into standard MSA compatible SFP ports of switches, routers, DSLAMs and mobile base stations, eliminating the use of external power and reducing space and cabling expenses.

The CypherPlug functionality is based on a powerful FPGA that enables easy customization to additional or different customer requirements.
