These simple, inexpensive Ethernet jack/plug combinations used for loopback testing and to convert a standard Ethernet cable to a crossover cable are a no-brainer. Every network person should have one ...

A connector used for diagnosing transmission problems. Also called a "wrap plug," it plugs into an Ethernet or serial port and crosses over the transmit line to the receive line so that outgoing ...

Abstract: This paper demonstrates the application of micro-electromechanical switches (MEMs) and SiGe logic devices for passive and active loopback testing of wide data buses at rates up to 6.4Gbps ...

Reported as a stable and convenient means to test Small Form-Factor Pluggable (SFP) and Small Form Factor (SFF) devices, the new LC Loopback assembly provides a durable thumb latch and contoured grip ...
