November 10, 2009 --W. L. Gore & Associates has developed its “Limiting Port” SFP+ assemblies that are fully compliant with the SFF-8431 Revision 4.1 specification, Chapter 3, specification for limiting modules.
The company says that it developed the low power, passively equalized cable through the use of its patented Gore Eye-Opener+ conductor technology and an extremely low loss expanded PTFE cable dielectric. The product satisfies the limiting port specification up to seven meters, without using active technology.
The company says its SFP+ offering provides a lower cost alternative to active copper technology and expensive optical transceiver modules.
