Configuration notes:
Power cables are not included and must be ordered together with the switch (see "Power supplies
and cables" for details).
SFP/SFP+ transceivers and cables are not included and should be ordered together with the
switch, if required (see "Transceivers and cables" for details).
Transceivers and cables
With the flexibility of the G8052 switch, customers can choose the following connectivity technologies:
For 1 GbE links, customers can use RJ-45 UTP cables up to 100 meters. Customers that need
longer distances can use the 1000BASE-SX transceivers in the SFP/SFP+ ports, which can drive
distances up to 220 meters with 62.5 µ multi-mode fiber (OM1) and up to 550 meters with 50 µ
multi-mode fiber (OM2), or the 1000BASE-LX transceivers that support distances up to 10
kilometers with single-mode fiber (1310 nm).
For 10 GbE links (supported on SFP+ ports), customers can use direct-attached copper (DAC)
SFP+ cables for in-rack cabling for distances up to 7 meters or SFP+ active optical cables (AOCs)
for distances up to 20 meters. These cables have SFP+ connectors on each end and do not need
separate transceivers. For distances up to 30 meters, the 10GBASE-T SFP+ transceiver can be
used with Category 6a or 7 RJ-45 UTP cables.
For longer distances, the 10GBASE-SR transceiver can support distances up to 300 meters over
OM3 multimode fiber or up to 400 meters over OM4 multimode fiber. The 10GBASE-LR
transceivers can support distances up to 10 kilometers on single mode fiber.
For extended distances, the 10GBASE-ER transceivers can support distances up to 40 kilometers
on single mode fiber.
The supported cables and transceivers are listed in the following table.
