Notes about Cables and Connectors
Cable and Connector Naming Conventions
The suffix to the model number indicates the length of the cable. For example, 5610-50 indicates a
50-foot cable. Sometimes the suffix indicates the cable length in inches, rather than feet. This typically
occurs on Y-cables or adaptor cables.
Some entries in the cable tables include the gender of the connector and the number of pins. For example,
EIA/TIA-232/M25-M25 indicates a cable terminated with a male DB-25 connector at each end.
Cable Lengths
Cables are available in standard lengths of 10 feet (3 meters), 25 feet (7.6 meters), 50 feet (15 meters),
75 feet (22.8 meters), and 100 feet (30 meters). Lengths of 100 feet (30 meters) to 600 feet (183 meters)
can be specially ordered.
