Port & Cable

PORT & CABLE / THE CAPABILITY LIBRARY

Read the cable.
Then read the whole path.

Separate connector shape, transport, cable capability, power direction and device support. A number printed on one component is not a promise for the entire connection.

Five separate checks

The port is only the beginning.

  1. FormConnector and component role.
  2. TransportImplemented protocol and version.
  3. CableQualified rate, construction and direction.
  4. PowerSource, sink and supported negotiation.
  5. EquipmentExact ports, intermediary and desired mode.
Read each promise separately. A cable power marking is not a video specification. Connector: Which form and role?. Data: Which documented transport?. Power: Which negotiated profile?. Video: Which host and display mode?. Then check every part of the actual path.
