Transceivers and cables

With the flexibility of the NE1072T RackSwitch, customers can choose the following connectivity

technologies:

For 1 GbE links, customers can use RJ-45 fixed ports with UTP cables for distances up to 100

meters.

For 10 GbE links, customers can use RJ-45 fixed ports (10GBASE-T) with UTP Category 6a or 7

cables for distances up to 100 meters.

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+ to 4x SFP+ 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.

For 40 GbE to 40 GbE connectivity, customers can use the affordable QSFP+ to QSFP+ DAC

cables for distances up to 7 meters or QSFP+ to QSFP+ active optical cables for distances up to 20

meters. These DAC cables and AOCs have QSFP+ connectors on each end, and they do not need

separate transceivers.

With multimode fiber optic LC cables, customers can use the 40GBASE QSFP+ bi-directional

transceivers for distances up to 100 meters with OM3 MMF LC cables or up to 150 meters with

OM4 MMF LC cables.

With multimode fiber optic MPO cables, customers can use the 40GBASE-SR4/iSR4 QSFP+

transceivers for distances up to 100 meters with OM3 MMF MPO cables or up to 150 meters with

OM4 MMF MPO cables. For distances up to 300 meters, the 40GBASE-eSR4 QSFP+ transceiver

can be used with OM3 MMF MPO cables or up to 400 meters with OM4 MMF MPO cables.

For distances up to 10 kilometers, the 40GBASE-LR4 QSFP+ transceiver can be used with single

mode fiber LC cables.

The following table lists the supported cables and transceivers.
