QSA Adapter Update

There are now two versions of QSA adapters available with Flexoptix.

 

100G to 1x 25G 40G to 1x 10G  
Q.1HG.PCT Q.PCT no EEPROM -
for Mellanox and all other devices (not for Cisco)
Q.1HG.PCT.U Q.1HG.PCT.U with EEPROM for some Cisco devices and other devices (configurable)
Q.1HG.PCT.M Q.1HG.PCT.M no EEOROM -
for Mellanox and all other devices (not for Cisco)

 

What does this mean for you?

The adapter without EEPROM is simply passing through the SFP+/SFP28 information to the QSFP+/QSFP28 port. Some devices can handle this because they identify that the EEPROM content was read on a QSFP+ port and set the port to breakout, bringing it up.

On the other hand, some devices only read the SFP+/SFP28 content on a QSFP+/QSFP28 port and attempt to identify the QSFP+/QSFP28 with it. This approach doesn't work because SFP+/SFP28 and QSFP+/QSFP28 have different memory maps.

With Q.1HG.PCT.U, we can configure the adapter as we do with "normal" QSFP+/QSFP28 transceivers (capable of 40G/100G). FLEXOPTIX can create a configuration that makes the device work with the plugged-in adapter in breakout mode.

If you'd like to give it a try, just let us know!
