Each type of media has a specific use case regarding the MX7000, with each type of
media there are various applications. The following sections outline where in the chassis
each type of media is relevant.
Note: See the Dell EMC Networking Transceivers and Cables document for more information
about supported optics and cables.
As seen in Table 9, SFP+ is a 10GbE transceiver and SFP28 is a 25GbE transceiver both
of which can use either fiber or copper media to achieve 10GbE or 25GbE communication
in each direction. While the MX5108n has four 10GBASE-T copper interfaces, the focus
is on optical connectors.
The SFP+ media type is typically seen in the PowerEdge MX7000 with the use of the
25GbE Pass Through Module (PTM) and using breakout cables form the QSFP+ and
QSFP28 ports. The following are supported on the PowerEdge MX7000:
• Direct Attach Copper (DAC)
• LC fiber optic cable with SFP+ transceivers
The use of SFP+/SFP28 as it relates to QSFP+ and QSFP28, is discussed in those
sections.
Note: The endpoints of the connection need to be set to 10GbE if SFP+ media is being used.
