The Oracle Quad 10Gb or Dual 40Gb Ethernet adapter comes with a factory default port mode of 4x10GbE, with only QSFP port 0 (A) enabled. This adapter supports two cabling option solutions: copper and optical.

Copper:
The copper solution does not require QSFP transceivers.
A QSFP to QSFP direct-attach passive copper cable is available in 1, 2, 3, or 5 meters. One end of the QSFP cable connects to the QSFP port on the adapter, while the other end connects to the QSFP port on the switch or other device that is configured for 10GbE speed.
A QSFP copper splitter cable is available in 1, 3, or 5 meters. The QSFP end of the cable connects to the adapter's top QSFP port, while the four pigtails connect to four different 10G SFP+ ports on the switch or other device.
Optical:
A QSFP SR transceiver connects to the adapter's QSFP port and the QSFP MPO to MPO optical cable, which is available in 5, 10, 20, 50, or 100 meters. One end of the QSFP 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 10GbE speed.
A QSFP SR transceiver connects to the adapter's top QSFP port and the QSFP optical splitter cable, which is available in 10, 20, or 50 meters. The QSFP end of the splitter cable connects to the QSFP transceiver on the adapter, while the four pigtails connect to four different 10GbE SFP+ transceivers on the switch or other device.
