Oracle^® Dual Port 25 Gb Ethernet Adapter User's Guide

Cable and Transceiver Overview

The Oracle Dual 25 Gb Ethernet adapter comes with a factory default port mode of 2x25GbE. This adapter supports two cabling option solutions: copper and optical.

Check the adapter product page for available transceivers and cables at https://www.oracle.com/networking/index.html.

• Copper:

  • The copper solution has the SFP28 transceiver attached.

  • A direct-attach SFP28 passive copper cable is available in 1, 2, 3, or 5 meters. The end of the SFP28 direct-attached copper splitter cable connects to the adapter's SFP28 port. The two pigtails connect to the SFP28 ports 1 and 2 on the adapter.

    Note -  When using SFP28 to SFP28 cables to connect the adapter to a 25 GbE switch, ensure that the SFP28 ports on the switch are configured in the 25GbE mode.

• Optical:

  • A SFP28 SR transceiver connects to the adapter's SFP28 port and the SFP28 optical cable, which is available in 5, 10, 20, 50, or 100 meters. One end of the SFP28 optical cable connects to the SFP28 transceiver on the adapter, while the other end connects to a SFP28 transceiver in a switch or other device that is configured for 25 GbE speed.

  • An SFP28 SR transceiver connects to the adapter's top SFP28 port. The SFP28 end of the splitter cable connects to the SFP28 transceiver on the adapter, while the two pigtails connect to two different 25 GbE SFP28 transceivers on the switch or other device.
