Transceivers and cables
With the flexibility of the G8264CS switch, customers can choose the following connectivity technologies:
For 1 GbE links, customers can use RJ-45 SFP transceivers with UTP cables up to 100 meters.
Customers that need longer distances can use a 1000BASE-SX transceiver, which can drive
distances up to 220 meters with 62.5 µ multimode fiber (OM1) and up to 550 meters with 50 µ
multimode fiber (OM2), or the 1000BASE-LX transceivers that support distances up to 10 kilometers
with single-mode fiber (1310 nm).
For 10 GbE links, customers can use SFP+ direct-attached copper (DAC) cables for in-rack cabling
for distances up to 7 meters. These DAC cables have SFP+ connectors on each end, and they do
not need separate transceivers.
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.
To increase the number of available 10 GbE ports, customers can split out four 10 GbE ports for
each 40 GbE port by using QSFP+ DAC breakout cables for distances up to 5 meters. For distances
up to 100 meters, the 40GBASE-iSR4 QSFP+ transceivers can be used with OM3 optical MPO-to-
LC breakout cables or up to 150 meters with OM4 optical MPO-to-LC breakout cables. For longer
distances, the 40GBASE-eSR4 transceivers can be used with OM3 optical MPO-to-LC breakout
cables for distances up to 300 meters or OM4 optical MPO-to-LC breakout cables for distances up
to 400 meters.
For 40 GbE to 40 GbE connectivity, customers can use the affordable QSFP+ to QSFP+ DAC cables
for distances up to 7 meters. For distances up to 100 meters, the 40GBASE-SR4/iSR4 QSFP+
transceivers can be used with OM3 multimode fiber or up to 150 meters with OM4 multimode fiber.
For distances up to 300 meters, the 40GBASE-eSR4 QSFP+ transceiver can be used with OM3
multimode fiber or up to 400 meters with OM4 multimode fiber. For distances up to 10 kilometers,
the 40GBASE-LR QSFP+ transceiver can be used with single mode fiber.
For 8 Gb or 4 Gb FC links (supported on Omni Ports only), customers can use 8 Gb FC SFP+ SW
optical transceivers for distances up to 150 meters (at 8 Gbps speed) or up to 380 m (at 4 Gbps
speed) with 50 µ OM3 multimode fiber. For longer distances, the 8 Gb FC LW optical transceivers
can support up to 10 kilometers on single-mode fiber. These transceivers can operate at 8 Gbps or
4 Gbps speeds.
The supported cables and transceivers are listed in the following table.
