Ethernet cables fit into the following two categories:

Straight-through cable, at both ends of which, the wires are crimped in the RJ-45 connectors in the same sequence. The cable connects different types of devices, such as a terminal device (PC for example) or router to a Hub or LAN switch. The network cables shipped with the router are standard cables.

Crossover cable, at both ends of which, the wires are crimped in the RJ-45 connectors in different sequences. The cable connects the same type of devices, such as PC to PC or PC to router. You can make crossover cables by yourself as needed.

Note:

In preparing network cables, shielded cables are preferred for electromagnetic compatibility sake.

2)Fiber-optic Ethernet interface cable

For the 10/100/1000M Ethernet interfaces on the RPU2, select single mode or multi-mode optical fibers depending on the type of the installed 1000Base-FX SFPs. As the interfaces that these SFP modules provide use LC-type fiber-optic connectors, you must use fibers with LC-type connectors for them. All these SFPs are hot swappable.

Note:

SFPs are optional. They are provided only when ordered.

Note:

The fiber-optic and electrical connections that a 10/100/1000 Mbps Ethernet interface provides cannot operate at the same time. By default, if both connections are present, the system considers the electrical interface as the operating interface.
