Transceivers and cables
With the flexibility of the CN4093 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 (OM1) and up to 550 meters with 50 µ (OM2) multimode
fiber, 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 or SFP+ active optical cables (AOCs) for distances up to 20 meters.
These 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, customers can split out four 10 GbE ports for
each 40 GbE port by using QSFP+ DAC or active optical 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.
