Ethernet and DC cables
Maximum cable lengths Ethernet
For all cnWave radios, the maximum cable length for data transmission over copper Ethernet (100BASE-TX, 1000BASE-T, 2.5GBASE-
T, 5GBASE-T, 10GBASE-T) is 100 m (328 ft) from the radio to the connected equipment.
The maximum cable length for fiber Ethernet (10GBASE-SR, 10GBASE-LR) connections depends on the fiber used. See SFP module
kits on page 19 for details of the Ethernet standards supported and maximum permitted cable lengths.
Power over Ethernet
The maximum length for supplying power from a 60 W DC injector over a CAT6A Ethernet cable is shown in " Maximum cable
length for power over Ethernet" below.
Table 15: Maximum cable length for power over Ethernet
Radio PoE enabled Maximum cable length
V3000 - 390 m
25 W 72 m
V5000 - 330 m
25 W Not supported
The available output power for auxiliary Power over Ethernet output in V3000 and V5000 is reduced at longer PoE cable lengths,
as shown in Table 16.
