Supported transceivers and cables

With the flexibility of the CN4093 switch, clients can take advantage of the technologies that they require for
multiple environments:
For 1 GbE links, clients can use RJ-45 SFP transceivers with UTP cables up to 100 m. Clients that
need longer distances can use a 1000BASE-SX transceiver, which can drive distances up to 220
meters by using 62.5 µ multi-mode fiber and up to 550 meters with 50 µ multi-mode fiber, or the
1000BASE-LX transceivers that support distances up to 10 kilometers using single-mode fiber (1310
nm).
For 10 GbE (supported on external SFP+ ports), you can use SFP+ direct attach copper (DAC) cables
for in-rack cabling and distances up to 7 m (up to 5 m for Omni Ports). 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.
To increase the number of available 10 GbE ports, clients can split out four 10 GbE ports for each 40
GbE port using QSFP+ DAC breakout cables for distances up to 5 meters. For distances up to 100 m,
the 40GBASE-iSR4 QSFP+ transceivers can be used with OM3 optical MTP-to-LC break-out cables
or up to 150 m with OM4 optical MTP-to-LC break-out cables. For longer distances, the 40GBASE-
eSR4 transceivers can be used with OM3 optical break-out cables for distances up to 300 m or OM4
optical break-out cables for distances up to 400 m.
