Connecting a hybrid copper-fiber cable
Only the S6520X-54HC-UPWR-EI switch model supports connections by using hybrid copper-fiber
cables.
About a hybrid copper-fiber cable
A hybrid copper-fiber cable combines optical fibers and conductive copper wires within the same
jacket. It connects a hybrid optical-electrical switch and APs or remote modules. It transmits DC
power and data over the same medium, significantly reducing the cabling cost.
A complete hybrid copper-fiber cable consists of three sections: pigtail of the hybrid optical-electrical
switch, main cable, and pigtail of the powered device. You must connect the main cable to the two
pigtails on site.
Connecting a hybrid copper-fiber cable
1.
Use a utility knife to peel off an appropriate length of the black outer sheath from the main cable,
exposing the inside four cables, of which the two yellow ones are optical fibers, and the red and
blue ones are conductive copper wires.
2.
Connect the two conductive copper wires to the network port connector provided with the
switch, with the red wire connected to terminal A, and the blue wire connected to terminal B, as
shown by callout 1 in Figure2-36.
3.
Connect the network connector to a copper port on the switch, as shown by callout 2 in
Figure2-36.
4.
Fusion splice the optical fibers to the pigtail with LC connectors.
