The Oracle Dual Port 25 /100 Gb Mellanox Ethernet Adapter card comes with a factory default port mode of 2x25Gb/e (25 Gb) or 2X100Gb/e (100 Gb) or 2x100 Gb/e (Mezzanine 100 Gb for x86 Server Support only). The adapter card supports the following cabling option solutions:
Copper:
25 GbE Adapter: The direct attach copper (DAC) solution has the SFP28 transceiver attached.
The straight through SFP28 to SPF28 passive copper cable is available in 1, 2, 3, or 5 meters.
The splitter QSFP28 to 4 SFP28 direct-attach copper cable is available in 1, 2, 3, or 5 meters. The QSFP28 end of the direct-attached copper splitter cable connects to switch port and the two pigtails connect to the SFP28 ports 1 and 2 on the adapter.
100 GbE Adapter: The direct attach copper (DAC) solution has the QSFP28 transceiver attached.
The straight through QSFP28 to QSPF28 passive copper cable is available in 1, 2, 3, or 5 meters.
Fiber Optical:
25 GbE Adapter: A SFP28 25GBase-SR or SFP28 25GBase-LR transceiver connects to the adapter's port.
The straight through Duplex LC Terminated Multi-mode fiber cable, which is available maximum lengths of 70 meters (multi mode OM3), 100 meters (multi-mode OM4), and 10 kilometers (single mode OS1). One end of the fiber optical cable connects to the SFP transceiver on the adapter, while the other end connects to a SFP transceiver in a switch or other device that is configured for 25 GbE speed.
100 GbE Adapter: A QSFP28 transceiver connects to the adapter's port.
The straight through fiber optical cable is available is available in 10, 20, 50, or 100 meters. One end of the fiber optical cable connects to the QSFP transceiver on the adapter, while the other end connects to a QSFP transceiver in a switch or other device that is configured for 100 GbE speed.
