2. Ethernet crossover cable - Wikipedia

   en.wikipedia.org/wiki/Ethernet_crossover_cable

   For this, fiber patch cables with duplex connectors are normally configured as crossover as is the on-premises wiring. [ citation needed ] Thus, a simple connection with two patch cables at each end and a section of fixed cable in the middle has three crossovers in total, resulting in a working connection.

3. Patch cable - Wikipedia

   en.wikipedia.org/wiki/Patch_cable

   A patch cable, patch cord or patch lead is an electrical or fiber-optic cable used to connect ("patch in") one electronic or optical device to another for signal routing. Devices of different types (e.g., a switch connected to a computer, or a switch to a router ) are connected with patch cords.

4. Registered jack - Wikipedia

   en.wikipedia.org/wiki/Registered_jack

   The micro ribbon connector, first made by Amphenol, that is used in the RJ21 interface, has also been used to connect Ethernet ports in bulk from a switch with 50-pin ports to a Cat-5 rated patch panel, or between two patch panels. A cable with a 50-pin connector on one end can support six fully wired 8P8C connectors or Ethernet ports on a ...

   A patch cable is an electrical or optical cable used to connect one electronic or optical device to another for signal routing. Devices of different types (e.g. a switch connected to a computer, or a switch connected to a router) are connected with patch cables.

6. Structured cabling - Wikipedia

   en.wikipedia.org/wiki/Structured_cabling

   Regardless of copper cable type (Cat 5e/6/6A), the maximum distance is 90 m for the permanent link installation, plus an allowance for a combined 10 m of patch cords at the ends. Cat 5e and Cat 6 can both effectively run power over Ethernet (PoE) applications up to 90 m. However, due to greater power dissipation in Cat 5e cable, performance and ...

7. Medium-dependent interface - Wikipedia

   en.wikipedia.org/wiki/Medium-dependent_interface

   These are referred to as MDI and MDI-X (medium-dependent interface crossover). When connecting an MDI port to an MDI-X port, a straight-through cable is used, while to connect two MDI ports or two MDI-X ports, a crossover cable must be used. Conventionally, MDI is used on end devices and routers while MDI-X is used on hubs and switches.
