MAM1Q00A-QSA

Q
What is the Mellanox MAM1Q00A-QSA?
A
The Mellanox MAM1Q00A-QSA is a QSFP+ to SFP+ adapter that lets you use a single-lane 10GbE SFP+/SFP transceiver or cable in a 40GbE QSFP+ port.
Q
What is it used for?
A
It enables cost-effective interoperability between QSFP+ and SFP+ devices, such as connecting a 40GbE switch or NIC port to a 10GbE SFP+ transceiver, DAC, or AOC.
Q
Does it support full 40Gb/s breakout?
A
No. It does not convert a full 40GbE link into four 10GbE links. It maps only one SFP channel to lane 1 of the QSFP+ connector; the other three lanes are unused.
Q
What speeds and modules are supported?
A
It supports 10GbE SFP+ and 1GbE SFP modules and cables that comply with relevant SFP MSA standards.
Q
How is it installed?
A
It is designed for use in a QSFP+ port on a switch or NIC, with an SFP+/SFP module or cable inserted into the adapter.
