...connectors. To connect 9-pin PC ports to devices with 25-pin connectors, you’ll need a simple adapter cable. The most commonly used interface, RS-232 is ideal for transmitting data at speeds up to 20 kbps and over distances up to 50 feet (15.2 m).
...easy removal of the cable when required. • Replaces Connections and More • DisplayPort replaces the connections between the PC and any associated monitor, but it also does more than that. It can be used to replace the low voltage differential si...
...wire pairs within a cable. Alien Crosstalk, in 10-GbE systems, is the measurement of the signal coupling between wire pairs in different, adjacent cables. • Factors that affect Alien Crosstalk • The amount of ANEXT depends on a number of factors...
...the data. • LVD cables • Cables are very important when designing or upgrading a system to take advantage of Ultra2 SCSI. Cables and connectors must be of high quality and they should come from a reputable manufacturer to prevent crosstalk a...
...the bridge between one cable’s ferrule and another cable’s ferrule interface. The precision of the ferrule sleeve and its hole determines how well the fibers align, which affects the light signal transmission. • Fiber optic adapters are generally m...
